The Bosch Rexroth KBPSH8AA/HCG24K4V (R901049868) is a high-performance screw-in cartridge valve designed for precise control of system pressure in hydraulic applications. This direct-operated proportional pressure relief valve is part of the KBPS product family and features an increasing characteristic curve to ensure smooth operation. The valve is capable of handling a maximum operating pressure of 350 bar (5076 psi) and allows for a maximum flow rate of 30 l/min (7.9 gpm). It is equipped with an electroproportional actuation type and utilizes an FKM sealing material suitable for various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HEES, HEPR, HEPG, HFDU, HFDR, and HFAS. Designed with a poppet-type spool and an integrated coil for reliable performance, the KBPSH8AA/HCG24K4V features a normally closed normal position. The electrical connector conforms to DIN EN standards ensuring compatibility with various control systems. With its Sun TA cavity design, this Bosch Rexroth valve can be easily integrated into existing hydraulic circuits. A standout feature of this product is its ability to offer fine adjustment from the outside at the control electronics which enables users to precisely set the command value pressure characteristic curve. Additionally, in the event of power failure or when receiving a command value signal of 0 volts DC, the valve defaults to setting the minimum system pressure ensuring operational safety. The component series A signifies that it belongs to the latest iteration offering improved performance characteristics. With its robust design and advanced capabilities, this Bosch Rexroth proportional pressure relief valve is ideal for applications requiring exacting pressure control within their hydraulic systems.

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.
