Product Details

Underground Fully welded ball valves are especially designed for gas transportation and storage industries. Compared to bolted body, the ex-stem fully welded body design can prevent any potential leakage from connection of body and bonnet. And the forged body has the advantages of consistent grain size and even thickness to ensure reliable and safe sealing performance. Equipped with extension stem, it can work underground. The transition pipe can be welded to the ends of valve during production.
