Remote Control Floating Ball Valve For Water , Oil Products , Natural Gas

Floating 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.

Floating Ball Valve Structural 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. 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.

4. 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)

5. 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.

6. 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.

7. 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.

8.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.
