Pilot-operated Pressure Reducing Valve Z3DR6VP2-1X/50

Core features and technical parameters
Working principle: As a pilot operated pressure reducing valve, it can maintain a constant outlet pressure (secondary pressure) and is not affected by fluctuations in inlet pressure (primary pressure) or changes in valve flow rate. When the secondary pressure exceeds the set value, the valve core acts to connect the actuator oil port (such as P port) with the oil tank (T port), achieving the overflow function and preventing abnormal pressure rise, thus having a dual function of pressure reduction and overflow.
Main features:
High performance: characterized by a flat pressure relief curve, high stability, and low hysteresis, ensuring precise system control.
Compact design: The stacked plate design makes it very convenient to stack between the directional valve and the bottom plate, saving installation space.
Flexible adjustment method: It is usually equipped with an adjustable spindle with an inner hexagon and protective cap, and can also be equipped with a locking knob with a scale.
Optional measuring port (MS type): The version with the suffix "MSV" in the model (such as Z3DR6VP2-1X/50MSV, which is similar to the one in your question) integrates a measuring port, which can be easily connected to pressure sensors or gauges for real-time monitoring and fault diagnosis of secondary pressure.
Key technical parameters:
Maximum working pressure: 350 bar
Maximum flow rate: 60 L/min
Set pressure range: 50 bar (for this model)
Weight: Approximately 2.8 kg
Connection standard: The installation surface complies with ISO 4401-03-02-0-05 (equivalent to NFPA D03) standard.
Sealing material: usually FKM (fluororubber), suitable for various hydraulic oils, including HL, HLP, HFC, HFD, etc
