The float valves are often referred to as a ball float. Float valves are lever-operated valves meant to regulate the level of liquids. Since float valves in Dubai are utilized in various industries and applications, the operation of float valves is entirely mechanical.
How does a float valve work?
Float valves open and close based on the liquid level that the float senses. The float could be a hollow ball made of metal or plastic. The float valves in the UAE can regulate the main valve via a sub-valve. The sub valve would establish a water level in the tank; if the water level exceeded this level, the sub valve would close, and the back pressure chamber of the main float valves would swiftly handle this pressure. Consequently, the PEX float valve in Dubai can regulate the water level in major industrial plants.
Types of float valves
Low side float valves
These float valves are predominantly utilized in flooded refrigeration units. This valve can maintain a steady level of liquid in a flooded evaporator or a connected float chamber. Therefore, if the load increases, the refrigerant will evaporate from the evaporator. The liquid level in the evaporator or the low side float level falls momentarily as a result. The liquid level will then return to normal as the float moves and helps to expand the valve opening, allowing more refrigerant to flow into the evaporator. The majority of industrial control systems utilize low-side valves.High side float valve
In the high-pressure side float valve, the float chamber is located between the condenser and evaporator on the high-pressure side. The refrigerant would evaporate and condense as the load increases. So the liquid level in the float chamber would grow. The float would increase the valve’s opening so that refrigerant could flow and the liquid level would be normal. If the liquid level is low, the opposite will occur.Direct control float valve
In direct float control, when the liquid level in the tank rises, so does the float valve. The main valve is controlled by the movement of the float valve arm unit. The float valves in Dubai consist of an integrated measurement device, controller, and final control device. The measuring instrument is the ball float.Pilot operated float valve
As the liquid level in the tank rises, the float rises to close the pilot valve. The top chamber consists of a diaphragm that closes the primary valve by applying pressure. The float falls with the level and allows liquid to pass via the float valve’s pilot line. Now, the main valve is opened so that liquid can fill the tank.
Applications of float valves
- Controlling the water level in open and closed tanks
- Condensate tanks
- The traditional toilet cistern (W.C.). It is a cyclical operation, but the ball-float valve controls the water level continuously
- Useful in a regular residential overhead tank
Advantages of float valves
- There is no need for monitoring or regulating
- Once the required water level is attained, the flow of water will be halted to prevent overflow or overfilling
- No electrical power is necessary; this is affordable. Beneficial for tank level control in distant places where there is no electricity supply
