View DetailsHigh-Pressure Trunnion Mounted Ball Valve Kunjian Tech’s High-Pressure Trunnion Mounted Ball Valve is engineered for high-performance flow control in demanding B2B environments, including oil and gas pipelines, petrochemical plants, and power generation. Designed for durability and safety, our trunnion valves ensure reliable shut-off under extreme pressure conditions while minimizing operational costs. Key Features & Benefits: Features a fixed-ball design with floating, spring-loaded seats to ensure a bubble-tight seal at both high and low pressures. The trunnion-mounted stems absorb line pressure, reducing friction and allowing for easy operation and smaller, more cost-effective actuators. Provides independent upstream and downstream sealing, allowing for safe cavity venting and isolation. Built to industry standards including API 6D, featuring fire-safe designs (API 607) and anti-blowout stems. Available in high-grade carbon steel, stainless steel, and duplex alloys to withstand corrosive and abrasive media. Technical Specifications: Size Range: 2” to 48” Pressure Class: ANSI 150# to 2500# Body Material: A105N, LF2, F316, F51, and more. Seat Options: Soft seat (PTFE/PEEK) or Metal-to-Metal for high-temperature service. Enhance your pipeline safety and efficiency with Kunjian Tech.
