Pneumatic Pinch Valves

Clippard’s NPP Series 2-Way 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 or dead volume where fluid can become trapped. Only the inside of the tubing has contact with the fluid.

Common industries that utilize pinch valves for the benefit of isolating fluid from a mechanical valve including drug dispensing, laboratory equipment, wastewater, medical devices, chemical, food and beverage equipment, ceramic/glass/plastic, and solids handling.

Zero Dead Volume
         » Fluid samples are not contaminated by the previous sample through the tube.
         » There is no dead volume, as the tubing holds all the media.

Unobstructed Flow Path
         » Many other types of solenoid valves have complex valve internals that obstruct flow.
         » Unobstructed flow is important when handling vital fluids. Pinch valves create minimal pressure drop.
