RE 1139-0/09.07 KBPS Hydraulics Bosch Rexroth AG 3/1 Function, section, symbol General Proportional pressure relief valves of the KBPS.A type are remote control valves of poppet design and used to limit a system pressure. They basically consist of a pressure tube (3), a solenoid coil (), the valve seat (5) and valve poppet (). At a command value of 0 or in the event of a power failure, the minimum pressure is set. The actuation is performed by a proportional solenoid with central thread and detachable coil. The inner chamber of the solenoid is connected to main port and filled with hydraulic fluid. These valves can be used to infinitely adjust the system pressure to be limited in dependence upon the electrical command value. Basic principle A command value is selected on the control electronics for adjusting the system pressure. The electronics that is required for operation controls the solenoid coil with electric current in proportion to the command value. The proportional solenoid converts the electric current into a mechanical force that acts via the armature on the valve poppet (). The valve poppet () is pressed onto valve seat (5) and closes the connection between main ports 1 and. When the hydraulic force that acts on the valve poppet () is equal to the magnetic force, the valve regulates the set pressure by lifting the valve poppet () off the valve seat (5), thus allowing hydraulic fluid to flow from main port 1 to. In the event of a power failure, the minimum pressure becomes effective. Note! Any tank pressures (main port ) add to the set value in main port 1.
