Clippard Pneumatic Pinch Valves

2/2, Normally-Open & Normally-Closed
Clippard NPP Pneumatic Pinch Valves

Clippard’s NPP Series Pneumatic Pinch Valves are air-piloted devices designed to open or close tubes for controlling flow of liquids and gases.

Other valve types have internal passages that may cause small amounts of fluid to remain in the valve. Pinch 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 fluid from a mechanical valve include: drug dispensing, laboratory equipment, wastewater, medical devices, chemical, food and beverage equipment, ceramic/glass/plastic, and solids handling.

“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.
