API600 Standard WCB CF8 CF8M Rising Stem Bevel Gear Operated Wedged Gate Valve
Product Introduction:
Gate valve is a valve product in which the closing element (gate) moves vertically along the centerline of the passage. Gate valves are mainly used for cutting off in pipelines. Gate valve is a widely used type of valve. Gate valves can only be used for fully open and fully closed blocking in pipelines, and cannot be used for adjustment or throttling.
Compliance with API600 standard, our cast steel stainless steel gate valve products are widely used as opening and closing devices for connecting or cutting off media in oil and steam pipelines in petrochemical, thermal power plants, and other oil and steam pipelines.
