Product overview

Body joint is fully welded that eliminates external leakage through body joint. The valves are specially suitable for long distance buried pipelines with rigorous service conditions, such as city gas, city heating, petrochemical plants and etc.


The main structure features include:

1.Flow resistance is small;

2.Piston seat, fire safe, antistatic design;

3.No limitation on the flow direction;

4.When valve is in full open position, seat surfaces are outside flow stream that always in full contact with gate that can protect seat surfaces, and suitable for pigging pipeline;

5.Spring loaded packing can be chosen;

6.Low emission packing can be chosen according to ISO 15848 requirement;

7.Stem extended design can be chosen;

8.Metal to metal seat design can be chosen;

9.DBB,DIB-1,DIB-2 structure can be chosen;

10.The ball is fixed with a supporting plate and a fixed shaft;

11.Single welding joint or double welding joint design can be chosen.
