Features of Float Control Valve
- 2. Disc fast open and slowly closed, no water hammer impact;3. Good sealing effect and long service life;4. Install at any location along with the height of the water tank and the working space.
Principle of Float Control ValveWhen the pipe supplies water from the inlet end, because the needlevalve, ball valve and float ball valve are normally open, water enters the water tank through the micro-filter, needle valve, control room, ball valve and float ball valve. At this time, there is no pressure in the control room; When the water level of the water tower rises to the set height, the ball float closes the ballfloat valve, controls the indoor water pressure rise, pushes the main valve to close and the water supply to stop. When the water level drops, thefloat controlled water valvereopens, the water pressure in the control room drops, and the main valve opens again to continue the water supply, keeping the setting height of the liquid level.
