The M-SR30KE05-1X/V belongs to the Hy-Check Valves series from Bosch Rexroth and functions as a direct-acting poppet valve for hydraulic automation circuits. It installs as a cartridge element, so the body can be screwed directly into a manifold block without external piping. A nominal size of 30 establishes the flow cross-section needed for medium-to-high capacity lines, while the angle valve KE design routes oil through a right-angle passage that fits compact manifold layouts. Two ports provide a straightforward check path, and a cracking pressure of 0.5 bar allows the valve to open with minimal upstream head loss. The component withstands continuous system pressure up to 420 bar, permitting use in high-pressure pumps and actuator feeds. A rated flow of 400 l/min limits velocity to prevent seat erosion, and a mass of 0.472 kg keeps the manifold lightweight for mobile or modular power units.
FKM sealing resists swelling when exposed to common mineral oils or synthetic fire-resistant fluids, extending service intervals in mixed-fluid plants. The allowed fluid temperature span from −20 °C to 80 °C (with the same 80 °C cap on ambient air) keeps the elastomer within its thermal range so the poppet seats reliably in hot or cold starts. Viscosity limits of 2.8 mm²/s minimum and 500 mm²/s maximum ensure that opening times remain predictable and that damping gaps do not cavitate. Compatibility with HL, HLP, HETG, HEES, HEPG, and HFDU media lets designers specify mineral, biodegradable, or phosphate-ester fluids without changing hardware. These parameters combine to maintain check integrity across diverse industrial and mobile hydraulic systems.
