Electrically Operated Pressure Relief Cartridge Valves series WUVPB-2

Electrically operated pressure relief cartridge valves series WUVPB-2… are size 16 valves with M42x2 mounting thread. They have a seated pilot stage and a spool-type main stage. Using the external pressure adjustment, the higher pres sure p1 (relief setting) and the lower pressure p2 (a sec ondary pressure, or the unloaded pressure) can be varied smoothly and independently of one another without open ing the hydraulic envelope, and either pressure can be se lected. Using the remote-control port 3, these valves can also be remotely controlled or unloaded by means of exter nal pressure relief valves or directional valves. When the pi lot stage is active (pressure relief function), pilot oil is drained internally to port 2. Any residual- or surge-pressure in port 2 (Tank) is therefore additive to the valve setting.
