The Bosch Rexroth KBPSL8BA/HCG12K40V (R901064385) 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 features a decreasing characteristic curve and is part of the KBPS product family, which falls under the Proportional Valve product group. It is engineered with an integrated coil and FKM sealing material, ensuring durability and reliability in various operating conditions.
The valve's maximum operating pressure reaches up to 420 bar (6090 psi), with a nominal flow rate capacity, making it suitable for demanding applications that require meticulous pressure regulation. With its SUN TA cavity design, the valve can handle a maximum flow of up to 8 liters per minute (2.11 gallons per minute), providing efficient fluid control for both mobile and industrial systems.
Equipped with an electroproportional type of actuation, the KBPSL8BA/HCG12K40V utilizes an electrical connector of the Deutsch DTP series for secure and stable electrical connections. The poppet-type spool within this normally closed valve ensures leak-free operation when de-energized. The direct acting nature of this valve means it provides immediate response to changes in command values, enhancing system precision.
The unit operates on a 24 V DC supply voltage and boasts features like fine balancing of command value-pressure characteristic curve externally on control electronics and an adjustment screw for setting maximum pressure. In case of power failure, the system reverts to the pre-set maximum pressure, safeguarding against uncontrolled pressure spikes.
This Bosch Rexroth proportional valve is compatible with various hydraulic fluids including HL, HLP, HEES, and HEPG types, expanding its applicability across diverse hydraulic systems without compromising performance. Its compact size and component series A designation make it a versatile choice for integration into existing setups where space may be limited but robust control is required.
