The Bosch Rexroth KBPSP8AA/HCG24K40V (R901064392) is a high-performance proportional pressure relief valve designed for precise control over hydraulic system pressures. This direct operated, screw-in cartridge valve features an increasing characteristic curve, ensuring smooth pressure transitions within systems. It is engineered for maximum operating pressures up to 350 bar (5076 psi) and can handle flow rates up to 8 l/min (2.11 gpm), making it suitable for a wide range of applications that require accurate pressure regulation. The KBPSP8AA/HCG24K40V valve operates with electroproportional actuation, utilizing an integrated coil and a Deutsch DTP electrical connector for reliable signal processing and easy connectivity. The valve's poppet type spool ensures consistent performance and durability under varying conditions. Designed with FKM sealing material, it offers excellent resistance to high temperatures and chemical degradation. This Bosch Rexroth proportional pressure relief valve is part of the KBPS product family, characterized by its direct acting mechanism which provides pilot control in a seat design configuration. It comes with a nominal flow rate and SUN TA cavity compatibility, facilitating straightforward installation within hydraulic circuits. The unit's design allows for fine-tuning of the command value from the exterior control electronics, providing users with the capability to precisely adjust the pressure characteristic curve according to system requirements. In the event of power failure, the valve defaults to a minimum set pressure, ensuring operational safety. Overall, the Bosch Rexroth KBPSP8AA/HCG24K40V offers robust construction and versatile functionality for systems that demand precise control over hydraulic pressures. Its compatibility with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HEES, HEPR, HEPG, HFDU, HFDR, and HFAS extends its applicability across different environments and applications.

PROPORTIONAL PRESSURE RELIEF VALVE KBPSP8AA/HCG24K40V

Proportional pressure relief valve, direct operated, increasing characteristic curve

Unpacked Weight: 0.46 kg

Cartridge valve Mounting cavity R/T-8A Direct operated proportional valve for system pressure limitation 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 In case of power failure, minimum set pressure

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.
