Control Float Valve

Control Float Valves is a device installed in pipelines that regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. It is used to control the liquid level of water tower and reservoir, etc. It maintains a preset water level in a reservoir or a water tank.

Control Float Valve consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level has risen to a preset fill line, the float forces the lever to close the valve and shut off the water flow. It is fitted with a float designed to control the top water level in the tank. A dual level float can be fitted to control the level between top and bottom levels.  Control float valves can be remotely operated with an addition of a solenoid or a hydraulic relay.

Control Float Valves have many advantages, such as easy maintenance, flexibility, durability, accurate control of liquid level, water level not affected by hydraulic pressure, leak-tightness upon closing. It may be seperately mounted from main valve body.
Control Float Valves are applicable to many fields, like chemistry, petroleum, gas, metallurgy, and the badly corroded long distance pipelines of natural gas with a lot of impurities.
