The Bosch Rexroth KBPSP8AA/HCG24K4V (R901047007) is a high-performance proportional pressure relief valve, designed for direct operation with an increasing characteristic curve. This screw-in cartridge valve is engineered to limit system pressure and is suitable for a variety of hydraulic fluid types including HL, HLP, HLPD, HVLP, HVLPD, HEES, HEPR, HEPG, HFDU, HFDR, and HFAS. The KBPSP8AA/HCG24K4V features a maximum operating pressure of 350 bar (5076 psi) and can handle a maximum flow of 100 l/min (26.4 gpm), making it ideal for demanding applications requiring precise pressure control. This valve is part of the KBPS product family and has been developed with an integrated coil and FKM sealing material for robust performance in challenging environments. The electroproportional actuation allows for fine-tuning of the pressure characteristic curve externally at the control electronics. In the event of power failure or when the command value is zero, this valve ensures that the minimum set pressure is maintained. The design includes a poppet-type spool within its cavity Sun TA configuration to ensure reliable operation in its normally closed position. Its direct-acting feature provides swift response times to command value changes. Additionally, the DIN EN electrical connector ensures secure electrical connections for consistent operational integrity. With its compact size and component series A designation, this Bosch Rexroth proportional relief valve offers versatility and ease of installation in various hydraulic systems where space may be at a premium but performance cannot be compromised. The capability to directly operate as a pilot control valve in seat design further enhances its utility across different applications where system pressure limitation is critical.


Proportional pressure relief valve, direct operated, increasing characteristic curve

Unpacked Weight: 0.44 kg

Valves of type KBPS.8A are direct operated proportional pressure relief valves (pilot control valves) in seat design and are used to limit a system pressure. With a command value of 0 or in case of power failure, the minimum 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.
