Main Valve Function Overview:
●Installation Location: On inlet and outlet pipelines at the bottom of ground-level reservoirs or elevated
distribution tanks.
●Function: Automatically controls inflow and outflow to maintain a stable water level.
When the Water Level Is High:
●Signals from the float valve and elevation (level) pilot valve are transmitted.
●The main valve automatically closes to prevent reservoir or tank overflow.
When the Water Level Drops:
●If the inlet pressure of the main valve is higher than the static water pressure of the tank
→ water is supplied automatically.
●If the inlet pressure of the main valve is lower than the static water pressure of the tank
→ water is discharged automatically.
