The CS03F50 is a relief valve manufactured by Vickers within the Pressure Control Valves series and is used to guard hydraulic automation circuits against over-pressure events. The valve is actuated hydraulically, and its pilot-operated design keeps crack pressure consistent under varying flow. A 3000 psi maximum operating pressure allows integration into medium-pressure power units, while a 45 gpm maximum flow rate matches common pump capacities. The unit processes standard hydraulic oil to align with typical plant fluids, and a cast-iron body withstands shock and cyclic loading. Size 03 dimensions suit compact manifolds, and SAE straight thread mounting lets installers screw the valve directly into a block without additional adapters.
Porting and sealing characteristics finalize the configuration for service. A female SAE 10 (7/8-14 UNF) port accepts standard tube fittings, and all connections maintain the same female orientation to streamline hose changes. Internal fluorocarbon seals contain hot fluid, while outer nitrile rings prevent leakage where the valve meets its manifold. The housing stands 143.256 mm high, spans 168.402 mm in width, and measures 53.848 mm in length, enabling dense panel layouts. Continuous duty remains permissible up to 155 °F fluid temperature so elastomers stay within their thermal limits. These features let the CS03F50 deliver reliable over-pressure relief in space-restricted, high-cycle hydraulic systems.
