The CG2V10HWB10 belongs to the Pressure Control Valves series produced by Vickers and serves as a pilot-operated pressure relief unit that limits system pressure in hydraulic automation. This pilot-operated pressure relief design senses pressure at a pilot stage and actuates the main spool once the set value is reached. A maximum flow capacity of 650 L/min lets the valve accommodate high-output pumps without excessive pressure drop. The operating pressure rating of 350 bar on ports p and x supports heavy-duty circuits, while the back-pressure rating of 315 bar on port y allows remote vent lines to run at elevated levels. Subplate mounting enables quick removal for service without disturbing pipework, and the ISO 6264-10 (CETOP 10) interface ensures interchangeability with other size-10 CETOP hardware. Mounting bolts require 430 Nm of torque to keep the assembly secure under load. Pressure is set with a wrench and protective cover so the adjustment remains locked during operation.
Internal pilot and drain passages eliminate external hoses, which reduces leak points and simplifies installation. G 1/4 BSPP pilot and drain ports are provided for test equipment when circuit diagnostics are needed. All work ports use BSP threads to match common British Standard pipe fittings. The specified fluid cleanliness of ISO 19/17/14 defines the filtration level required to prevent spool wear and maintain consistent relieving action. Nitrile seals are fitted to ensure compatibility with standard mineral-oil fluids found in most hydraulic systems. The tank port t can tolerate 315 bar so return surges do not harm the housing. A weight of 4.4 kg keeps the component light enough for single-person handling during assembly or maintenance.
