Gas interception automatic normally closed solenoid valves that open when the coil is powered and close when there is no voltage. They can be equipped with a flow regulator and adjustable slow opening kit.
Madas automatic solenoid valves are normally closed: they open the gas flow when the coil is powered and close it when power is removed. That makes them the shut-off point for a gas detection system, which cuts power to the valve on alarm. We supply, install, commission and service Madas valves on natural gas and LPG lines, matched to the panel and pipe size.
