The VICI diaphragm valve has been designed for trouble-free use in applications requiring minimal maintenance and maximum lifetime, making it an ideal choice for the process industry, automated lab analyzers, or continuous-monitoring environmental analyses.

• Only 35 mm (1.375") in diameter
• >1,000,000 cycle lifetime
• Built in actuator

diaphragm valves

The diaphragm valve consists of plungers and ports arranged in a circular pattern, with the plungers controlled by the reciprocation action of two air actuated pistons. Maintenance procedures are greatly simplified, since a single screw holds the valve together and locating pins insure proper alignment. Extremely long lifetime, very short actuation time (10 milliseconds), minimum internal dead volume, and reliability have made this type of valve very successful in process gas chromatography for both sample injection and column switching.

If the sample is below ambient pressure, contact the factory about an optional model that works at subambient pressures.
