Pressure Relief Cartridge Valve series DVPB−2

Pressure [bar]


Flow rate [l/min]


Pressure relief valves series DVPB−2 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 internally to port 2. Any pressure at port 2 is additive to the valve setting, therefore port 2 should preferably be routed directly to tank. Using the remote control port 3, these cartridges can also be remotely controlled or vented by means of external pressure relief valves (e.g. DDPC−1L) or directional valves (e.g. WR22). The straightforward design delivers an outstanding price/performance ratio and good pressure drop − 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.
