This unique version is typically used for operating hoppers on many types of trailers hauling different types of aggregate. The valve has solenoid and handle operators. The solenoid permits remote operation of the valve. The handle operates in conjunction with a bleeder button which depressurizes the air spring return allowing the handle to be moved. Manual operation can only be obtained with the solenoid de-energized.

Note: All subbase ports are 3/8" NPT.
