The Bosch Rexroth KBPSR8AA/HCG24K40V (R901047001) is a high-performance proportional pressure relief valve designed for precise control in hydraulic systems. This direct-operated, screw-in cartridge valve features an increasing characteristic curve, ensuring smooth and stable operation. With a maximum operating pressure of 350 bar and a maximum flow rate of 100 l/min, the KBPSR8AA/HCG24K40V is engineered to meet demanding performance requirements. The valve boasts an integrated coil with a supply voltage of 24 V DC and utilizes an electroproportional type of actuation for responsive and accurate pressure regulation. The poppet-style spool within the valve ensures reliable operation in a normally closed position. It's compatible with a variety of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HEES, HEPR, HEPG, HFDU, HFDR, and HFAS. Designed with fine adjustment capabilities for the command value pressure characteristic curve accessible from outside the control electronics, this valve allows for precise system pressure settings. In the event of power failure or when no command value is given (0 signal), it automatically sets to the minimum pressure limit ensuring system safety. The KBPSR8AA/HCG24K40V fits into SUN TA cavities and comes equipped with FKM sealing material to withstand various operating conditions. Its robust build quality is reflected in its weight of approximately 1.2 kg. The electrical connector type is Deutsch DTP which provides secure electrical connections for consistent performance. This Bosch Rexroth proportional pressure relief valve is part of their esteemed KBPS product family and is distinguished by its direct acting feature which enables rapid response times and efficient system pressure limitation. Whether it’s used in industrial machinery or mobile applications, this component series A valve delivers reliability and precision when controlling system pressures in complex hydraulic circuits.
Proportional pressure relief valve, direct operated, increasing characteristic curve
Unpacked Weight: 0.432 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.
