RV8-8-S-0-50

The RV8-8-S-0-50 relief valve is manufactured by Vickers within the Cartridge Valves series and protects hydraulic circuits by venting excess pressure when the preset threshold is reached. Flow capability is 8 GPM, allowing moderate volume passage in mobile or industrial systems. A screw-adjustment mechanism lets technicians fine-tune the cracking pressure without removing the valve from service. The unit follows the C-8-2 cavity standard so it seats properly in matched manifold bores and maintains correct alignment with port seals. Because it is supplied as a screw-in cartridge, installation is completed with a single threaded engagement, reducing assembly time and permitting quick replacement during machine downtime.

Overall length is 3.940 in, while both width and height measure 0.870 in; these compact dimensions permit stacking multiple valves in dense control blocks or confined actuator housings. A Buna-N seal set resists common petroleum-based fluids and preserves leak-free operation under cyclic pressure changes. By integrating its pressure element, spring, and seat in a single body, the cartridge achieves tight packaging that fits the previously noted cavity. The screw-in format also lets maintenance staff extract the valve vertically so surrounding plumbing remains undisturbed. Together, the dimensional envelope and compatible seal material support reliable pressure relief in automated hydraulic platforms where space and service access are limited.
