Explosion Proof Stainless Steel Electric Flange Ball Valve 90°
Rotary Ball Valve
Flange Electric Ball Valve Introduction
The electric flange ball valve is a 90° rotary ball valve. Its
valve body channel aligns with the pipe diameter, creating a
consistent diameter that allows the medium to flow through without
any loss. This valve is ideal for applications requiring a high
level of sealing precision. It can control gases, liquids, steam,
as well as sewage and media containing fibrous impurities. The
electric flange ball valve is widely utilized in industries such as
petroleum, chemical processing, metallurgy, light manufacturing,
papermaking, power plants, refrigeration, and more.
Product Features
1. Small fluid resistance. Ball valve has the smallest fluid
resistance among all valve types. Even for reduced diameter ball
valve, its fluid resistance is quite small.
2. Good valve seat sealing performance. The sealing ring made of
materials such as polytetrafluoroethylene is easy to seal, and the
valve sealing ability of the ball valve increases with the increase
of medium pressure.
3. Reliable valve stem sealing. Since the valve stem only rotates
but does not lift, the packing seal of the valve stem is not easy
to be damaged, and the sealing ability increases with the pressure
of the medium.
4. Since polytetrafluoroethylene material has good self-lubrication
and small friction with the ball valve, the service life of the
ball valve is long.
