PROPORTIONAL PRESSURE RELIEF VALVE KBVST1AA/FCG24K40V

Unpacked Weight: 0.5377 kg

Cartridge valve Mounting cavity R/UNF10-01-0-06 Pilot-operated proportional valve for system pressure limitation Suitable for mobile and industrial applications Actuation by proportional solenoid with central thread and detachable coil Solenoid coil can be rotated Via an adjustment screw, the valve is set to maximum pressure In case of power failure, the minimum pressure is set Fine adjustment of the command value pressure characteristic curve possible from the outside at the control electronics

Valves of type KBVS are pilot-operated proportional pressure relief valves in spool design and are used to limit 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. With a command value of 0 or in case of power failure, the minimum pressure is set.
