What is a Float Valve and How Does it Work?

A float valve can be used for various purposes. Water level in a tank can be controlled by these walls and they open and close automatically as the water level changes. For mechanically operating the valve the float plays a major role. These valves are mostly used in industrial refrigeration system and control the liquid level. They can be used as a throttling device in many large refrigeration systems. Float valves contain level levels and are designed in such a manner so that they could effectively control the liquid levels. Torbeck valve is a good choice if you are looking for an excellent purchase.

Uses of float valve

  • In order to prevent overflow and maintain proper water level in water tanks and cisterns these valves are used.
  • When the ball rises or falls that shows the control level of the valve and is controlled in such manner.
  • If you need valves for low, medium or high pressure applications then Torbeck valves are a great choice.
  • In large refrigeration systems these float valves can be used as a throttling device.

How does it Work?

These valves can be used in combination with other valves and are used widely in a variety of industrial applications. When it senses the liquid level with the help of the float it open and closes accordingly. It could be a hollow, metal or plastic ball. It is used as a flow pressure reducing valve as well. The main valve can be controlled by using a sub valve. The sub valve helps monitor water level and it sets a certain standard for the liquid level,  the liquid exceeds the level the valve closes and as a result the main valve will help handle this pressure as quickly as possible. Therefore the float valve can be used to control and monitor the water level in various industries. Torbeck valve is a good choice for many applications.

How to Choose?

If you are confused about which float valve to purchase then consider and check for a few factors before making your purchase.

  1. Check the size of the float valve and choose which one best suits your requirements.
  2. Look for the connections.
  3. Check for the angle and patterns.
  4. You should select a float valve that give maximum operating pressure.
  5. Check for the discharge pressure of the valve and how much pressure it can take.
  6. Finally you must check for its temperature, maximum temperature is preferred.


The float poles in the float valves are comprised of metal, treated steel, or stirred line. The trim in the valve, principle valve, and the seat is comprised of tempered steel. Turn connector, vertical activity of the float rod, supplant rosette, and joins the switch and float rod. Teflon is utilized in the circles and cups for high-temperature purposes. Plan contemplations incorporate giving high stream rates at a low head misfortune. By appropriately planning the valve seat cavitation and commotion can be limited, limit frictional opposition, and shut-off loads, and guaranteeing the float. These valves are intended to steer worked or standard, with little and enormous holes, long switches, little buoys, or short switches. To get a legitimate valve life, the float valves should not be exaggerated as far as stream or pressing factor.
