The Rexroth S 25 A1.0/ is a high-performance, direct-operated hydraulic check valve designed to block oil flow in one direction while allowing free flow in the opposite direction. As a cartridge-style valve (insert valve), it is engineered for installation into standardized cavities, providing a leak-free seal and reliable performance in demanding hydraulic systems. With a robust construction, it can handle a maximum operating pressure of up to 310 bar, making it suitable for a wide range of industrial applications. This specific model, with material number R900420525, ensures precise hydraulic control and enhances system safety by preventing reverse flow.
