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.

J-VALVES factory-made 3PC flanged trunnion ball valve with API6D & API607 certification, forged steel, stainless steel and LF2 cryogenic options. Check our core manufacturing strengths and real projects in Saudi, China and Australia, custom valve with wooden export packing.

J-VALVES supplies custom electric cryogenic extended stem fully welded ball valve for -196℃ LNG, LOX, LIN service, compliant with API6D BS6364, explosion-proof electric actuator & customizable stem length, factory founded in 2009 for cryogenic valve solutions.

In modern industrial fluid control systems, high-pressure, high-temperature and highly corrosive environments impose stringent requirements on valve performance. The 6” 600LB A105 trunnion mounted ball valve with gear operator has become one of the preferred valves for petrochemical engineering, natural gas transmission and large-scale industrial process systems due to its outstanding pressure resistance, reliability and ease of operation.

J-VALVES 2PC trunnion mounted ball valve core advantages, WCB Class150 two piece fixed ball valve with API6D & API6FA certification, customized reduced bore 12×10” trunnion ball valve for global oil & petrochemical EPC projects.

As the global demand for cleaner energy continues to grow, Liquefied Natural Gas (LNG) has become an important fuel source for power generation, industrial processes, and transportation. LNG storage and transportation systems operate under extremely low temperatures, requiring equipment that can provide reliable isolation, leak prevention, and operational safety.

Floating ball valves are widely used in industrial piping systems for on/off control due to their simple design, reliable sealing, and ease of operation. One of the most critical factors influencing valve performance is the seat material. In industrial applications, floating ball valves are commonly offered with soft seats or metal seats, each with distinct advantages and limitations.
