The Inbal Dry Pipe Valve is specifically designed to control the flow of water to the dry pipe sprinkler system and to provide actuation of fire alarms when the system operates. The Inbal Dry Pipe Valve is used to separate the water supply
from the dry pipe sprinkler system, by providing a bubble tight seal as long as the valve is in a set position. The Inbal Automatic Water Control Valve which is used in this dry pipe system is a pressure operated, sleeve actuated, axial valve
designed for use in fire protection systems. The trim design allows low air pressure supply to control a higher water supply pressure.
