Clippard NPV Dual-Tube 3-Way valve feature low power consumption and high cycle life.

Clippard unveiled its NPV Series Miniature Pinch Valves, which are solenoid-operated devices designed to open and close tubes for controlling flow of liquids and gases. Unlike other valves, pinch valves have no areas or dead volume where fluid can become trapped. Only the inside of the tubing contacts the fluid. Clippard’s NPV Dual-Tube 3-Way valve comes in four sizes with multiple pressure range options to 30 psig. The valves feature a maximum pressure range of 20 to 30 psig, power consumption of 1.0 to 7.2 watts and a response time of 5 to 25 ms. NPV Series pinch valves are available with one tube or two tubes. The single tube versions function as standard “on/off” 2-Way valves and are available in Normally-Open or Normally-Closed. The two tube versions feature one Normally-Open tube and one Normally-Closed tube, allowing them to function as 3-Way valves.
