Hydraulic Lock Pressure Valve
A lock valve sits between the control valve and the cylinder and holds pressure when the lever returns to neutral. On a loaded front end loader, tipping trolley or lift platform this is what stops the arm creeping down under weight, and what holds the load if a hose lets go.
- Fitted on JIC front end loaders, tipping trolleys and lifting platforms
- Holds the cylinder position with the engine off
- Acts as a safety device against hose burst on a raised load
- Supplied with the fittings needed to splice into an existing circuit
Where it is used
Any machine that lifts and holds a load should have one. JIC fits them as part of the hydraulic package and supplies them separately for machines already in service.
