Directly buried umbrella-type worm gear fully welded ball valve Q367HF/Q361HF

Compared to ordinary valves, the direct-buried umbrella-type worm gear fully welded fixed ball valve eliminates the need for flanges, screws, and gaskets for connecting to pipelines. The connection of valves to pipelines wastes a significant amount of material resources, which is not conducive to the global environment, energy conservation, and emission reduction. However, the direct-buried fully welded ball valve connects to pipelines without flanges, screws, or gaskets, through welding. It has good sealing performance and is easy to operate.
