The Bosch Rexroth KBPSN8BA/HCG12K40V (R901137190) is a high-performance screw-in cartridge valve designed for precise pressure control in hydraulic systems. This direct-operated proportional pressure relief valve features a decreasing characteristic curve and is part of the KBPS product family, which falls under the Proportional Valve product group. It is specifically crafted to limit system pressure with fine control, making it suitable for both mobile and industrial applications.
The valve has an integrated coil and operates with a 24 V DC supply voltage, ensuring reliable electroproportional actuation through its Deutsch DTP electrical connector. The poppet type spool within the valve ensures normally closed operation, with the ability to open progressively in response to electrical command signals. The maximum operating pressure of the unit reaches up to 350 bar (5076 psi), while it can accommodate a maximum flow rate of 40 l/min (10.6 gpm), ensuring efficient performance even under demanding conditions.
Designed with an FKM sealing material and compatible with hydraulic fluids such as HL, HLP, HEES, and HEPG, this Bosch Rexroth valve ensures durability and compatibility with a wide range of system fluids. Its size and component series A designation indicate its compactness and adaptability for various installation requirements. With its Sun TA cavity design, the KBPSN8BA/HCG12K40V valve offers straightforward installation as a screw-in cartridge unit.
Moreover, users can externally fine-tune the command value-pressure characteristic curve via control electronics to meet specific system requirements accurately. In situations where power is lost, the valve automatically sets itself to maintain maximum set pressure for safety and system integrity purposes. The robust design combined with precise control capabilities makes this Bosch Rexroth valve an essential component for advanced hydraulic systems requiring reliable pressure relief functions.
