3327 Adjustable Differential Air Pilot Relay Valve 1/4″ NPT Normally Closed

The 3327 is a poppet-type normally closed relay valve. The diaphragm spring keeps this valve in a closed position. Various springs are available for this valve to bring the pilot pressure setting to a maximum of 120 psi.

This valve lends itself extremely well for a multitude of dual piloting applications. The purpose of the dual diaphragm is to avoid deflection of the diaphragms in two directions.

The 3326 is the non-differential version of this valve.

A repair kit 3327-RK is available for seal repair.
