CHAPEL check valve ARDPNU12, double pilot-operated
CHAPEL pilot-operated double check valve from the ARDPNU series. It blocks both lines of a double-acting cylinder and only opens when pilot pressure is applied on the opposite side, so the load stays in place in any position.
The pilot ratio determines the pilot pressure required for opening. The two types are assigned via the manufacturer number; before ordering, compare the port size and flow rate of the system with the valve data.
