The trunnion-mounted side entry ball valve is the preferred design for oil and gas applications. The ball is supported on a fixed vertical axis, allowing free rotation while maintaining alignment. Sealing is achieved through pressure- and spring-energized seats. Smaller sizes feature a single trunnion support, while larger sizes use reinforced trunnion plates. Valves are designed to comply with leading international standards and applicable customer specifications. Available body materials include carbon steel, stainless steel, duplex stainless steel, and a full range of exotic alloys. Multiple body seal and seat solutions are offered, including metal-to-metal seal rings.
