Trunnion Mounted ball valve are suitable for using on various kinds of pipelines of Class 150 to Class 2500, PN16~PN160, JIS 10K~ JIS 20K to cut off or turn on the pipeline medium, of which the operation types include worm gear, manul, pneumactic or electric actuators, being in general of flange connection, and butt welding end connection as well.

 

DOUBLE ISOLATION & BLEED (DIB)

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.

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 BLOCK & BLEED (DBB)

When the ball is in the closed position, each seat seals off the process medium independently at the same time between the up/down stream and body cavity, it allows bleeding the trapped cavity pressure (DBB) through drain and vent valve. The double block and bleed function make it possible to flush the valve under pressure and verify that the seat are sealing properly.
