Description
This limit valve is suitable for installation on the limit seat of a dump truck hydraulic cylinder. The dump truck lifts to the set position, and when the limit screw on the limit valve touches the limit plate, the limit rod retracts, and the limit valve cuts off the air supply while the exhaust port releases air. The cargo compartment stops at the set position, providing a safety limit function. The limit valve structure is reliable in strength, the limit valve rod retracts sensitively, and it has a long service life.

Product Features
The air limit valve is normally in an open state, with P-A being continuously connected. The air inlet P is connected to the lifting port of the control air valve, and the air outlet A is connected to the lifting port of the lifting valve. When the pressure limit air valve's valve stem is activated, P-A is cut off, and A-O starts to release air, causing the lifting valve to cut off the oil flow. The valve stem returns to the neutral position, stopping the lifting of the vehicle compartment.
