The Bosch Rexroth KBPSL8BA/HCG24K4V (R901018588) is a high-quality screwin cartridge valve designed for precise pressure control in hydraulic systems. This direct operated proportional pressure relief valve, from the KBPS product family, features a decreasing characteristic curve and is intended for use in both mobile and industrial applications. With its maximum operating pressure of 350 bar (5076 psi) and a maximum flow rate of 30 l/min (7.9 gpm), the valve is capable of handling demanding tasks efficiently. The KBPSL8BA/HCG24K4V valve operates through electroproportional actuation, utilizing an integrated coil and poppet-type spool within its SUN TA cavity design. The electrical connection conforms to DIN EN standards, ensuring reliable performance and compatibility with various control systems. The FKM sealing material offers excellent resistance to high temperatures and chemical exposure, contributing to the durability of the valve. This model is particularly noted for its ability to maintain system pressure with precision due to its fine-balancing capability, which can be externally adjusted on the control electronics. Users can set the maximum system pressure via an adjustment screw, providing flexibility in application-specific requirements. In situations where power is lost, the valve automatically sets itself to the maximum preset pressure for safety. The Bosch Rexroth KBPSL8BA/HCG24K4V valve is also characterized by its direct acting feature which allows for immediate response to changes in command value or system conditions. It supports a supply voltage of 24 V DC and has a nominal flow rate that facilitates consistent hydraulic fluid management using HL, HLP, HEES, or HEPG types. Overall, this proportional pressure relief valve combines robust construction with advanced control capabilities to ensure efficient operation within hydraulic circuits where precise pressure limitation is critical.

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.
