The Model X134H Deadman Control is designed for use with aviation fuel. It utilizes a two-way valve with a balanced piston which is spring loaded to be normally closed. When the Model X134H is activated, the valve connects the supply hose to the outlet hose. When the lever is released, the Model X134H closes off the supply hose. The X134H Deadman Control maintains pressure in the outlet hose when the Deadman Control is closed.
