The Bosch Rexroth M-SR 25 KE30-1X/V (R900385859) is a high-performance check valve, characterized by its cartridge design that allows for seamless integration into hydraulic systems. This valve falls under the MSR product family type and is designed to offer leak-free blocking in one direction, ensuring efficient and reliable operation in various hydraulic applications. The M-SR 25 KE30-1X/V is direct acting, with a poppet-type spool that guarantees swift response times and precise control.
With a maximum operating pressure of up to bar/psi and a nominal flow capacity, this valve can handle significant hydraulic flow rates while maintaining stability and performance. It is suitable for use with a range of hydraulic fluids including HL, HLP, HETG, HEES, HEPG, and HFDU, making it versatile for different system requirements. The sealing material used in the M-SR 25 KE30-1X/V is FKM, known for its durability and resistance to high temperatures and chemicals.
The valve's design allows for installation in block designs either as an angle valve or as a straight-through valve. This flexibility makes it adaptable to various system configurations. Additionally, it comes without pressure presetting and offers various optional cracking pressures to meet specific application needs.
The component series X signifies its place within the manufacturer's product line-up indicating adherence to stringent quality standards. Its compact size adds minimal weight to the system while providing robust performance. The Bosch Rexroth M-SR 25 KE30-1X/V is an essential component for those seeking reliable hydraulic control with customizable options suited to a wide array of operational demands.
