Rexroth DBW20 Pilot Operated Pressure Relief Control Valve

Rexroth DBW20 Pilot Operated Pressure Relief Control Valve

The Rexroth DBW20 normally closed/open pilot operated Pressure Relief Valve consists of one pilot operated pressure Relief Valve mounted with 2/2 way Solenoid Directional Valve. The open or closed position of the 2/2 way solenoid directional valve depends on the electromagnet spool movement to achieve, the solenoid energized is open the valve, the valve is closed when the solenoid is de-energized, the different directional valve operation is according to the different requirements of the system design and work.

There is a channel of the 2/2 way solenoid directional valve is connected with the pilot operated pressure relief valve, and another channel is connected with the oil return line to the tank, operating solenoid allows a part of the pilot relief valve drain the pressure or keeping the pressure in the Hydraulic System.
