What is A Float Valve ?

- The float valve is a simple mechanical liquid level controller. A float detects changes of elevation in the liquid free surface and opens or closes a valve accordingly.

- This valve can be used to control the water level in a tank, this valve is capable to open and close itself as the liquid level changes. A float is used to mechanically operate this valve.

- These valves are liquid level control valves and they are mostly used in the industrial refrigeration system. In a large refrigeration system, the float valves are used as a throttling device. Float valves are actuated lever valves that are designed to control the level of the liquids.

Types of Float Valve

• Mechanical Float Valve

• Hydraulically Operated Float Valve

• Electric Operated Float Valve

- Electric float valves work in partnership with a sensory float in the tank/reservoir to fully open or close the valve to restrict the water flow. The electrical level sensor detects the level in the liquid supply and opens or closes the valve depending on the detected level. See the electric float valves that Bermad offers below.

• Float Valve with Operated Ball

Key Features of Float Valve

- It is simple structure, easy to use

- Easy to install and maintain

- No sound when operating

- Reasonable price and not too high

- It is easy to get stuck in the membrane and clog the valve when using an unclean water source

- Clean and maintain the valve periodically to increase the service life of the valve
