In the choice of flange ball valve to understand what

- Dec 14, 2017 -

It is a kind of ball valve flange ball valve structure is novel, but sold on the market of the flange ball valve manufacturers, so in the selection in the factory when to understand what it is, flange ball valve has some superiority own unique structure, such as the switch without friction, the seal is not easy to wear, opening and closing moments. This reduces the specifications of the actuators. With the multi rotation electric actuator, the medium can be adjusted and cut off. Therefore, in the selection of flange ball valve manufacturers need to understand its structural characteristics, as follows:

1, open and close without friction. This function completely solves the problem that the traditional [wiki] valve [/wiki] affects the seal because of the friction between the cover and the cover.

2, low torque design. The stem of the special structure design only needs a small hand to open and close the valve easily.

3, single seat design. It eliminates the problem that the medium of the valve in the valve is safe to use because of the abnormal rising of pressure.

4. The installed structure. The valve installed on the pipe can be checked and repaired online directly, which can effectively reduce the stop of the device and reduce the cost.

5. The self cleaning structure of the sealing surface. When the ball leans away from the valve seat, the fluid in the pipeline passes through the ball's close cover to 360 degrees, which not only eliminates the local scour of the high speed fluid to the valve seat, but also washes away the accumulation on the sealing surface to achieve the purpose of self cleaning.

6. The wedge-shaped seal structure. The valve is controlled by the mechanical force provided by the stem, and the ball wedge is pressed to the valve seat and sealed, so that the sealing property of the valve is not influenced by the pressure difference of the pipeline. Under various working conditions, the sealing performance is guaranteed reliably.
