A typical trucking application is called a "Belly Dump". This is an application where the driver in the cab can initiate the opening of a bottom clam shell trailer by pushing a button. The operator can also regulate the opening manually by using a lever on the valve. This valve is a 2 position, spring return, solenoid operated valve with an alternate manual lever. This valve is rugged and reliable for trucking operations.
