The Bosch Rexroth M-SR 25 KE05-1X (R900344778) is a high-quality check valve designed for hydraulic applications, featuring a cartridge design that ensures reliable operation and easy installation. This direct-acting poppet valve allows for leak-free blocking in one direction, making it an essential component for systems requiring unidirectional flow control. The M-SR 25 KE05-1X is part of the MSR product family and is suitable for use in block designs, including configurations as an angle valve or a straight-through valve.
With its NBR sealing material, the valve is compatible with hydraulic fluids such as HL, HLP, and HFC, ensuring versatility across different hydraulic systems. It offers a maximum operating pressure of up to 315 bar (4568 psi) and can handle a maximum flow rate of 50 l/min (13.2 gpm), catering to a wide range of flow requirements. The nominal flow rate further defines its capacity within system specifications.
This model's robust design does not come with pressure presetting, which allows users to select various cracking pressures according to their specific needs. The component series X denotes its place within the manufacturer's product line-up, indicating its modern design and adherence to current industry standards.
The M-SR 25 KE05-1X's compact size and weight are tailored for efficient use within tight spaces without compromising performance. As part of the MSR product type, this check valve exemplifies reliability and quality engineering suitable for diverse hydraulic applications where one-way flow is critical. Its straightforward functionality provides ease of use in maintenance and operation within hydraulic circuits.
