M-SR30KE50-1X/

The M-SR30KE50-1X/ check valve belongs to the Hy-Check Valves series from Bosch Rexroth. The angle valve design (KE) turns the flow path by ninety degrees to simplify manifold layouts in hydraulic automation circuits. With size 30, the valve provides a passage area scaled for installations that handle up to 400 l/min. A nominal pressure rating of 250 bar lets it operate in medium-pressure systems without additional reinforcement. The port is cut to a G 1 1/2 thread, so connection to standard pipe fittings is direct. The element opens at a cracking pressure of 5.0 bar to prevent reverse flow while allowing rapid forward flow once the set threshold is reached. Housing length is 83.3 mm, dimensions that support compact block mounting inside power units.

Installation follows ZN 10001 threaded-plug guidelines, and a tightening torque of 400 Nm secures the valve against loosening in pulsating lines. The component can be oriented in any position, allowing horizontal, vertical, or inverted mounting to simplify routing when space is limited. An NBR sealing element keeps leakage low for petroleum-based fluids used in industrial presses and actuator banks. System oil must reach a cleanliness class of ISO 4406 20/18/15; the specified particle limit prevents contamination from hindering the poppet movement and sealing surface. With a mass of 0.47 kg, the cartridge adds minimal weight to manifolds and mobile equipment. These assembly and fluid requirements help the Hy-Check valve maintain consistent sealing behavior throughout pressure cycles in automated hydraulic machinery.
