With the increasing demand for LNG and cryogenic energy systems, valves must provide reliable sealing performance under extremely low temperatures. The Cryogenic DBB Ball Valve is specially designed for these applications, combining double block and bleed functionality with advanced cryogenic design features to ensure safe operation.

J-VALVES specializes in manufacturing high-performance trunnion mounted ball valves designed according to international standards, providing reliable solutions for oil, gas, LNG, chemical, and industrial pipeline systems.

For harsh oil & gas working conditions, API 6D certified 2‑piece floating ball valve outperforms standard ball valves in sealing performance, pressure resistance, fire‑safe & anti‑static features, long‑term reliability. Ideal for oil‑gas transmission and pipeline station projects.

Designed with double block and bleed functionality, DBB ball valves provide two independent sealing barriers with a bleed system between them, allowing operators to verify isolation integrity before maintenance or equipment intervention. This design has become a preferred solution for offshore production platforms, FPSO systems, subsea applications, and oil and gas processing facilities.

As a professional cryogenic trunnion ball valve manufacturer, J-VALVES owns independent machining workshops, assembly lines and cryogenic test benches. LF2M cryogenic ball valves pass liquid nitrogen tests conforming to API598 & BS6364. Third-party witnessed cryogenic testing is available.

For seawater, offshore, and corrosive industrial systems, material selection is essential for valve reliability. The C95800 Floating Ball Valve uses Nickel Aluminum Bronze (NAB) material, providing excellent corrosion resistance, mechanical strength, and long service life in demanding environments.

Founded in 2009, J-VALVES is a direct manufacturer of industrial floating ball valves. We accept bulk orders of carbon steel & stainless steel floating ball valves with strict testing. Stable supplier for global engineering projects.

In automated pipeline systems, selecting the correct actuator is essential for the reliable operation of a Double Block and Bleed Ball Valve. The actuator must provide sufficient torque, accurate control, and stable performance under different operating conditions.

In high-pressure and critical pipeline applications, valve stability and sealing reliability are essential for safe operation. The Trunnion Mounted Ball Valve is widely used in oil & gas, petrochemical, LNG, and industrial systems due to its robust structure, low operating torque, and excellent pressure resistance.
