While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth M-SR 8 KE00-1X/V (R900371497) is a high-performance hydraulic check valve designed for efficient fluid control within hydraulic systems. This direct-acting poppet valve is part of the MSR product family and is characterized by its cartridge design, making it suitable for installation in block designs. The M-SR 8 KE00-1X/V operates without pressure presetting, ensuring leak-free blocking in one direction, which is essential for maintaining system integrity and preventing reverse flow.
With a maximum operating pressure of up to 315 bar (4568 psi) and a nominal flow capacity, this valve can handle significant hydraulic loads while ensuring precise fluid management. It accommodates various cracking pressures, which are available as optional features to meet specific application requirements. The M-SR 8 KE00-1X/V is compatible with multiple hydraulic fluids including HL, HLP, HETG, HEES, HEPG, and HFDU types, offering versatility for use in different hydraulic systems.
The robust construction of the M-SR 8 KE00-1X/V includes FKM sealing material known for its high resistance to heat and chemical exposure. This ensures long-term reliability and performance in challenging operating environments. The valve's design allows it to be used both as an angle valve and as a straight-through valve depending on the installation needs.
Due to its compact size and component series X classification, the Bosch Rexroth M-SR 8 KE00-1X/V integrates seamlessly into various hydraulic circuits without requiring extensive space or modifications. Its lightweight nature contributes to the ease of installation and maintenance while minimizing the overall impact on system dynamics.
In summary, the Bosch Rexroth M-SR 8 KE00-1X/V check valve stands out as a versatile solution for hydraulic systems requiring reliable one-way flow control with options for customization according to specific operational demands.
