The valve has the functions of lifting, intermediate stop, proportional descending control handle and self-locking at intermediate stop position.

The air pressure can be adjusted arbitrarily during the descending process, which can control the oil return amount of the proportional air- controlled reversing valve to realize the proportional descending function.

The valve has a separate power take-off switch, which can control the dump truck power take-off to open and close. When the control handle is pushed to the down position, the power take-off switch is automatically turned off.
