Electrically Operated Pressure Relief Cartridge Valve series WUVPOC-2

Pressure [bar]


Flow rate [l/min]


Electrically operated pressure relief cartridge valves series WUVPOC-2… and WUVPLC-2… are size 10 valves with M24x1.5 mounting thread. They have a seated pilot stage and a spool-type main stage. Using the external pressure adjustment, the higher pressure p1 (relief setting) and the lower pressure p2 (a secondary pressure, or the unloaded pressure) can be varied smoothly and independently of one another without opening the hydraulic envelope, and either pressure can be selected. The “OC” model is mainly used for bypass circuits that can be unloaded with low p values (ON/OFF). The lower p values result in less heating of the oil and thus lower energy costs for the user. The “LC” model is mainly used for 2-pressure circuits (HI/LO). Using the re mote-control port Z, these valves can also be remotely con trolled or unloaded by means of external pressure relief valves or directional valves. When the pilot stage is active (pressure relief function), pilot oil is drained internally to port B. Any residual- or surge-pressure in port B (Tank) is there fore additive to the valve setting.
