UniPro™ Control Panel

A basic control panel activates the UniPro™ System in an emergency, then stops the air supply after 15 seconds to prevent large volumes of air or nitrogen from being vented after the valve has been closed. Powell can supply custom panels to control new or existing automatic and pad gas valves and detectors.
