The Bosch Rexroth KBVSP3BA/LCG24K40V (R901193065) is a screw-in cartridge valve designed for precise pressure limitation within hydraulic systems. This pilot-operated proportional pressure relief valve features a decreasing characteristic curve and is part of the KBVS product family. With a maximum operating pressure of 350 bar (5076 psi) and a flow capacity up to 100 l/min (26.4 gpm), it is well-suited for both mobile and industrial applications. The valve's electroproportional actuation is achieved through an integrated coil, with the electrical connection facilitated by a Deutsch DTP connector. The KBVSP3BA/LCG24K40V valve operates normally closed and utilizes FKM sealing material for reliable performance. Its design includes a poppet-type spool within its RISO cavity, ensuring accurate and responsive control over system pressure. Users can fine-tune the command value pressure characteristic curve externally via an adjustment screw on the control electronics, providing flexibility in system calibration. In terms of safety, this model ensures that in the event of power loss, the system defaults to maximum set pressure to maintain failsafe operation. The valve's compatibility with various hydraulic fluids—including HL, HLP, HEES, and HEPG—alongside its robust construction makes it versatile across different environments and applications. Overall, the Bosch Rexroth KBVSP3BA/LCG24K40V offers reliable performance with fine-tunable control for sophisticated hydraulic systems requiring precise pressure management.

Unpacked Weight: 0.704 kg

Cartridge valve Mounting cavity R/ISO 7789-33-01-0-98 Pilot-operated proportional valve for system pressure limitation Suitable for mobile and industrial applications Actuation by proportional solenoid with central thread and detachable coil Fine adjustment of the command value pressure characteristic curve possible from the outside at the control electronics Via an adjustment screw, the valve is set to maximum pressure In the event of a power failure, maximum set pressure becomes effective

Type KBVS valves are pilot-operated proportional pressure relief valves in seat design and are used for limiting the pressure in hydraulic systems. They mainly consist of the screwed in proportional pilot control valve and the main valve. Dependent on the electric command value, these valves can be used to steplessly set the system pressure to be limited. At command value 0 or in the event of a power failure, the maximum pressure is set (fail-safe behavior).
