Electric flange ball valve is a kind of rotary 90 ° rotary class ball valves, with excellent sealing performance, large flow capacity, flow resistance coefficient is small, simple structure, easy maintenance, long service life and so on. Its valve body channel and connecting pipe diameter is equal and into a diameter, the medium can flow through almost no loss, with electric actuators, the product is usually used for sealing the strict requirements of the occasion, in addition to the control of gases, liquids, steam media, but also suitable for controlling water containing fiber impurities in the medium. Widely used in petroleum, chemical industry, metallurgy, light industry, papermaking, power station, refrigeration and other fields of work.
Product Features
- Fluid resistance is small, ball valves are one of the smaller fluid resistance of all valve types. Even the reduced diameter ball valve, its fluid resistance is quite small.
- Thrust bearings reduce the friction torque on the valve stem, ensuring long-term balanced and flexible operation.
- The valve seat exhibits excellent sealing performance, utilizing sealing rings made of materials such as polytetrafluoroethylene (PTFE). Its structure facilitates effective sealing, and the sealing capability of the ball valve increases with rising medium pressure.
- The valve stem seal is reliable. Since the valve stem only rotates without vertical movement, the packing seal is less prone to damage and its sealing capability increases with rising medium pressure.
- Due to the excellent self-lubricating properties of materials such as polytetrafluoroethylene, friction losses with the ball are minimal, resulting in a longer service life for ball valves.
- The bottom-mounted valve stem and the raised shoulder on the stem head prevent stem ejection. Should fire damage compromise the stem seal, the raised shoulder can form a metal-to-metal contact with the valve body, ensuring stem sealing integrity.
