Component specification:
Zone control valve (Floor control valve) is a combined unit of 4 parts: signal butterfly valve, waterflow indicator, pressure gauge and test & drain valve.
They are assembled on fire pipeline to separates the fire area into small distribution zone for indication and control. Because of fire sprinkler or test valve activation, the indicator detects water flow and transmits signal to control system. After fire suppression, butterfly valve gets signal, to indicate manual shut down the water flow for recovering the system.
