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
