Coosai Top entry ball valves will make the online maintenance easy and no need to dismantle the body from the pipes.

Coosai top entry ball valve has special patent in design.



Design Feature

1: Full bore or reduced bore

2: Integral body structure

3: Double Block & Bleed, Double isolation and bleed(DIB-1&DIB-2)

4: Fire safe design(API 607)

5: Blowout-proof system

6: Anti-static design

7: Self cavity relief

8: Fugitive emission testing(optional)

The ball is fixed by trunnion and stem for size 4” &smaller. Trunnion plate support for size 6” & larger


Blow-out proof stem:

The stem is made separately from the ball with integral T-type round shoulder, retained by bland .(other designs are Available on request)


Anti-static device:

Spring plus graphite type anti-static device are applied between the ball ,stem, gland Flange and body to keep the electrical Continuity between all the metallic components.

And ensure the resistance lower than the most severe service requirement.


Sealing Options

Soft seat: Metal to Metal O-Ring seal

Simple structure reliable sealing Applicable to particulate Reliable sealing low torque meet customers' high wide application low cost.

Media conditions sealing reliability and low torque requirements.




Fire safe design

Coosai ball valves ensures 100% pass of the fire safe test. As Coosai Ball valve applies two sealed design via O-ring seals and metal graphite spiral wound gasket. When the valve is on fire, non-metallic materials such as PTFE seat seals, gaskets ,O-ring seals,rubber etc will be damaged, meanwhile the outer layer of metal graphite spiral wound gasket provides a secondary seal. When the soft seat is burned, metal seat will automatically form a metal seal with ball under the urging of the spring which will effectively control the internal leakage and external leakage. Valve design fully accords with API 607, API 6FA, BS 6755, JB / T 6899 and other standards.





Double piston effect seat, medium pressure, both upstream and downstream as well as in the body cavity, creates a resultant thrust that pushes the seat ring against the ball, valve with double piston effect seat rings require a cavity pressure relief to reduce the build-up of over pressure in the body cavity.
