The CVCS40C3W25020 model belongs to the Cartridge Valves series from Vickers and serves as a pressure-relief element in hydraulic automation circuits. It contains a relief insert and a cover with pilot control so the outlet pressure is modulated smoothly. The insert ratio of 1:1 balances pilot and main areas for predictable response, and the valve remains normally closed until system pressure reaches the 3.30 bar cracking point. A wrench with a hex locknut lets technicians adjust the relief setting without removing the unit from its cavity. The design withstands up to 350 bar and handles flows to 1700 l/min, allowing it to protect high-pressure, high-volume systems against overload.
An SAE-threaded gauge port supports convenient pressure monitoring, while the pilot port orientation follows ISO layout conventions for manifold compatibility. Buna-N seals contain fluid securely and tolerate working temperatures between −20 °C and 70 °C, covering typical mobile and industrial environments. Overall dimensions of 180.086 mm in length, 129.032 mm in width, and 81.788 mm in height let the valve fit standard size-40 cavities with clearance for service tools. These measurements also help designers stack multiple relief stations within compact blocks.
