PZM3 DIRECT OPERATED THREE-PORT PRESSURE REDUCING VALVE

PLEASE ASK FOR PRICE!

The PZM is a stackable three-port pressure reducing valve, direct operated. The valve is normally open and the hydraulic fluid flows freely through it. The spool is subjected to the pressure in the P path but also to the force of the counter spring. When the pressure in P1 exceeds the spring force, the valving element closes until the pressure is reduced to the set pressure value. The valve provides good adjustment sensitivity with reduced drain flow. The drain is connected to path T inside the valve. The valve is supplied with a hexagonal head adjustment screw.
