3324 NORMALLY CLOSED ADJUSTABLE RELAY VALVE 1/4” NPT

DESCRIPTION

The 3324 is a normally closed, adjustable poppet-type valve which is controlled by a piston and spring arrangement. The spring keeps this valve in a closed position and pilot pressure will open the valve, allowing the air flow from the source of supply to the device actuated. The maximum pilot pressure is 700 PSI. The maximum control pressure (pneumatic) is 200 PSI. Many of these valves are used for clutch and throttle inter-locks in marine propulsion applications, where the gear box has to accumulate hydraulic pressure to lock up the forward or reverse clutch. After clutch lock up, the hydraulic pressure will open this valve, allowing the throttle signal to go through to the engine speed setting device.

This valve is also available with dual piloting on special request.
