Dry Pipe Valves Manufacturers

Dry pipe valve is a dry pipe sprinkler system water-supply control valve that makes possible the installation of sprinkler systems in buildings subject to freezing temperatures. It is designed so that air pressure in the piping system can hold back water pressure at the valve until such time as a sprinkler is activated. Upon such activation the air pressure in the system can decay sufficiently to cause automatic operation of the valve and admission of water into the system. The valve has a 5:1 pressure differential ratio.
