Product Features

1. Low fluid resistance

Low fluid resistance. The fluid resistance of ball valves is the smallest among all valves, even for shrink ball valves, their flow resistance is very small.

2. Good sealing

A good sealing seat. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure.

3. Good self lubrication

Due to its excellent self-lubricating properties and low friction loss with ball valves, PTFE has a long service life for ball valves.

Advantages of flange ball valve

1. High platform design compliant with ISO5211 standard

The driver installation platform designed according to the ISO5211 standard can directly install various types of drivers, and there are two sets of PCD available for customers to choose from

2. Submerged gland design

This cover design can directly prevent leakage at the sealing position between the valve stem and valve body by locking A and the nut, without the need to disassemble the driving device, making it convenient for on-site use.

3. Design of double-layer butterfly shaped projectile device

The two butterfly shaped spring pieces that are pre compressed will compensate for the slight leakage of the valve stem, releasing the pre compressed deformation and re compressing the packing.

4. Third sealing design of valve stem O-ring

When the valve stem rotates, the "O" ring can reduce the direct friction between the valve stem and the valve body, and can also play an auxiliary role in resealing the valve stem during low-pressure use. If the pipeline medium is gas, the "O" ring has a better sealing effect than PTEE.

5. Explosion proof design of valve stem

The structural design of this valve stem and valve body can prevent the valve stem from bursting out of the valve body due to excessive pressure inside the valve chamber.

6. Design of sealing lines

Design a concentric circular positioning sealing structure between the valve body and the valve cover to prevent excess material leakage and movement when the sealing line is compressed.

7. Anti static design

By pushing the spring behind the anti-static steel ball, it is in close contact with the ball groove valve body, and the static electricity generated by the friction of the ball valve body is transmitted to the valve stem.

8. Fireproof design

When a fire occurs on site, the valve seat is burned or vaporized under the influence of high temperature, and the auxiliary metal valve seat machined from the valve body plays a sealing role.
