The RG03Z330 valve belongs to the Pressure Control Valves series and is produced by Vickers for hydraulic automation circuits. It is configured for pressure-control duty, so it keeps downstream pressure within a 60 to 125 psi adjustable range that technicians set with the built-in screw. A cast-iron body withstands mechanical stress and dampens shock loads that occur when systems cycle. Hydraulic oil is the accepted working medium, and flow enters a female SAE 8 port threaded 3/4-16 UNF to match common tube adapters. These construction features allow the valve to integrate into manifolds while maintaining tight pressure regulation.
The device passes up to 12 gpm without excessive pressure drop, accommodating compact pump sizes used in mobile or industrial installations. Its housing remains structurally secure up to 3000 psi inlet pressure, giving a broad safety margin above the adjustable outlet setting. Nitrile (Buna-N) seals retain oil and tolerate additive packages common in mineral fluids. Operating reliability extends from −20 °C cold-start conditions to 155 °F oil temperatures encountered during continuous duty. This temperature, pressure, and flow capability ensures that the pressure-control function specified for the valve type is maintained across the full working envelope.
