Do you want to know the characteristics and advantages of trunnion mounted ball valve?

The following is an outline：

1.The characteristics of the trunnion ball valve

2.The advantages of trunnion type ball valve

A. The characteristics of the trunnion ball valve:

1. Double sealing and discharging function: The trunnion mounted ball valve adopts a spring pre-loaded floating valve seat. When the industial valve is in the fully open or fully closed state, the upstream and downstream side seats block fluid and the valve body retentate is discharged through the discharge valve.

2, Automatic pressure relief function: the valve body cavity to maintain the abnormal temperature caused by the abnormal temperature rise of the medium, do not need to pass the safety valve, only rely on the valve seat function can automatically relieve pressure, thus ensuring the safety of the valve when transporting liquid medium is very important.

3, Fire safety structure: the industrial ball valve has fire safety function, its design, manufacture follows the requirements of API 607 and API 6FA specifications.

B.The advantages of trunnion type ball valve:

1, Sealed emergency grease injection rescue: due to foreign matter or fire in the medium, the seat seal accidental failure, the grease injection valve can be quickly connected with the grease gun, the imported pump can quickly and conveniently inject the sealing grease into the valve seat sealing part. Reduce leakage.

2, Reliable stem seal and low operating torque: In addition to the standard sealing gasket, an O-ring is also installed on the sealing gland. The double seal ensures the reliability of the stem seal; additional graphite packing and seal grease injection minimizes stem leakage after a fire. Stem and thrust bearings make the valve easy to operate.

3, Full diameter or reduced diameter: use full diameter or reduced diameter structure as needed. The full-diameter valve flow hole is the same as the inner diameter of the pipe, making it easy to clean the pipe.

4, The valve stem can be lengthened: according to the installation or operation needs, the valve stem can be stretched. Extended ball valves are especially suitable for applications where underground piping (such as city gas) is required. The size of the extension rod is determined according to customer needs.

5. Flexible operation: The valve seat and stem bearing with small friction coefficient and good self-lubricating performance greatly reduce the working torque of the valve. Therefore, the valve can operate freely for a long time even if the sealing grease is not provided.
