Product Detail

The Didtek LF2 Full Bore Trunnion Ball Valve is a high-performance fluid control solution specifically engineered for high-pressure industrial and low-temperature services. Forged from ASTM A350 LF2 carbon steel, it ensures exceptional impact toughness at temperatures as low as -46℃. The Full Bore design provides an unobstructed flow path, minimizing pressure drop and facilitating pigging operations in transmission pipelines. Featuring a Trunnion-mounted structure, the valve maintains low operating torque even under extreme high-pressure differentials.
