Electric flanged ball valve

Product features

1, fluid resistance is small

Low fluid resistance. Ball valves have the lowest flow resistance of any valve, with minimal flow resistance even for shrink valves.

2, good sealing

Good sealing seat. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing capacity of ball valves increases with the increase of medium pressure.

3, good self-lubrication

Because PTFE has good self-lubrication characteristics, friction loss with ball valve is small, ball valve service life is long.

Flange ball valve advantages

1. High platform design in accordance with ISO5211 standard

The driver installation platform designed according to ISO5211 standard can be directly installed with all kinds of drives, and there are two sets of PCDS for customers to choose from

2. Sunken gland design

The gland design prevents leakage in the stem and body sealing position by locking A and nut directly without removing the drive for field use.

3, double butterfly shrapnel device design

Two pre - pressed butterfly shrapnel in the stem of micro leakage will play a compensation role, release the deformation of the pre - compressed packing again.

4, stem "O" ring third re-seal design

The "O" ring reduces direct friction between the stem and the body as the stem rotates and assists in stem re-sealing at low pressure. If the pipe medium is gas, the "O" ring provides a better seal than the PTEE.

5, valve stem explosion-proof design

The structure design of stem and valve body can prevent stem from rushing out of valve body due to high pressure in valve chamber.

6, the design of sealing lines

A concentric circular positioning seal is designed between the valve body and the bonnet to prevent leakage and movement of excess material when the sealing lines are squeezed.

7, anti-static design

Through the push of the spring behind the anti-static steel ball, make it close contact with the ball groove body, the static electricity of the ball body friction to the valve stem.

8. Fire prevention design

When the scene of fire, seat burnt or vaporized under the influence of high temperature, processed from the valve body of the auxiliary metal seat, play a sealing role.
