The M-SR30KE30-1X/ check valve is built by Bosch Rexroth within the Hy-Check Valves series. As a direct acting model, the poppet shifts without pilot assistance, which shortens response time in hydraulic circuits. The poppet design forms a tight seal when flow reverses, preventing backflow. An angle valve layout identified by the KE code positions the body so line changes can be made without extra elbows. Nominal size 30 provides a passage area suited to medium-to-large lines, while two ports create a simple in-line path for oil. The cracking pressure is fixed at 3.0 bar, so flow begins once system pressure rises above this value. For mounting, the body fits an M48 × 2 bore thread, ensuring repeatable alignment in manifold blocks. The valve weighs 0.47 kg, allowing manual installation without lifting tools.
The component withstands operating pressures up to 420 bar, making it suitable for high-pressure supply lines. A maximum flow capacity of 400 l/min keeps pressure drop low during full-load operation. NBR sealing material resists mineral oils and maintains elasticity under dynamic cycling. Compatibility with HL, HLP, and HFC fluids lets the same valve serve mineral or water-glycol systems. A plug screw built to RN 143.28 standard closes the spring chamber, and its tightening torque of 325 Nm prevents loosening under vibration. Because no pressure pre-setting is included, installers select external restrictions when custom opening behavior is required. Together these characteristics define the hydraulic performance of the M-SR30KE30-1X/ valve.
