Products Description
The A216 WCB floating ball valve is an important type of valve widely used in petrochemical, long-distance pipeline, and other fields. The closing element of the A216 WCB floating ball valve is a perforated ball (or part of a ball). The ball rotates with the valve stem, opening or closing the valve.
Among various valves, ball valves have relatively low flow resistance. When a full-bore ball valve is open, the ball passage, valve body passage, and connecting pipe diameter are equal and form a single diameter, allowing the medium to flow through with almost no loss.
The A216 WCB floating ball valve can be fully opened or closed with a 90° rotation, providing rapid opening and closing. Compared to gate valves and globe valves of the same specifications, ball valves are smaller and lighter, facilitating pipeline installation.
