SUMMARY:  Pressure valves, KBPS -pilot serie 1x/

Due to extremely high demand, please call 888-651-5712 for availability

Valves of type KBPS.8B are direct operated proportional pressure relief valves (pilot control valves) in seat design and are used to limit a system pressure. At command value 0 or in the event of a power failure, the maximum 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.
