Product description
A Single Gate Disc Gate Valve is a gate valve that uses a single gate to linearly lift and control the flow of media. It is used for switching control and flow direction isolation of liquids or gases in pipelines.
Applications
Upstream Oil and Gas Extraction
Used in oil wells and gathering pipelines, it is used for shutting down pipeline sections to stop the flow of crude oil or natural gas, protecting downstream equipment, preventing pipeline backflow, and quickly cutting off the medium in case of abnormal wellhead pressure.
Midstream and Downstream Pipeline Transportation
Used in long-distance pipelines and stations, it enables pipeline section closure for pipeline maintenance or expansion, switching between different pipeline flow directions, segmented pressure reduction, and preventing medium leakage in abnormal situations.
Chemical Production and Storage Units
Used in reactors, storage tanks, and transmission pipelines, it enables the isolation of liquid or gas flow, process unit switching, emergency shutdown, and prevention of medium mixing, thereby ensuring production sequence and safe operation.
Power Plant Steam and Fuel Systems
Used in steam, feedwater, and fuel networks, it enables pipeline closure to control the flow of steam or fuel, supports boiler or turbine maintenance operations, and quickly cuts off fluids in emergencies to ensure equipment and personnel safety.
Municipal Water Supply and Sewage Pipeline Network
Used for water supply, drainage, and sewage treatment pipelines, enabling pipe section closure to isolate faulty pipelines, switch water supply areas, control pipeline pressure and flow, and ensure smooth pipeline maintenance and emergency operations.
