Clippard NPP Pneumatic Pinch Valves
The Advantages of Pinch Air Valves
Other valve types have internal passages that may cause small amounts of fluid to remain in the air valve. Pinch air valves have no areas of dead volume where fluid can become trapped. Only the inside of the tubing has contact with the fluid.
Common industries that utilise pinch valves for the benefit of isolating the fluid from a mechanical valve include:
- Drug dispensing
- Laboratory equipment
- Wastewater
- Medical devices
- Chemical
- Food and beverage equipment
- Ceramic/glass/plastic, and solids handling
Features
- Small, compact design
- Normally-Open or Normally-Closed styles
- Hygienic and easy to clean (replace tubes)
- Can handle whole blood and particulate matter
- Unobstructed flow path
- Each valve comes complete with 30 cm of selected tubing
- Wide variety of easily replaceable tubing sizes and materials available
- For optimum performance, all products are 100% tested

“Pneumatically actuated pinch valves are the preferred choice in explosive/hazardous environments…”
…where a shorted or overheated solenoid could become an ignition source. They are also able to deliver more force, making them a good option for applications that require the use of firmer (higher durometer) tubing. Another advantage is size—since pneumatically piloted units are able to provide more force, the size can be scaled down to fit into smaller, more compact spaces.
