An API 608 Trunnion Mounted Ball Valve is a valve manufactured in accordance with the API 608 standard, which delineates specifications for ball valves, specifically those used in the petroleum and petrochemical industry. This valve configuration entails a fixed ball supported by trunnions or lower stems within the valve body. Such a design enhances stability and control, rendering it optimal for high-pressure and high-flow scenarios typical in industries like oil and gas, petrochemicals, and power generation.
