PRODUCT INTRODUCTION:

Since the seat of the standard port fully welded ball valve is made up of a carbon teflon seal ring and a disc spring, it is adaptable to change in pressure and temperature and without leakage in the marked pressure and temperature range.Fully welded ball valves are widely used in domestic steel mills, petroleum, chemical, gas, boiler, paper, textile, pharmaceutical, food, ship, water supply and drainage, energy, polysilicon, electricity and so on.

TECHNICAL FEATURE:

1.Due to the ball valve adopt a fully-welded structure, the overall leakage point is very little which reduces the risk of leakage greatly.

2.Compact structure & easy for installation.

3.Special flux is used in welding with fine granularity and good slag removal which can meet the high strength & toughness of weld metal performance.

4.With fire-safe & anti-static device which are safer and more reliable.

5.The buried type ball valves can be directly buried into the ground, no need to build a tall valve well, only set up small shallow well on the ground, and greatly saves construction costs and engineering time.

6.Body length and stem height can be adjusted according to pipe construction & design requirements.

7.The machining precision of the sphere is very precise and easy to operate.

8.With our customer’s request, the driving device includes: lever, worm gear, electric, pneumatic, pneumatic-hydraulic, electro-hydraulic, etc.
