SYMBOL
DESCRIPTION:
A screw-in cartridge relief valve, pilot operated, protects the connected circuit from pressure overloads. The input system pressure is always compared to the merchanically regulated opening pressure.
OPERATION:
The system pressure higher than set cracking pressure opens the valve and unloads the circuit by connection to the tank. Additionally, it is possible to mechanically adjust two values of cracking pressure with the help of adjusting screws built into the end plug of the solenoid actuating system.
The two set pressure values can be remotely switched by solenoid. When the solenoid is switched on the valve is set to maximum pressure. The maximum adjustable pressure is defined by pressure range of valve. The minimum circuit pressure can be set from 7 bar to the set maximum pressure. The valve can be used in two ways - as a switcher between two set pressure values or as a combined relief - unloading valve when one pressure value is adjusted on min. system pressure 7 bar.

* Screw-in cartridge pilot operated pressure relief valve
