Automatic Trunnion Mounted Ball Valve , 2 Way Floating Ball Check Valve

Trunnion Mounted Ball Valve Brief introduction:

Trunnion Mounted ball valves mainly used in the industries of natural gas, oil products, chemicals,

metallurgy, urban construction, environmental protection, pharmaceuticals, foodstuff and etc.

Among them, the sulfurresisting series products are applicable for seriously corrosive natural gas

pipeline containing hydrogen sulphide mediums and impurities.

Trunnion Mounted Ball Valve features:

1. Distinctive seating structure

according to the extent of pressure, medium properties and sealing requirements, fixed ball valve

may be made to front seal structure, back structure, or front-back dual seal structure.

2. Self-relieving structure

In case of abnormal rise of pressure at middle cavity, ball valve of single seal structure is provided

with selfrelieving function, while ball valve of dual seal structure uses the auxiliary pressure relief

device on valve body to carry out pressure relief.

3. First aid of seal

the valve designed with an auxiliary Seating emergency seal system, as shown in the figure. In case

of soft seal damaged, or failure of seal in an emergency circumstance, emergency seal may be

effected by injecting in sealant through auxiliary sealing system. If needed, emergency seal assembly

can be used to rinse and lubricate the seating area. Plus, valve system can also be designed with an

auxiliary emergency sealing system.

4. Fire protection structure

If requested by working conditions and users, ball valve may be designed to fireproof. The fireproofing

design of ball valve is to the standards of API 607 and JB/T6899. In case of soft seal ring burnt in fire,

the fire protection structure of ball valve functions to prevent mediums from mass leakage, thus to avoid

fire spreading.

5. Antistatic structure

when operating the valve, the friction between the ball and seat will produce electrostatic charge that

can be accumulated on the ball. To prevent static spark, an antistatic device is placed on the valve to

derive the electric charge accumulated on the ball(as show in the figure)

6. Lock device

To prevent misoperation and the unexpected open or closed caused by the unpredicted circuit vibration,

a locking device is designed at the fully opened and closed positions of hand operated ball valve. This

design is proven especially good and effective in the production line of inflammable mediums of petroleum

and chemicals, or when valves are mounted outdoors.

7. Full and reduced bores structure

To meet the different requirements of users, we have full and reduced bore valves series(as shown in

the figure). The inside diameter of full-bore series ball valve is comparatively lighter in weight, but

its fluid resistance is only 1/7 of that of globe valve of the same caliber. So, reduced-bore ball valves

boast of broader prospects.

8. Discharge device on valve body

If requested by users or by the system, discharge valve may be mounted on the body of ball valve. In

case the two ends of valve have been sealed, the pressure in valve will be released through the

discharge valve on the body. Besides the function of DBB, this discharge valve also functions to rinse

and blow out the deposits inside valve body.

9. Corrosion resistance

corrosion allowance is left for the design of body thickness, the stem, fixed shaft, ball, seat and bottom

cover of carbon steel valve are all chemical plated in surface to ASTM B733 and B656. Use of paint from

international co. to deal with all kinds of conditions.

10.Sulfide stress cracking resistance

the materials exposed to fluid of our sulfur resisting ball valves, including fastening components, are all

selected to NACE MR0175. Rigorous quality control and inspection is implemented in the manufacturing

process to make our products conformed to the standard and suitable for vulcanizing conditions.

11. Extension bar device

extension device may be provided for buried ball valve, which include the extension of valve stem,

greasing valve and discharge valve. As shown in the figure, users shall specify the requirements and

length to be extended(the length is generally the distance from the center of valve channel to the

center of operating device).
