Electric threaded stainless steel ball valve

1Electric threaded stainless steel ball valveIntroduction

It is composed of an electric actuator and a threaded ball valve. The valve body can be divided into integral, two-stage, and three-stage types. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom mounted structure with reverse sealing, and the valve stem will not be impacted when the valve chamber is abnormally pressurized. This product has stable performance and is widely used in industrial sectors such as petrochemicals, metallurgy, and power.

IIIElectric threaded stainless steel ball valveMain Features

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable. Currently, plastic is widely used as the sealing surface material for ball valves with good sealing performance, and it has also been widely used in vacuum systems.
4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.
5. Easy maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement relatively convenient.
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.
