Electric flange ball valve advantages

Electric flange ball valve is ball valve with electric actuator. The execution speed of the electric actuator is relatively fast, and workers are not required to do it personally, which saves human resources and time to a great extent. Electric flanged ball valve is it has the same rotation 90 degree lift action, there are circular through holes or channels through its axis. The ratio of the sphere to the opening should be such that when the ball is rotated 90 degrees, the sphere should be present at both the inlet and outlet to cut off the flow.

Electric flanged ball valve is mainly used to truncate or connect the medium in the pipeline, can also be used for fluid regulation and control, compared with other valves, has the following advantages:

1, small fluid resistance, ball valve is one of the least fluid resistance of all valves, even reduced diameter ball valve, its fluid resistance is quite small.

2, thrust bearing reduce stem friction torque, can make the stem long-term operation smooth and flexible.

3, the valve seat sealing performance is good, the sealing ring made of ptfe and other elastic materials, the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of medium pressure.

4, the valve stem seal is reliable, because the valve stem only as if rotating without lifting movement, the packing seal of the valve stem is not easy to damage, and the sealing capacity increases with the pressure of the medium.

5, because ptfe and other materials have good self-lubrication, friction loss with the ball is small, so the service life of ball valve is long.

6, lower mounted stem and stem head convex order to prevent stem ejection, such as fire caused by stem seal damage, convex order and valve body can also form metal contact, to ensure stem seal.

7, anti-static function: set spring between the ball, stem, valve body, can switch the process of electrostatic export.
