Features of Duplex Steel Ball Valves


The dual-phase steel ball valve uses a top-loading structure design. This design will reduce the connection bolts of the valve body itself under the conditions of large diameter and high pressure, enhance the reliability of the valve and overcome the influence of the system weight on the normal operation of the valve. . The ball of the dual-phase steel ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end. The following will share with you the characteristics of six dual-phase steel ball valves:
one,The ball valve channel is flat and smooth, and it is not easy to deposit media, and it can be pigged through the ball.
2. The switch is fast and convenient, as long as the valve body rotates 90°, the ball valve will complete the full opening or full closing action, and it is easy to realize rapid opening and closing.
three,The flow resistance is small, and the ball valve is the one with the smallest fluent resistance among all valves. Even the reduced diameter ball valve has a relatively small fluid resistance.
Four,The opening and closing of the dual-phase steel ball valve only makes a 90° movement, so it is easy to realize automatic control and remote control. The ball valve can be equipped with electric devices, pneumatic devices, and hydraulic devices.
five,Stem sealing is reliable. When the ball valve is opened and closed, the valve stem only rotates 90°, so the packing seal of the valve stem is not easy to be damaged, and the reverse sealing force of the valve stem increases with the increase of the medium pressure.
six,Good sealing performance. The ball valve seat (sealing ring) is generally made of elastic materials such as polytetrafluoroethylene, which is easy to ensure the sealing, and the sealing force of the ball valve increases with the increase of the medium pressure.

The above six points are the full content of the characteristics of the dual-phase steel ball valve. After reading it in detail, it will definitely be of great help. Collect it and forward it~
