Dual Pilot Operated Check Valve, Cylinder Stud Fit-In
Dual pilot operated check valve with a cylinder stud fit-in body — it mounts directly onto the cylinder port studs, eliminating all external hose runs between the valve and the cylinder. Internal-external bonded seals and the banjo bolt are included in supply.
This installation method is widely used in mobile plant — particularly on excavator arm and boom circuits — where a compact, rigid, low-leakage load-holding solution is required.
