Lung medications are both expensive and critical for optimum ventilator performance and patient care. Nebulizing applications require pushing various medications, in combination with warm, moist air—or extra O2, if needed—to treat medical conditions like asthma, cystic fibrosis, obstructive lung disorders, and pulmonary disease. The medication mist is delivered through an endotracheal tube or a tightly fitted mask.

�ǳ�web has partnered with medical OEMs to deliver low-cost nebulizing application solutions that do not sacrifice functionality or chemical compatibility. By making a few simple modifications to our standard valve offering, our custom solutions save OEMs significant time and resources.

Precision Control Solutions

It is very challenging to precisely control the amount of medication inserted into lungs using pneumatic valves with ultra low pressure and limited power, but �ǳ�web has a variety of different valves that accomplish this very well. For example, �ǳ�web’s 10 and 15 mm electronic valves are ideal for these kinds of small space applications that require a fast and precise dose of medication.

�ǳ�web has over 75 years of experience in miniature pneumatic controls, which enables us to provide our customers with customized valve solutions quickly at the right price point you are looking for.

VIDEO TRANSCRIPT:

Hi, I’m Mike Kettering, Product Manager for electronic valves at �ǳ�web. What is a latching valve? A latching valve is an electronically actuated two-position valve that stays detented in the last position that it was actuated into. Just like a detented toggle stays in the last position that it was actuated to, a latching valve remains in the same state that it was actuated to.

I’ve never been over the pond, but apparently in Europe, these are commonly referred to as bi-polar valves.

The main benefit of using a latching valve is low power consumption. Since the valve only requires a pulse of power to change states, it can stay unpowered until the state needs to be changed.

�ǳ�web offers a two-wire, 10 mm latching valve as well as a three-wire 15 mm latching valve. To change the state of a 10 mm latching valve, the polarity to the coil simply needs to be inverted. The 15 mm latching valve is a three wire valve with one wire to actuate, one wire to de-actuate, and one common wire.

Thanks for watching. Don't forget to subscribe to our YouTube Channel and have a great day.

VIDEO TRANSCRIPT:

Hi there, I’m Mike Kettering, Electronic Valve Product Manager for �ǳ�web. �ǳ�web has many standard options for 10 and 15 mm valves. However, I understand that standard options aren’t always the perfect fit for every application. Today, I would like to share with you some of the custom valves that we’ve done in the past. I know customs can sound scary to many customers, however, half of �ǳ�web’s business is customs.

Here are a few examples of our custom valves that we’ve done.

Here’s a really simple one, it’s a 10 mm valve with extra long wire leads.

Here is a 15 mm latching valve with a custom 4.3 volt coil on it. They needed the 4.3 volt coil for a lithium ion battery pack in a mobile application.

Here we have two custom 15 mm 2-way valves with EPDM seals on a manifold with custom fittings for use with refrigerant.

Here we have a 15 mm 3-way valve with custom low temperature seals and a DIN connector which allowed our customer to go from DIN to a Deutsch connector for IP protection.

And finally, we have a bank of 15 mm 3-way valves with custom orifice and spring configuration to achieve 250 psig working pressure.

I hope this helps you understand what’s possible with �ǳ�web custom valves. For more information, please visit us at clippard.com. Thanks, and have a great day.

How to Select Electronic Directional Control Valves

Rachel Desenberg — Tue, 18 Sep 2018 15:35:22 +0000

Category:

Troubleshooting

Selecting the appropriate valve for any application is imperative to ensure proper direction of flow, flow rate, exhaust function, and even basic valve functionality.

Valve Function

Valve function outlines the number of flow paths a valve has as well as the positions of a valve. The flow paths or ports are referred to as ways in the valve function. The number of positions is how many different positions that valve can be in.

2/2 Valves

A 2-way 2 position valve is known as a 2/2 valve. A basic example of a 2/2 valve is a ball valve. A basic ball valve has two ports (in and out) along with two positions (open or closed).

3/2 Valves

A 3-way 2 position valve is known as a 3/2 valve. A basic example of a 3/2 valve is a pilot valve like the E310A-1W012 10 mm valve from �ǳ�web. A pilot valve is used to send a pressure signal when actuated and exhaust that signal when de-actuated. This valve has 3 ways (in or supply, output, and exhaust) along with 2 positions (closed—pressure blocked with the outlet vented to atmosphere, or open—pressure connected to outlet and the exhaust blocked).

