�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.

Solution:

�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 PQ Flow Controls Series

Product Information

�ǳ�web PQ Flow Control Series

PQ-FV In-Line Flow Controls can be easily added to existing circuitry and are lightweight and compact in size. Since it is a tube-to-tube connection, in-line flow controls may be installed as a meter-in or meter-out device.

The PQ-C Elbow Controls are ideal for low cost and lightweight applications when mounting directly to an NPT port on a cylinder or valve is required.

In the meter-out versions, intake air flows freely through the flow control; exhaust air is metered out through an adjustment screw. With the meter-in series, air is metered in through an adjustment screw; exhaust air flows freely. Control is varied through a finely threaded adjustment screw. A locking nut is provided so it can be secured in its final setting.

• Small, compact size
• Design flexibility and fast response
• Complete rotation of the valve body around the bolt
allows for optimum positioning of tubing
• Special adjustment needle design allows large adjustment
ranges with high precision
• Ideal for use with polyurethane, nylon, polyethylene
and polypropylene tubing

Installation Instructions

Installation of Tubing or Hose into fitting
1. Slowly push a clean and perpendicularly cut tubing into the fitting until it comes to a dead stop.
2. Pull the tubing back gently until the Gripper Ring of the fitting grips onto the tubing and has a good seal.

Removal of Tubing of Hose from fitting
1. Push in evenly on the two long oval sides of the Release Button.
2. Pull out the tubing while keeping the Release Button depressed.
3. To reuse the tubing; cut off the lodged portion of the previously used tubing evenly and perpendicularly.

Installation of Pipe Fittings with Pre-Applied sealant
1. Tighten fitting by hand, then turn it 2 or 3 turns with a wrench until it reaches the desired torque listed.
2. If the fitting is used and the sealant coating is not in good condition, apply Teflon® sealant tape to the threads.
