2/2 DIR. CONTR. PROPORTIONAL VALVE FOR WATER AND OIL HYDRAULICS

DN 25 TO 100, OPERATING PRESSURES UP TO 320 BAR

  • Pilot-controlled proportional valves
  • Pilot-control by means of own medium
  • Leakage-free sealing on valve seat
  • Force-controlles working piston
  • Smooth switching, no shock impacts
  • Wear parts are easy to access an fast to replace
  • Actuation magnet is protected against dirt and humidity
  • The proportional valve can be driven by a position control card BLS1 only

The 2/2 directional control proportional valves are particularly suitable for HFA liquids and clear water up to operating pressures of 320 bar maximum.

Via proportional pilot-control valves, the volume flow through the opening cross-section and the pressure difference on the valve are determined.