4/2 Valves

A 4-way 2 position valve is known as a 4/2. These valves are common in double acting cylinder applications where they are always supplying pressure to one side of the cylinder while venting the opposite side to atmosphere.

5/2 Valves

A 5-way valve is essentially the same function as a 4/2, but with the added benefit of independent exhaust paths for each output port. This is most commonly not referred to as a 5-way, but a fully ported four way valve. This allows the designer to have specific controls on the exhaust paths for either the extend and the retract exhaust paths. Some manufacturers do not reference 5/2 or 4/2 when offering a 4-way valve and although the differences are subtle, it may be import to your specific application.

6/2 Valves

Less common but still needed in specific applications, the 6-way valve is similar to having two 3-way valves mechanically tied within a single valve. Applications that require fail safe feature that assure that both valves will actuate at the same time are ideal for this function.

3 Position Valves

Some valves may have 3 positions in their function, which allows all ports to be blocked or open to atmosphere. These can be electronic valves or manual control valves that are spring centered with no power. These valves are not very common and are used for specific applications to either lock in a specific position of a cylinder or to open paths to atmosphere allowing the cylinder to be mechanically or manually positioned.

Valve Porting

Valve Porting pertains to the usability of the port and the direction of flow through the valve in different positions. There are two key points we will cover. First, the usage of the port—can we physically connect to the port? And second, the flow direction that the valve must accommodate for the application.

Fully Ported

A "fully ported" valve is any valve that you can physically capture or plumb to all the ports. This does not mean that all the ports are necessarily threaded, but this does mean that the flow path can be captured via a specific method opposed to a vent hole that goes to atmosphere.

Fully ported valves are ideal for applications where the media needs to be plumbed, for example: in clean rooms where all gases must be vented external to the room. �ǳ�web's ET-2-12 with threads on the inlet port and threads on the outlet port could be referred to as fully ported since all the ports on the valve can be plumbed, but the ET-3-12 is not fully ported as the exhaust path is vented through small holes in the valves cap. Hence �ǳ�web's offering of the ETO-3-12 fully ported version of the ET-3-12.

It is important to note that "fully ported" does not specify that all ports can be pressurized, only that they can be ported.

Bi-Directional

A bi-directional valve is a 2/2 valve that is not sensitive to which port is the inlet or the outlet. In Europe this is referred to as a bi-stable valve. Bi-directional valves are necessary for demanding applications where the higher pressure differential could be on either the inlet or the outlet.

A common ball valve is a simple example of a valve that doesn't care what side the pressure is coming from and works in either direction. This valve would be known as bi-directional.

The opposite valve to this would be a check valve, which flows in a single direction only.

Universally Ported

What about the possibility of a valve with more than two ports that is fully ported and bi-directional? This would be a universally ported valve. A 3-way universally ported valve can be configured for six functions, such as: 3/2 normally-closed, 3/2 normally-open, 2/2 normally-closed, 2/2 normally-open, selector, or even diverter.

It is important to note that not all fully ported 3/2 valves are universally ported.

Electronic Valve Actuation Types

The actuation is what shifts the valve from one position to another and there are two popular types that need to be considered in selecting the proper valve for any application. The actuation can be any of the functions or porting discussed above and is another valve characteristic that is important to understand.

Direct Acting

Direct acting valves are simple in design since the actuation of the valve directly translates into the change of the position. This is typically achieved by moving the valve element via a magnetic coil. All of the �ǳ�web EV Series valves are direct acting since energizing the coil directly lifts the spider (a flat armature spring) to change the flow state. The benefits of direct acting valves are that they have no minimum pressure requirements, fast response time, and long life due to few moving parts. The lack of pressure requirements makes the valve design ideal for universally ported functions. �ǳ�web's EVO-3-12 is a great example of a universally ported valve. The EVO-3-12 can be used with 80 psig on the normally-open inlet port, vacuum on the normally-open exhaust and select between them for an output.

Pressure Assisted

Pressure assisted valves are the most common valves used in automation applications. They rely on the pressure supplied to the valve to assist with actuation. The amount of force available from pressurized air to shift a valve is far greater than the force that can be generated from a magnetic coil on a direct acting valve with similar flow and pressure ratings. Once the internal pilot valve opens the pressure will assist the valve in shifting. This allows the ports to open and the valve to flow at high flow and/or pressures.

