Associated actuator and circuit
Application and Service Scenarios
Use after confirmed valve leakage, unstable lowering, failure to open or inability to hold a load. Cylinder bypass, control valve leakage, pilot pressure and contamination can cause similar symptoms.
Inspection and Installation
Secure the load, release pressure and keep ports clean. Connect per the hydraulic diagram, then test smooth controlled movement, holding and pressure response under approved conditions.
Frequently Asked Questions
Does cylinder drift prove balance-valve failure?
No. Check the cylinder and control valve.
Can setting be adjusted in the field?
Only using authorized data, tools and procedure.
Why confirm flow direction?
Incorrect connection can prevent safe control.
Export Packing
Ports are capped and the valve is protected from contamination, adjustment damage and impact.
