The Bosch Rexroth KBPSR8BA/HCG24K4V (R901018597) is a high-quality screw-in cartridge valve designed for precise pressure control in hydraulic systems. This direct-acting, proportional pressure relief valve features a decreasing characteristic curve and is part of the KBPS product family. It offers an electroproportional type of actuation with an integrated coil, ensuring responsive and accurate performance. Capable of handling a maximum operating pressure of 350 bar (5076 psi) and a nominal flow rate, the valve operates efficiently within its specified limits. Its SUN TA cavity design allows for compatibility with standard cavities, facilitating ease of installation and maintenance. The DIN EN electrical connector ensures secure and reliable electrical connections for the solenoid actuator. Constructed with FKM sealing material, the KBPSR8BA/HCG24K4V valve is suitable for use with various hydraulic fluids such as HL, HLP, HEES, and HEPG, making it versatile for different hydraulic applications. The poppet-type spool within this normally closed valve ensures leak-free operation when in the closed position. This Bosch Rexroth valve's design allows for fine balancing of command value/pressure characteristic curves externally via control electronics. Additionally, users can manually set the maximum pressure using the adjustment screw provided on the unit. In case of power failure or when command value input is zero, the valve defaults to its set maximum pressure limit to safeguard system integrity. Ideal for both mobile and industrial applications requiring meticulous pressure regulation, this proportional relief valve exemplifies Bosch Rexroth's commitment to precision engineering and robust design in hydraulic components.

Valves of type KBPS.8B are direct operated proportional pressure relief valves (pilot control valves) in seat design and are used to limit a system pressure. At command value 0 or in the event of a power failure, the maximum pressure is set. Operation by means of a proportional solenoid with central thread and detachable coil. The solenoid's interior is connected to the main port and filled with hydraulic fluid. Dependent on the electric command value, these valves can be used to steplessly set the system pressure to be limited.