The benefit of pressure assisted valves is that they can take little electrical power because they are using the power of pressurized media. This allows for a smaller overall size for the given flow rates and port size. The drawbacks can be that they require a minimum pressure and don't allow universal porting options unless the pilot pressure is from an external force.

Pressure assisted valves are generally engineered for specific applications to achieve the maximum flow and pressure ranges while using the smallest amount of electrical power possible. Other pressure assisted valves that do not have internal pilots are balanced and tuned so that pressure works in conjunction with spring forces and the coil to lift the seat and allow for flow. An example of a pressure assisted valve is the �ǳ�web Maximatic MME-41PES-D012. Energizing the coil on the MME-41PES-D012 applies pressure to a piston to shift the spool in the valve.

Automated Spool Valve Assembly Machine Increases Efficiency, Boosts Capacity

Rachel Desenberg — Mon, 02 May 2016 14:12:56 +0000

Category:

Applications

�ǳ�web has years of experience manufacturing valve components with automated CNC machines that have the capacity to run lights out 24/7. This gives �ǳ�web repeatable performance, consistent quality, lower cost, and higher capacity. Over the past year, �ǳ�web has developed several new automated machines to bring these same benefits to the assembly side of the company's operations.

One of these such machines is this Automated Spool Valve Sub-Assembly Machine. As assembly staff heads home to be with their families, this machine continues building spool valve sub-assemblies for �ǳ�web's popular MAV, MJTV and FV Series spool valves. These components will be assembled overnight, ready for the final product assembly in the morning.

�ǳ�web's Automated Spool Valve Sub-Assembly Machine utilizes a variety of �ǳ�web automation components, including stainless steel cylinders with GMR switches, flow controls, customized pinch valves, Maximatic® FRLs and valve banks, along with �ǳ�web fittings and tubing, in combination with an Epson robot and a Horner PLC.

�ǳ�web cylinders are integral in the automation of a variety of tasks, including dispensing the valve spools and transferring the o-rings into position. Brian Kettering, Electro-Mechanical Automation & Robotics Technician for �ǳ�web Instrument Laboratory, explains, "Cylinders with GMR switches transfer the o-rings from a feeder track onto a mandrel, and feed the spools from a bowl into a nest to be picked. When a part is sensed, the cylinder retracts back into position and waits for the robot to finish its cycle."

"These machines improve efficiency and consistency in our assembly department," says Kettering. "They boost our capacity and improve the quality of our products without increasing cost."

Laboratory Automation for Pesticide Residue Analysis

Rachel Desenberg — Sun, 28 Feb 2016 15:00:06 +0000

Category:

Applications

To help keep consumers safe, laboratories test fruits, vegetables, and other foods for pesticide residues. Cutting edge laboratories are now able to test more of these samples than ever before—with improved precision and greater accuracy—through automation made possible with �ǳ�web miniature pneumatic valves.

An October 2014 report by the U.S. General Accountability Office (GAO) suggests the Federal Drug Administration (FDA) and the U.S. Department of Agriculture's (USDA) Pesticide Data Program "have room for improvement in the way they collect and share data on pesticide residues on fruits and vegetables and other food." The GAO claims that the FDA's "approach to monitoring for violations has limitations," pointing to the fact that while the FDA shows that "pesticide residue violation rates in 10 selected fruits and vegetables were low" from 2008 to 2012, "less than one-tenth of 1% of imported shipments in 2012" were tested for the pesticides. However, cutting edge laboratories now have the potential to test more samples thanks to an innovative new machine designed to increase efficiencies in the pesticide residue analysis process.

The most common method for examining pesticide residues in fruit, vegetables and other foods is known as the QuEChERS Method. QuEChERS (pronounced "catchers") stands for Quick, Easy, Cheap, Effective, Rugged and Safe. Originally published in 2003, this method has since been accepted around the world and is possibly the most used preparation method for multi-residue analysis today. Using the QuEChERS Method, the analyst homogenizes a sample (fruits, vegetables, etc.) in a blender and puts it in a centrifuge tube with a reagent, then agitates it for one minute. The reagents used depend on the type of sample to be analyzed. Following this, the sample is put through a cleanup column prior to analysis by gas-liquid chromatography.

