Product Detail

The Didtek Gear Operated LF2 Top Entry Ball Valve is a premium fluid control solution designed for high-pressure networks and extreme low-temperature environments. Forged from ASTM A350 LF2 carbon steel, its standout advantage lies in the Top Entry construction—allowing for rapid in-line maintenance or replacement of the ball, seats, and seals by simply removing the bonnet, without extracting the valve from the pipeline. Equipped with a high-performance Gear Operator, it ensures precise and effortless manual control even in large-diameter and high-differential pressure applications.
