3326 NORMALLY CLOSED ADJUSTABLE AIR PILOT RELAY VALVE 1/4” NPT
DESCRIPTION
The 3326 is a poppet-type, normally closed relay valve. The spring keeps this valve in a closed position. The supply line is blocked and the outgoing line is vented through the exhaust port. When air pressure enters the pilot port, the main spring is compressed. This will permit the supply air to flow through the out port and close the port to exhaust. Several spring ratings are available, up to 120 PSI. The valve lends itself extremely well for inter-locking and time-delay circuitry. Its all bronze and stainless steel construction will give many years of trouble-free service. This valve has a full flow, 1/4” capacity, without restrictions.
An optional inlet cap is available which is equipped with an adjustable flow control that permits the volume regulation of the supply air.
