The fully welded trunnion mounted ball valve with bypass is designed for long-distance pipeline systems where high reliability and low maintenance are essential. Its fully welded body construction eliminates potential external leakage paths, making it especially suitable for buried and underground installations.

Equipped with an integrated bypass line, the valve enables pressure equalization before operation, effectively reducing operating torque and extending seat service life. A dedicated drain valve allows safe cavity pressure release and pipeline drainage during maintenance, significantly improving operational safety.

This valve is supplied with a worm gear operator for smooth and controlled operation in high-pressure, large-diameter pipelines. It is widely used in gas transmission, water supply, district heating, and industrial pipeline networks.
