�ǳ�web offers a variety of precision control solutions that resolve critical issues for commercial inkjet printing OEMs such as inconsistent ink flow, inefficient cleaning, uneven coating applications, and component durability.

Problem:

Inconsistent ink flow, inefficient cleaning, uneven coating applications, and inadequate component durability contribute to poor print quality and costly downtime.

Commercial inkjet printing OEMs face a variety of critical issues that significantly affect the quality and efficiency of their printing operations. The primary problem is often inconsistent ink flow, caused by air bubbles and blockages in the ink delivery systems. This inconsistency leads to frequent print quality defects and increased downtime for maintenance. Additionally, the cleaning system for the print heads and other components often does not effectively remove ink residues, causing frequent clogging. This reduces the lifespan of the print heads and necessitates more frequent replacements.

OEMs also often experience issues with the coating process for varnishing and laminating, which results in uneven application, product waste, and inconsistent finishes. In addition, the durability of the valves is often inadequate, leading to frequent replacements and increased operational costs.

�ǳ�web's precision control components enhance print quality and operational efficiency for commercial inkjet printing OEMs

To address these challenges, �ǳ�web precision control components are integrated directly into the OEM printing systems. For the ink delivery system, �ǳ�web’s PIV series valves, with their PTFE and PEEK bodies and absence of elastomers, are ideal for preventing the clogging issues that often result from ink drying on the valve poppet or orifice. This significantly reduces the risk of the valves leaking or sticking over time, ensuring reliable long-term performance. These valves are also ideal for use in the cleaning systems to control the flow of cleaning solvents to the print heads and other components. �ǳ�web media isolation valves efficiently handle various cleaning agents, ensuring thorough and effective cleaning processes that minimize clogging and extend the lifespan of the print heads.

�ǳ�web’s E2S series compact 10 mm media isolation valves can also be installed to regulate the ink flow from the storage tanks to the printing presses. These valves provide precise control and prevent air bubbles and blockages, ensuring a consistent and reliable ink supply. Additionally, the Cordis CPC series microcontroller can be integrated for ultra-high resolution and repeatable digital pressure control. This closed-loop system will maintain consistent pressure, further enhancing the ink delivery process and reducing defects.

For coating applications, �ǳ�web’s DR-2 series precision regulators provide fine control over the flow rates of coating materials, ensuring even application of varnishes and laminates. This reduces material wastage and achieves a uniform finish on the printed materials. �ǳ�web’s stainless steel push-quick fittings can also be installed to further enhance component durability and simplify maintenance. Constructed from high-grade 316 stainless steel, these fittings provide robust connections and allow full flow through the hose or tubing I.D., eliminating the smaller orifice often required in barb fittings.

By integrating high quality precision control components from �ǳ�web, commercial inkjet printing OEMs are able to realize significant improvements in their printing operations. The solutions �ǳ�web provides not only resolve existing problems, but also enhance overall efficiency, reliability, and quality of the printing processes.

�ǳ�web's PIV series media isolation valves feature a unique one-piece valve stem that functions as a sealing membrane while also supporting and centralizing the poppet in the seating area. This multifunctional diaphragm/poppet results in a simplified design with few parts, longer life, and minimal dead volume. All wetted areas of the valve are PTFE or PEEK, making this series ideal for use with corrosive media. Check out this quick video from Product Manager Attila Kiss to learn more.

VIDEO TRANSCRIPT:

Hello, let’s quickly review �ǳ�web’s PIV series isolation valves.

If you are familiar with �ǳ�web’s NIV series media isolation valve, this is very similar; only the PIV series utilizes PEEK material for the valve body, which may bring some advantages over the NIV series. The wetted materials of the PIV valve are a PTFE diaphragm and a PEEK valve body.

The combination of these two materials has one potential disadvantage over the NIV line but also provides two clear advantages.

The potential disadvantage is material compatibility. The NIV PTFE series is 100% PTFE, whereas the PIV is both PTFE and PEEK. So be sure to check the compatibility of your media.

Ok, now the advantages. By utilizing PEEK material for the valve body, the PIV series is able to achieve higher operating pressure. The NIV series maxes out at around 30 psig, while the PIV series is rated up to 100 psig—a clear advantage if you require higher operating pressure. The second advantage is life. With the durability of PEEK, the PIV series has nearly ten times the life of the NIV series.

So, if your duty cycles are high and you need a longer life, yet do not need the chemical compatibility characteristics of PTFE, then the PIV is the right valve for you.

Like the NIV series, the PIV is available in four orifice sizes, each as a 2-way normally-closed, 2-way normally-open, or 3-way selector/diverter. The valve series is very compact and lightweight in design. All valves can be used bidirectionally and have minimal dead volume compared to other diaphragm valves on the market. Except for the NIV series, of course… Because they’re identical.

�ǳ�web manufactures this valve series ourselves here in the U.S. in Cincinnati, Ohio. As the manufacturer, we completely control our processes and production, which assures you of our quality and gives you flexibility in design. You can customize the valve body, materials, threads, pressure, and electrical characteristics for your application.

Industries and applications that commonly use these types of valves to isolate gas or liquid include drug dispensing, laboratory equipment, analytical, chemical analysis, sampling, life science, biotechnology, genetic research, gas chromatography, spectrometry, DNA synthesizing, blood analyzing, printing, diagnostic equipment, fermentation, water treatment, and more.

The Advantages of Manifold Mount Isolation Valves

What are the advantages of manifold mount isolation valves? �ǳ�web Product Manager Attila Kiss explains in this quick video.

Hi, I’m Attila Kiss, product manager of pinch and isolation valves at �ǳ�web. We’re here today to talk about manifold mount isolation valves.

Manifold Valves Make Maintenance and Repair Easier

As challenges are faced in the system’s layout and design, one aspect that is often overlooked is the system’s maintenance and repair. Having to change a valve can be difficult, especially if you have to remove the fittings, tubing, wiring harness, and especially if the valve is buried in your system. Using a manifold mounted valve can make the process much easier, quicker, and more serviceable. When there are multiple valves in the system, you should consider accessibility for the maintenance and replacement of the valves.

Manifold Valves Save Time

Manifolding valves is a good option, especially when you have multiple valves in your system. Mounting the valves directly to a manifold allows for simple maintenance by removing just two screws and disconnecting the valve, as opposed to disassembling fittings, tubing, and the wiring harness. Manifold valves should conveniently be located in the service panel on an exterior face of your device.

Manifold Valves Reduce Leak Points

Other advantages of manifold mounted valves vs. individually ported valves are that there are less leak points, there is less internal volume, and since there is no tubing or fittings connecting the ported valves the system is much cleaner.
