PRESSURE REDUCING / RELIEVING VALVE
Mounting Surface NFPA D03 (ISO 4401-03-02-0-05)
Max Pressure 5000 PSI (350 bar)
Max Flow Rate 20 gpm (75 l/min)
The P03MSV-PDR valve is a modular three-way spool type direct operated pressure reducing / relieving valve. It is available with fixed or variable adjustment.
This valve is available with reduced pressure control on port A, B or P.
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 provides protection of the secondary circuit from pressure surges since it allows a reverse flow from the actuator to the T discharge line.
The variable adjustment version is supplied with a hexagonal head adjustment screw.
The fixed adjustment version is available preset to 285 psi (20 bar) 360 psi (25 bar) or 430 psi (30 bar) pressure.
The valve is normally open passing hydraulic fluid freely from P to P1 until the control port pressure reaches the pressure setting. The valve will shift to deliver just enough flow to maintain the controlled pressure.
The valve will divert flow to the T port to relieve the control port pressure when it exceeds the pressure setting.
