Electric flange ball valveIt is a type of 90° rotationball valvesThe valve is characterized by excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, easy maintenance and long service life. Its valve body channel and connecting pipe diameter is equal and into a diameter, the medium can flow through almost no loss. Equipped with electric actuator, the product is usually used for sealing the strict requirements of the occasion, in addition to the control of gas, liquid, steam medium, 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 work areas.
Product Features
- Low fluid resistance, ball valves are one of the lower fluid resistance of all valve types. Even ifReducing Ball ValveThe fluid resistance is also quite low.
- Thrust shaft bearings reduce stem friction torque, allowing the stem to operate in a balanced and flexible manner for long periods of time.
- Seat sealing performance is good, the use of polytetrafluoroethylene and other materials made of sealing ring, the structure is easy to seal, and the sealing capacity of the ball valve with the increase in media pressure and increase.
- Valve stem sealing is reliable, because the valve stem only rotates without lifting movement, the packing seal of the valve stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium.
- As materials such as PTFE have good self-lubrication, the friction loss with the ball is small, and the service life of the ball valve is longer.
- The downward-mounted stem and stem head boss prevent stem blowout, and if a fire destroys the stem seal, the boss forms a metal contact with the valve body to ensure stem sealing.
