Inline Dual Pilot Operated Check Valve
Dual pilot-released load-holding in an inline body that mounts directly to a cylinder face or sub-plate. Both A and B circuit checks are contained in a single compact block, reducing the number of separate components and potential leak points compared to two individual valves.
Four port sizes are available in zinc plated steel as standard, with aluminium on request. The 3/4" size is cracking pressure 1 bar only.
