Products Description

Gate valves are widely used in the petroleum,chemical, pharmaceutical, fertilizer, electric power and other industries as open-closetype control valves for connecting or cutting off media. The valve body can beselected from the body which forged or casting; the gate plate is designed as awedge-shaped elastic ram that is easy to seal with wear compensation, and thesealing surface is welded with corrosion-resistant and hard-wearing hard alloy;the valve seat is designed as detachable and valve body surfacing welding ,sealing surface welding and sealing surface matching the corrosion-resistantand wear-resistant hard alloy; valve stems are specially treated to ensuretheir strength, steel, corrosion and wear resistance. The gate valve isreliable in sealing, safe to use and easy to operate. Different materials canbe used to meet the needs of various working conditions. It is suitable for awide range of media, temperature and pressure. It is widely used in water,steam, oil, nitric acid, acetic acid and strong oxidizing media.
