pneumatic v type ball valve -凯发彩票

electric flange ball valve is a rotation of 90° valve, good sealing performance, flow coefficient, flow resistance coefficient is small, simple structure, long service life, easy to repair.equipped with electric cylinder actuator.

product features:

1. electric flange ball valve fluid resistance is small, ball valve is a kind of small fluid resistance in all valves, even if the diameter of the ball valve, its fluid resistance is also quite small.

2. the ball valve thrust bearing reduces the friction torque of the valve stem and enables the stem to operate in a balanced and flexible way in the long run.

3. the seat sealing performance is good, using ptfe and other materials made of sealing ring, the structure is easy to seal, and the sealing ability of the ball valve increases with the addition of medium pressure.

4. valve stem seal is reliable, because the stem only rotation movement and do not do up and down movement, valve stem packing seal is not easy to destroy, and the sealing ability increases with the pressure of the medium added.

5. due to the good self-lubricity of ptfe and other materials, the friction loss with the ball is small and the service life is long.

6. lower mounted stem and stem head convex steps prevent the stem from gushing out. if the stem seal is damaged by fire, the convex steps and the valve body can also form metal contact to ensure the stem seal.

7. electric flange ball valve has excellent sealing performance, large flow coefficient, small flow resistance coefficient, simple structure, long service life and easy maintenance.
