Description

A trunnion-mounted ball valve in cast steel, designed for long-distance pipelines and general industrial pipelines. The fixed-ball design provides bi-directional sealing with a spring-loaded seat structure, suitable for high-pressure and large-diameter applications across corrosive and non-corrosive media.
