ZONE CONTROL VALVE

Zone Control Valve is a system designed to separate the area in case of maintenance and to get the indication of fire zone on a combination of butterfly valve, flow switch, pressure gauge, and Test & Drain valves.

Zone control valve (floor control valve) is a combined unit of 4 parts: signal butterfly valve, water flow indicator, pressure gauge, and test & drain valve.

They are assembled on a fire pipeline to separate the fire area into a small distribution zone for indication and control. Because of fire sprinkler or test valve activation, the indicator detects water flow and transmits a signal to the control system. After fire suppression, the butterfly valve gets a signal to indicate manual shutdown down the water flow to recover the system
