Directly buried fully welded fixed ball valve with expansion rod Q367HF

Compared to ordinary valves, which require flanges, screws, and gaskets for connection to pipelines, fully welded ball valves with direct burial type do not consume a large amount of material resources during valve-to-pipeline connection, which is beneficial to the global environment and energy conservation and emission reduction. These fully welded ball valves with direct burial type are connected to pipelines via welding, eliminating the need for flanges, screws, and gaskets. They exhibit good sealing performance and are easy to operate.
