EMACO Zone Control Valve Set

Zone Control Valve is a combined unit of signal butterfly valve, waterflow indicator, pressure gauge and test & drain valve assembled on fire protection pipeline network of sprinkler system. It separates the fire area into small distribution zone for indication and control. A sprinkler system must be capable of shut down after the fire has been controlled, and for periodic maintenance and modifications which function is achieved by using a Zone Control Valve. Because of fire sprinkler head or test valve activation, the indicator detects water flow and transmit signal to control system for action. After fire suppression, butterfly valve gets signal and close to shut down the water flow of the designated zone for recovering the system, or for routine maintenance. In the simplest system, a single shut- off valve may be located at the point where the water supply enters the building
