Electrically Operated Pressure Relief Cartridge Valve series WUVPB-3

Electrically operated pressure relief cartridge valves series WUVPB-3… 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. When the pilot stage is active (pressure relief func tion), pilot oil is drained externally to port 3. Port 2 can there fore be pressurised without that pressure being additive to the valve pressure setting. All external parts of the cartridge are zinc-nickel plated to DIN 50979 and are thus suitable for use in the harshest operating environments.
