Features/Design
Good corrosion resistance
All control circuits have a common pressure connection P and tank connection T
The consumer connection A is individually led out to the side
The plates are placed horizontally in a row and clamped together between starting block and end plate by tie bolts
With different connection threads
Valve banks by valves of the series WVH-4B, WVHX-4B and WVH-4B-Bi

Applications

  • Portable power units
  • Control of cylinders as superior and space saving alternatives
    to spool valves which require additional leakage free shutoff valves
  • Forming technology - clamping
  • Presses, test benches and systems
  • Lifting and transport systems
  • Hydraulic tools
  • Accumulator charching systems
  • Seat-tight pilot control of passive and/or active logic valves

Design

  • Pressure compensated design of hardened and specially grinded valve cones
  • Available as 2/2 or 3/2 directional poppet valve cartridges with solenoid actuation
  • Strong return springs
  • 360° turnable and exchangeable plug-in-coil
