The RG-03-Z2-10 valve belongs to the Pressure Control Valves series and is manufactured by Vickers for hydraulic automation systems that need stable line pressure. It is hydraulically actuated so it responds directly to fluid force without electrical input. A cast-iron body provides strength for continuous industrial duty, while an external drain lets excess fluid return to tank without influencing the set value. The valve mounts on a subplate or manifold, allowing quick replacement or circuit reconfiguration. Connection threads follow the SAE 8 (3/4–16 UNF) size so standard fittings can be used. It tolerates inlet pressures up to 210 bar (3000 psi), making it suitable for high-pressure supply lines, and passes up to 45 L/min (12 US gpm) to satisfy moderate flow demands. The internal layout gives it a pressure-control function that limits system force to a predetermined level.
Service temperatures from −20 °C to +70 °C permit operation in unheated plants and warm machine rooms alike. The unit adjusts outlet pressure anywhere between 60 and 125 psi, letting technicians match the setting to actuator requirements. Nitrile seals contain the fluid, and their compound is compatible with the specified petroleum oils used in most hydraulic machinery. Proper performance depends on oil cleanliness maintained at ISO 19/17/14 or better, protecting the precision surfaces inside the valve. The overall height of 7.03 in (178.6 mm), length of 2.81 in, and width of 2.93 in (74.45 mm) allow the component to fit densely packed manifolds without interference. These dimensions, together with the noted material and cleanliness constraints, define the installation envelope and maintenance practices for reliable system pressure regulation.
