The Bosch Rexroth M-SR 15 KE05-1X/V (R900350794) is a high-quality check valve designed for hydraulic applications, featuring a cartridge design for easy integration into block designs. It operates as a direct-acting poppet type valve, ensuring leakage-free blocking in one direction and providing reliable performance in various hydraulic systems. This model is part of the MSR product family and is characterized by its robust construction and capability to handle a maximum operating pressure of up to 315 bar (4568 psi) with a nominal flow rate.
The M-SR 15 KE05-1X/V is suitable for use with a wide range of hydraulic fluids, including HL, HLP, HETG, HEES, HEPG, and HFDU types. It is designed without pressure presetting and can be utilized as an angle valve or straight-through valve depending on the installation requirements. The sealing material used in this check valve is FKM, known for its excellent heat resistance and chemical stability.
Weighing in at just . kg, it offers an efficient solution for systems requiring various cracking pressures while maintaining a compact footprint. Its maximum flow capacity reaches up to l/min (gpm), catering to applications that demand high fluid throughput. The M-SR 15 KE05-1X/V belongs to component series X, indicating its compliance with the latest engineering standards set by Bosch Rexroth.
Ideal for ensuring one-way flow in hydraulic circuits, this check valve is versatile enough to be used across different configurations while maintaining consistent performance. Its straightforward design promises ease of maintenance and long-term durability in demanding operational conditions.
