The RCG03D230 pressure control valve belongs to the Pressure Control Valves series from Vickers and is installed to maintain stable pressure levels in hydraulic automation circuits. It uses a pilot-operated actuation scheme so the main spool responds smoothly to system demands while minimizing energy loss. A two-stage configuration provides preliminary pilot regulation followed by main flow modulation, allowing accurate control at the rated maximum operating pressure of 3000 psi. The valve passes up to 12 gpm without exceeding its pressure limit, supporting medium-capacity lines in machine tools or presses. Pressure is set with a screw and locknut so technicians can secure the desired value against vibration. An internal check valve permits free reverse flow when pressure is removed, preventing unwanted back-pressure buildup. All components are enclosed in a cast-iron body that resists fatigue and surface wear under cyclic loading.
For compact installation, the RCG03D230 attaches to a subplate or manifold and links to the circuit through an SAE 8 port threaded 3/4-16 UNF, simplifying block mounting and permitting rapid replacement during maintenance. Dynamic sealing is handled by nitrile elements that retain elasticity across the specified temperature span and resist petroleum-based hydraulic oils, which are the designated working fluids for this model. The valve maintains performance when oil cleanliness is kept at ISO 4406 code 19/17/14, limiting particle-induced spool erosion. Reliable operation is sustained from −4 °F to 158 °F, so the unit can work in unheated shops or warm production cells. Overall dimensions measure 178.6 mm in height and 2.81 in in length; these compact proportions let the valve sit among adjacent control elements without clearance issues.
