What are the features of Trunnion Mounted Ball Valve?



As we know,we can divide ball valve into floating type and trunnion mounted type.

It will depend on their setting pressure and customer’s request.

Trunnion mounted ball valve is a new generation of high-performance ball valve, which is suitable for long-distance pipeline and general industrial pipeline. Its strength, safety and resistance to harsh environment are specially considered in the design, and it is suitable for various corrosive and non corrosive media.


So what are the features of trunnion mounted ball valve?


1. Double block and discharge function: trunnion mounted ball valve adopts spring pre tightened floating valve seat. When the valve is in full open or closed state, the valve seat at upstream and downstream sides blocks the flow, and the retention in the middle cavity of the valve body is discharged through the discharge valve.

2. Automatic pressure relief function: when the temperature of the retention medium in the valve body cavity rises and causes abnormal pressure rise, it is not necessary to pass through the safety valve, but only rely on the valve seat function to automatically relieve pressure, which is very important to ensure the safety of the valve when conveying liquid medium.

3. Fire safety structure: all valves have fire safety function, and their design and manufacture comply with API607 and API6FA specifications.
