High Pressure Ball Valves, High Temperature Ball Valves, Cryogenic Ball Valves  Production: Pressure Test,  Fire Safe Test, Low Temperature Test 

Different kinds of ball valves are suitable for different working conditions and applications.

Trunnion mounted ball valves are more suitable then floating ball valves for applicaitons with large size and high pressure.

Top entry ball valves which can be repaired on-line without removal from pipelines have advantages in maintenance than side entry ball valves.

Fully welded ball valves without leakage point are widly installed above ground or under ground in long distance Oil& Gas pipelines.

Metal seated ball valves are designed to replace soft seal ball valves for high working temperature and abrasive medium.

PFA lined ball valves are suitable for corrosive medium.

Ceramic lined ball valves are used to solve abrasion and corrosion problem together.

Cryogenic ball valves are used for applications like LNG with low working temperature.

Different kinds of ball valves also have different test. All YFL ball valves pass all the test and leave our factory with top class quality to solve problems for our customers.
