Which is good quality stainless steel electric ball valve

Stainless steel electric ball valve is coupled with electric actuator. The implementation of electric actuators is relatively fast, and does not require workers to personally, to a large extent, saving human resources and time.
Stainless steel electric ball valve is it has the same rotation of 90 degrees to mention the action, there are circular through-hole or passage through its axis. The ratio of the sphere to the channel should be such that when the sphere is rotated 90 degrees, the sphere should be fully spherical at the inlet and outlet to cut off the flow.
Stainless steel electric ball valve only need to rotate 90 degrees of air operation and a small turning moment can be closed tight. The completely equal body cavity provides a medium-sized, straight-through runner with low resistance. Ball valve is usually considered the most suitable for direct opening and closing use. The main features of the ball valve is its compact structure, easy operation and maintenance, suitable for general working media such as water, solvents, acids and natural gas, but also for media with bad working conditions such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be a whole, it can be combined.
The ball valve is mainly used to cut off or connect the medium in the pipeline, can also be used for fluid regulation and control, which compared with other valves, has the following advantages.
1, the fluid resistance is small, the ball valve is the smallest of all valves fluid resistance, even a reduced diameter ball valve, the fluid resistance is quite small.
2, thrust bearing to reduce stem friction torque, valve stem long-term operation can be smooth and flexible.
3, the valve seat sealing performance is good, the seal ring made of elastic material such as PTFE, the structure is easy to seal, and the ball valve sealing ability increases with the increase of medium pressure.
4, the stem seal is reliable, because the stem only fake rotary motion without lifting movements, stem packing seal is not easy to damage, and the sealing capacity increases with the media pressure increases.
5, due to PTFE and other materials with good self-lubricating, and friction loss of the ball is small, so the long service life of the ball valve.
6, Bottom stem and valve stem convex step to prevent the valve stem ejected, such as a fire caused by the stem seal damage, convex step and the body can also form a metal contact between the stem to ensure that the seal.
7, anti-static function: set the spring between the ball, stem, valve body, the static electricity generated by the switching process can be exported.
