Electrically Operated Pressure Relief Cartridge Valve series WUVPB-1

Pressure [bar]


Flow rate [l/min]


Pressure relief valves series WUVPB-1… are size 16 electrically operated pressure relief cartridges with an 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 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.

  • Compact construction for cavity type EB – M42x2 to ISO 7789-42-06-0-07
  • Bypass circuit ON/OFF
  • 2-pressure switching HI/LO
  • With internal pilot-oil drain to 2
  • High pressure wet-armature solenoids
  • The slip-on coil can be rotated, and it can be replaced without opening the hydraulic envelope
  • Various plug-connector systems and voltages are available
  • All exposed parts with zinc-nickel plating
  • Can be fitted in a line-mounting body
