The Bosch Rexroth M-SR 15 KE15-1X/V (R900387662) is a high-performance check valve designed for hydraulic applications requiring reliable, leakage-free blocking in one direction. This direct-acting poppet valve is part of the MSR product family, characterized by its cartridge design which allows for easy installation in block designs, including both angle and straight-through valve configurations. The M-SR 15 KE15-1X/V operates without pressure presetting and is capable of handling a maximum operating pressure of up to 315 bar (4568 psi), with a nominal flow capacity that ensures efficient system performance.
Constructed with FKM sealing material, the valve is compatible with a variety of hydraulic fluids including HL, HLP, HETG, HEES, HEPG, and HFDU. This versatility makes it suitable for diverse hydraulic systems and applications. Additionally, it offers various optional cracking pressures to meet specific operational requirements. The robust design of the M-SR 15 KE15-1X/V ensures durability and a long service life even in demanding conditions.
The product's direct pilot operation ensures fast and accurate response to changes in flow or pressure within the system. With its poppet-type spool, this check valve provides stable operation and contributes to the overall efficiency and safety of hydraulic circuits. The Bosch Rexroth M-SR 15 KE15-1X/V represents a reliable solution for professionals looking for quality components in their hydraulic systems.
