VICI Valco 1/16” 6-Port Mini Diaphragm Sampling/Switching GC Valve - 0.4 mm Bore, 300 psi gas, 175°C

This is a VICI six-port mini diaphragm sample injection and switching valve for use with 1/16” zero dead volume fittings. It has an internal bore size of 0.016” (0.4 mm) and can be used with air actuators for gas chromatography applications up to 300 psi gas at 175°C. 

It is useful for gas chromatography applications where the sample is above ambient pressure, but can also be used at subambient pressures, such as when the sample is pulled through the valve by a vacuum.

Actuator air (40-50 psi) is supplied to a side port with 10-32 female threads, allowing use of a variety of compression or barbed fittings. A 3-way solenoid is required for actuator use (sold separately)

The valve has a stainless steel stator, a polyimide diaphragm, and comes with stainless steel nuts and ferrules.

• Use the optional mounting kit—a ring that screws to a panel and clamps the valve collar—to surface mount a diaphragm valve.

• Purging improves sensitivity by preventing any air from diffusing into the flow path. The optional purge ring is equipped with two 1/16” ports for the purge gas inlet and outlet.
