NPP Pneumatic Pinch Valves

Clippard’s NPP series miniature 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. The NPP series functions as a standard "on/off" 2-Way valve and is available in Normally-Open or NormallyClosed versions.

Pinch valves are especially well-suited for applications which benefit from a disposable flow path. Common industries that utilize pinch valves for 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.
