Detail Information

High Pressure Forged Steel Trunnion Ball Valve

High-pressure forged steel ball valve is mainly used for long distance pipeline transportation of oil and natural gas and urban gas pipeline system. Due to the unique characteristics of the long distance pipeline valve, the design has fully taken into account its ability to withstand pipeline stress, as well as safety, weather resistance, long-term use of reliable sealing. 

Forged Steel Trunnion Ball Valve is usually built by 3-piece body, suitable for various kinds of pipelines, Class 150-4500 LB, PN16-PN720, JIS 5K-JIS 40K, is used to cut off or turn on the pipeline medium, can be operated by worm gear, manual, pneumatic actuator, electric driver, the connection type includes RF Flange, RTJ Flange, Butt welding, Grayloc, etc.
