H.A.K. Pneumatic (3 Way / 3 Port / 2 Position) Double Air Piloted Control Normally Closed Valve, NPT 1/4” (3A320-08)
Description
* Pneumatic Air Piloted Valve: 3 Port 2 Position.
* A High-Quality Valve body is made of Aluminium material, with long-serving life; seals initially imported from Japan.
* The Anti-friction seal is added at both ends of the valve spool to make the valve spool more stable during the switching process and increase the valve lifetime.
* This is a Three-way, air-pilot valve with a spool design requiring an input pressure supplied to port P to actuate. The valve will not actuate when no pressure is applied.
* This type of valve is designed for AIR FLOW ONLY. The use of filtered lubricated air will prolong the life of the valve & its internal components.
