Spool hydraulic directional control valve PZM2

PZM2 - Direct-operated pressure reducing valves ISO 4401-02 (CETOP R02) The PZM2 valve is a three-ports pressure reducing valve, direct operated, spool type, made as modular version, with ports according to the ISO 4401 standards and can be assembled quickly, without use of pipes, under the ISO 4401-02 solenoid valves. The PZM2 is a normally open valve. The hydraulic fluid flows freely in the pressure line. When the inlet pressure in P exceeds the value set by the spring, the valve opens the outlet port to the tank line until the outlet pressure has been reduced to the set value. The valve construction provides good adjustment sensitivity with reduced drainage flow. The drainage to the tank line is internal. The three-ports design provides protection of the secondary circuit from pressure surges since it allows a reverse flow from the actuator to the tank line.
