Floating Ball Valve: What is it and how does it work?

A floating ball valve is a mechanical valve that controls the flow of fluid through a pipeline. It is called a “floating” ball valve because the ball in the valve is not fixed to the stem, but floats between two seats. When the valve is closed, the ball is pushed against the downstream seat to create a tight seal.

The structure of the floating ball valve consists of several parts. The housing of the valve is made of metal or other suitable material, with the ball and stem inside. The inner housing of the valve is usually made of plastic or other non-corrosive material that is resistant to chemical damage.

One of the significant advantages of the floating ball valve is that it provides a high level of sealing integrity. The valve is designed to provide a tight seal even at high pressures, making it an ideal component in pipelines used to convey corrosive or hazardous fluids.

When the valve is in the open position, the ball inside the valve rotates 90 degrees, allowing fluid to flow freely in the pipe. The ball is secured by two seats located on either side of the ball. The upstream seat holds the ball in place, while the downstream seat prevents fluid from escaping when the valve is closed.

Another advantage of the floating ball valve is that it requires minimal maintenance. The design of the valve ensures that any accumulated debris or other material is removed when the valve is closed, reducing downtime and maintenance costs.

There are different types of float valves on the market, including top entry, side entry, and split valves. The top entry valve can be easily removed for maintenance, while the side entry valve provides easy access to the ball and stem. Split valves can be bolted together for easy installation and removal for servicing.

In conclusion, the floating ball valve is a versatile and reliable valve with excellent sealing integrity and minimal maintenance requirements. They are used in a wide range of applications including pipelines handling oil, gas, water and chemical products.

If you are looking for a reliable mechanical valve that can handle high pressure fluids and resist chemical damage, consider purchasing a floating ball valve. With proper maintenance, it will last for many years, providing consistent performance and seamless fluid transfer through the tubing.
