What Are The Characteristics Of Electric Stainless Steel Ball Valve

3 Way Ball Valve There are many types of valves in the market now, including electric, pneumatic, and dynamic ones. Here we mainly introduce electric stainless steel ball valves, which are used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Compared with other valves, electric stainless steel ball valves have the following characteristics.

1. Small fluid resistance. The ball valve has the smallest fluid resistance among all valve types. Even the reduced diameter ball valve has a very small fluid resistance;

2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time;

3. The valve seat has good sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the valve sealing ability of the ball valve increases with the increase of medium pressure;

4. The valve stem seal is reliable. Since the valve stem only rotates but does not move up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing ability increases with the increase of medium pressure;

5. Since materials such as polytetrafluoroethylene have good self-lubrication and small friction loss with the ball, the service life of the ball valve is long;

6. The bottom-mounted valve stem and the convex step of the valve stem head prevent the valve stem from spraying out. If the valve stem seal is damaged due to fire, the convex step can also form metal contact with the valve body to ensure the valve stem seal;

7. Anti-static function: A spring is set between the ball, valve stem and valve body to conduct static electricity generated during the switching process.

The electric stainless steel ball valve actuator adopts the new series GT pneumatic actuator, which has double-acting and single-acting (spring return) types, and rack and pinion transmission, which is safe and reliable; the large-diameter valve adopts the series AW pneumatic actuator fork transmission, which has a reasonable structure, large output torque, and is available in double-acting and single-acting types.
