1.Ball Float Valve
Ball float valves are the most common type of float valve. They consist of a hollow ball made of plastic or metal that floats on top of the liquid in the tank. The ball is attached to a lever arm that is connected to a valve. When the liquid level drops, the ball falls, causing the lever arm to move and open the valve. When the liquid level rises, the ball rises, causing the lever arm to move and close the valve. Ball float valves are commonly used in toilet tanks, industrial tanks, and agricultural water systems.
2.Pilot Float Valve
Pilot float valves are similar to ball float valves, but they use a smaller float that controls a pilot valve. The pilot valve then controls the main valve that regulates the flow of liquid. Pilot float valves are often used in high-pressure applications, where the force of the liquid is too great for a ball float valve to handle.
3.Diaphragm Float Valve
Diaphragm float valves use a flexible diaphragm that is connected to a lever arm and valve. As the liquid level rises, the diaphragm expands, causing the lever arm to move and close the valve. As the liquid level drops, the diaphragm contracts, causing the lever arm to move and open the valve. Diaphragm float valves are commonly used in low-pressure applications, such as in irrigation systems or small tanks.
In summary, there are three main types of float valves: ball float valves, pilot float valves, and diaphragm float valves. Each type has its own advantages and disadvantages, and the choice of which type to use depends on the specific application and the requirements of the system.
