Pressure Relief Cartridge Valve series DVPB−3

Pressure [bar]


Flow rate [l/min]


Pressure relief valves series DVPB−3 are two stage pressure relief valves with a seated pilot stage and a spool type main stage. When the pilot stage is active (main stage relieving), pilot oil is drained externally to port 3. Port 2 can therefore be pressurised without that pressure being additive to the valve pressure setting. The straightforward design delivers an outstanding price/performance ratio and good pressure− flow rate characteristics. In order to obtain a good pressure adjustment over the entire pressure range, the total pressure range is subdivided into 6 pressure stages. The pressure is set by means of an adjusting screw or a hand−knob. To safeguard pressure settings, the adjusting screw can be sealed with a tamper−proof cap.
