PZM2 three-ports pressure reducing valve, direct operated, spool-type, made as modular version, with ports according to the ISO 4401 standards, which can be assembled quickly, without the use of pipes, under the ISO 4401-02 solenoid valves.

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 protects the secondary circuit from pressure surges since it allows a reverse flow from the actuator to the tank line.

MZD three-way spool-type direct operated pressure reducing valve. It is normally open in the rest position, and the hydraulic fluid passes freely from the P1 line to the P line.

The spool is subjected to the line P pressure on one side, and on the other side by the adjustment spring. When the pressure, in line P, exceeds the value set by the spring, the valve closes until the pressure in P (is reduced) equal to the calibrated value.

The valve construction provides good adjustment sensitivity with reduced drainage flow. The drainage is connected to line T inside the valve. The three-way design protects the secondary circuit from pressure surges; allows a reverse flow from the actuator to the T discharge line.

The valve is made as a modular version with ports, according to the ISO 4401 (CETOP RP 121H) standards, and can be assembled quickly, without the use of pipes, under the ISO 4401-03 (CETOP 03) solenoid valves. The variable adjustment version has a hexagonal head adjustment screw. Upon request, it can be equipped with a SICBLOC adjustment knob. The fixed adjustment version is settable at the value of 20, 25, or 30 bar pressure.

Pilot operated pressure reducing valve ISO 4401-05 (CETOP 05).
