NPV Series Miniature Pinch Control Flow of Liquids and Gas

Clippard’s NPV Series Miniature Pinch Valves have no areas or dead volume where fluid can become trapped while other valve types have internal passages that may cause small amounts of fluid to remain in the valve.

Clippard’s NPV Series Miniature Pinch Valves are solenoid-operated devices designed to open and 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, however, have no areas or dead volume where fluid can become trapped, the company says.

According to the company, energizing the solenoid retracts or attracts the plunger, which opens or closes the tube, while de-energizing the solenoid will allow the plunger to return to its original state.

Common industries that use pinch valves for the benefits of isolating fluid from a mechanical valve include: drug dispensing, laboratory equipment, waste water, medical devices, chemical, food and beverage equipment, ceramic/glass/plastic, and bulk and solids handling. Features of the pinch valves include four sizes with multiple pressure range options to 30 psig; a small, compact design; low power consumption; high cycle life; ability to handle whole blood and particulate matter; an unobstructed flow path; a variety of medical/laboratory and food grade silicone tubing available; and tubing is easily replaceable.
