The pneumatic cryogenic trunnion mounted ball valve is designed specifically for applications requiring high pressure capability, low-temperature resistance, and automated operation. Compared with conventional floating ball valves, the trunnion mounted design provides superior mechanical stability, reduced operating torque, and enhanced sealing performance, making it an ideal solution for large-diameter cryogenic pipeline systems.

J-VALVES LF2M extended stem 2-piece floating ball valve is manufactured with low-temperature forged steel, PN160 high pressure rating, suitable for buried pipelines, cryogenic storage tanks and insulated piping systems. It features zero leakage, excellent low-temperature resistance and easy maintenance, widely used in oil, gas and chemical low-temperature high-pressure pipeline systems.

The C95800 top entry floating ball valve is a high-performance industrial valve designed for applications requiring excellent corrosion resistance, reliable shut-off performance, and long service life. Manufactured with Nickel Aluminum Bronze C95800, this type of floating ball valve is widely used in marine systems, offshore platforms, seawater treatment facilities, power plants, and chemical processing industries.

Cryogenic trunnion ball valves are designed for LNG, liquefied gas, and ultra-low-temperature service. They deliver reliable sealing, low operating torque, high safety, and long service life in demanding cryogenic applications.

IntroductionIn modern industrial pipeline systems, Double Block and Bleed (DBB) ball valves are widely used in applications where reliable isolation, safe maintenance, and superior sealing performance are required. Industries such as oil & gas, LNG, petrochemical, power generation, and chemical proc

Stainless steel trunnion mounted ball valves are widely used in demanding industrial applications where reliable shut-off performance, corrosion resistance, and long service life are required. Compared with conventional floating ball valves, the trunnion mounted design provides additional mechanical support for the ball, making it suitable for large diameter pipelines, high pressure systems, and critical process applications.

In modern oil & gas, petrochemical, LNG, power generation, and process industries, Double Block and Bleed (DBB) Ball Valves play an important role in achieving safe isolation, maintenance efficiency, and reliable pipeline operation. Selecting the correct seat design is one of the most critical factors affecting valve performance.
