resin coated sand casting stem gate valve

Product Description

Ductile iron valve cover adopts advanced casting process, make the body precise size, smooth surface, due to the complexity of lumen, metal adhering sand and sand inclusion and other defects, the process of adopting laminating resin sand cores, thoroughly eliminate the inner cavity of the adhering sand, lumen is bright and clean without any adhering sand, to prevent leakage, casting by impregnation processing craft, make internal organization more dense, seepage pressure test after the 100% per piece, total pressure, leakage through the coating and machining, make each size meet the requirements, the product is well received by users, are exported to the United States, used in civilian and industrial gas conduit burning gas, perennial large supply many varieties.