The AutoMate-Q40, designed by Teledyne Tekmar, Mason, Ohio, is the first product specifically designed to optimize and automate the QuEChERS extraction process. It enables laboratories to achieve improved precision and accuracy for QuEChERS sample preparation while increasing sample capacity and improving workplace safety. Prepared sample trays are loaded into the machine and a method and/or schedule is selected through the TekTouch™ software control. The chemist can now step away and perform other tasks, such as important data analysis, while the AutoMate-Q40 methodically executes a litany of manual tasks to complete the sample extraction. It decaps the sample vial, adds solvent and standard, recaps and vortexes the sample, decaps and adds salt to the sample, recaps and shakes the sample, centrifuges the sample and validates the sample's extract volume. If clean-up is desired, the AutoMate-Q40 will then pipette the sample extract into dSPE clean-up, shake the clean-up vial, centrifuge the clean-up vial, validate the clean-up extract volume, and pipette the clean-up volume into a final extract volume. Finally, the extract vial is returned to the sample tray for analysis.

This automation is powered by pneumatics, a decision that was ultimately based on cost and ease of programming. For Michael Maroon, Mechanical Engineer at Teledyne Tekmar, the choice was clear. "The air valve actuates, then the cylinder moves. As opposed to using a motor to drive a lead screw or a pulley or a belt until it hits an end stop—all while utilizing encoder feedback to verify how many steps were required to make the motion. It was simpler," says Michael. "For example, on our capping wheel where we're capping different diameter vials, we just want to push the wheel over apply a force on the vial, then spin it to remove the vial cap. Electronically, that would difficult to implement because a feedback device would be needed to signal how much force the unit is applying against the vial. That would be very time-consuming and costly to implement." Additionally, according to Tom Hartlein, Tekmar's Product Line Manager, "We know historically from using pneumatic solutions for our other product lines for 30+ years, our warranty values are typically less than 1%. That translates into a high probability of success using pneumatics."

When the time came to specify components, Tekmar consulted with Isaacs Fluid Power who recommended �ǳ�web's line of 10 and 15 mm valves. Offered in both Normally-Open or Normally-Closed models, these valves are perfect for small areas where compact electronically-controlled pneumatics are needed. According to Michael Maroon, an added benefit was the flexibility of having the same valve throughout the machine, thereby simplifying the need for inventory. In addition to the pneumatic valves, other �ǳ�web products integral to the machine include fittings, pressure regulators, and tubing. Working in concert, Teledyne Tekmar, �ǳ�web Instrument Laboratory and Isaacs Fluid Power engineer, manufacture and build the components and subassemblies that make up the machine's pneumatic controls.

Teledyne Tekmar's AutoMate Q-40 is an impressive example of laboratory automation made possible with �ǳ�web pneumatics. In addition to pesticide multi-residue analysis, other possible applications include analysis of polycyclic aromatic hydrocarbons (PAH) in seafood, analysis of veterinary drug residues in livestock, analysis of nutraceuticals and dietary supplements and more. Hartlein says, "the possibilities are basically unlimited. Generally, anything that goes through an extraction that requires a solid, addition of a solvent, shaking, centrifuging and pipette vetting is a candidate for the AutoMate-Q40."

Applications

The lack of standardized wound therapy methods and care contributes to unnecessarily long treatment and healing times. In addition, these factors contribute to excessively high costs borne by patients and health plans. Various new technologies and discoveries are bringing to patients the ability to work with their doctors to get wounds under control with pneumatics.

Hyperbaric Oyxgen Therapy for Wound Healing (HBO2)
Oxygen is one of the most versatile and powerful agents available to the modern medical device manufacturers. The therapeutic use of oxygen under pressure has been used to assist wound healing for almost 40 years. HBO2 provides pharmacological doses of oxygen to stimulate the tissue, thereby promoting a much quicker healing process.

Negative-Pressure Wound Therapy (NPWT)
Negative-pressure wound therapy is a therapeutic technique using a vacuum source that creates continuous or intermittent negative pressure inside the wound to remove fluid, exudates, and infectious materials to prepare the wound for healing and closure.

�ǳ�web has been successfully partnering with progressive companies in the design and development of innovative pneumatic solutions for both stationary and portable non-invasive topical wound therapy equipment.
