Forged steel ball valves are mainly used for long-distance pipeline transportation of oil and natural gas and urban gas pipeline systems. Due to the unique characteristics of the valves for long-distance pipelines, the ability to withstand pipeline stress, safety, weather resistance, and long-term reliability have been fully considered in the design; the sealing and structural design are unique to the stunt company. The operation modes include manual-worm gear drive, pneumatic, electric, gas-liquid linkage, electro-hydraulic linkage, and various special control forms.

 Functional characteristics of forged steel ball valve

1. Double cutoff and discharge

2. Safe decompression

3. Reliable sealing

4. Fire protection design

5. Cleaning the pipeline

6. Emergency seal

7. Special valve

8. Valve cover combination seal

9. Sewage

10. Lengthened stem

11. Anti-static design

12. Safe to withstand pipeline stress

 The main design features are:

1. Full diameter / reduced diameter;

2.90 degree positioning and lock structure;

3. Special form "Y" head handle;

4. Fire protection and anti-static design;

5. A pair of opposed butterfly springs;

6. Anti-blowing stem;

7. Double sealing structure in the middle of the valve stem;

8. Bolt and thread gasket seal the bonnet.

Valve installation:

     The installation of the valve is the same as the installation of other mechanical equipment. There is a problem with the installation attitude. The correct installation attitude of the valve should be that the internal structure conforms to the flow direction of the medium, and the installation attitude meets the specific requirements and operation requirements of the valve structure. In addition, the correct posture contains a sense of uniformity and beauty. It is an organic combination of technicality and artistry in modern art modeling.
