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.
