Reliable isolation and sealing are critical in oil & gas, LNG, and petrochemical pipelines. J-VALVES DBB (Double Block and Bleed) Ball Valves deliver high-performance sealing, operational safety, and compliance with API 6D, API 608, API 598, and ASME B16.34 standards. Their advanced seat designs provide exceptional leak-tight performance in demanding industrial applications.

J-VALVES top entry floating ball valves offer three core advantages: precision manufacturing, inline maintenance, and corrosion-resistant materials. Delivering full-chain assurance from workshop to site for oil, gas, and marine engineering.

Featuring trunnion support structure, forged construction and full-process quality control, J-VALVES trunnion mounted ball valves deliver zero-leakage sealing and long service life for high-pressure, large-bore working conditions. We provide efficient fluid control solutions for oil, chemical and energy industries with a wealth of successful international project cases.

J-VALVES pneumatic trunnion ball valves, A105N forged carbon steel, API 6D certified, bidirectional sealing, low-torque pneumatic actuator, for oil, chemical, power industries.

In the oil and gas industry, ensuring reliable flow control, isolation, and corrosion resistance is essential for pipeline safety and efficiency. C95800 Floating Ball Valves have emerged as a preferred solution for pipelines handling seawater, crude oil, refined products, and other corrosive fluids. Constructed from C95800 Nickel Aluminum Bronze (NAB), these valves combine high mechanical strength with superior corrosion resistance, making them ideal for long-term service in harsh environments.

J-VALVES 3PC butt weld trunnion ball valve solves high-pressure challenges in oil, chemical and natural gas industries with in-line maintenance, zero-leakage sealing and customized design, cutting operational & maintenance costs and enhancing overall system stability.

In critical industrial pipelines, reliable isolation is essential to ensure safety, protect equipment, and enable maintenance without shutting down entire systems. The Double Block and Bleed (DBB) Ball Valve provides this solution by combining two sealing mechanisms with a bleed port, offering safe depressurization and enhanced operational security.J-VALVES has specialized in manufacturing DBB ball valves since 2009, delivering durable, API- and ASME-compliant solutions for global oil & gas, LNG, petrochemical, offshore, and power generation projects.

As the demand for LNG, industrial gases, and cryogenic processing continues to grow, valve performance in low-temperature environments has become increasingly important. The Low Temperature Carbon Steel Trunnion Mounted Ball Valve is specifically designed to provide safe, reliable, and long-lasting flow control in cryogenic applications where conventional valves may struggle to maintain sealing integrity and operational stability.
