Pressure−Relief Cartridge Valve series DVPB−1

Pressure [bar]


Flow rate [L/min]


Series DVPB−1 cartridges 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. 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.
