The Model X130A Deadman Control is designed for use with compressed air. It utilizes a three-way air valve which is spring loaded to be normally closed. When the Model X130A is activated, the valve shifts connecting the supply hose to the outlet hose. When the lever is released, the Model X130A closes the supply hose and vents the pressure from the outlet hose to atmosphere. The Model X130A has a large vent port to discharge air rapidly.
