All You Need to Know About Floating Ball Valve - NTGD Valve

1. Floating Ball Valve Definition. As the name suggests, a floating ball valve uses a ball as the structure to close the cross-section of the pipe and prevent the flow of the fluid. Now, the main feature of a floating ball valve is that the ball has no structure to support it, so it stays suspended in the fluid and in place by valve seats.

What is the difference between the a floating ball valve ...

Aug 02, 2019  The floating ball valve is usually suitable for small size valves, better less than 6 inch. In contrast, the trunnion ball is fixed and supported by seat support as well as the upper lower stem. Under the medium pressure, the valve seat will move, so that the sealing ring is pressed against the ball to ensure the seal.

Flow Direction of Ball Valves - Metals Valve

The flow direction of ball valves can be either bidirectional or unidirectional depending on its seat design and working conditions. Conventional floating and trunnion mounted ball valves are usually bidirectional while some specific ball valves such as C ball valve, V port ball valve, orbit ball valve and cryogenic ball valve are unidirectional.

Valves 101: Two Types Of Ball Valves - CrossCo

A floating design ball valve sandwiches the hollow ball between two or more cupped seats that form a tight seal between the body and the ball at the inlet and outlet ports of the valve body. The ball is rotated (usually 90 degrees) by a shaft that protrudes outside of the valve body and is connected to some form of operator. For this reason, most ball valves are referred to as quarter-turn valves.

Functionality and seating technology for floating ball valves

Apr 25, 2019  A floating ball valve is a ball valve with an unsupported ball — other than the two seats it rests on — so that the ball moves in the valve cavity to help seal off the line pressure.. The key to ball valve performance is the sealing design, regardless of whether the seats are made of metal, plastic or other material. Another important function of ball valve performance is the stem seal design.
