Applications

  • Cylinders on mobile and industrial equipment
  • Load-holding circuits in lifting and material handling systems
  • Hydraulic presses and clamping devices
  • Cranes, aerial platforms and winches
  • Any system requiring secure load holding in both directions

Installation Notes

  • Connect P1 and P2 to both sides of the actuator
  • Pilot pressure is required at both P1 and P2 to open the valve
  • Ensure the system is clean and use suitable filtration of 25 μm or finer
  • Do not exceed the maximum pressure or flow ratings
  • Properly tighten all connections to prevent leakage
