M-SR30KE15-1X/

The M-SR30KE15-1X/ check valve is produced by Bosch Rexroth within the Hy-Check Valves series and is intended for hydraulic automation circuits that require controlled flow through a single passage. The cartridge check valve configuration allows installation in standardized cavities, while the angle valve (KE) design places the ports at a right angle to simplify manifold routing. Direct-acting actuation links line pressure directly to the poppet, eliminating pilot passages and shortening response time. The poppet closure type produces a firm seal when the valve closes. A nominal size of 30 fits medium-diameter passages, and two ports establish a straightforward inlet and outlet. The cracking pressure is fixed at 1.5 bar, so the valve opens only once the upstream side surpasses that level, preventing flow at lower pressures.

The valve handles flow rates up to 400 l/min, matching the needs of pumps and actuators that move large volumes. Compatibility with HL, HLP, and HFC fluids lets users select mineral oil or water-glycol media without changing internal components. Any installation position is acceptable, giving designers freedom to orient the body as space permits. NBR sealing ensures poppet tightness under typical industrial temperatures and fluid chemistries. An overall length of 83.3 mm supports compact block dimensions, and a weight of 0.4915 kg permits manual assembly without lifting tools. These characteristics allow the valve to meet pressure and flow targets while fitting within restricted hydraulic manifold envelopes.
