A solid wedge gate valve is a gate valve that uses a solid wedge-shaped gate to linearly lift and control the flow of media. It is used for switching operations and flow direction isolation of liquids or gases in pipelines.
Valve Body and Gate Materials
Carbon steel WCB, alloy steel F51, 304/316 stainless steel, Inconel; solid wedge gates available with hard chrome plating, Stellite coating, or wear-resistant alloy.
Dimensions and Connections
Nominal diameter DN15–DN1200 (1/2"–48"), pressure rating Class 150–2500; face dimensions can be customized according to ASME B16.10 or project requirements; flange ends RF/FF/RTJ; weld end bevel dimensions customized.
Gate and Body Structure
Single or double wedge solid gate; cuboid or round valve body; full bore or reduced bore; cryogenic extended stem and bonnet lengthening available upon request.
Actuation Methods
Manual lever, worm gearbox; electric, pneumatic, hydraulic, or pneumatic-hydraulic actuators; torque output, switching speed, and failure mode customized.
Sealing and Functional Modules
V Multi-spring packing, zero-leakage valve stem seal, fireproof structure, anti-blowout valve stem design, corrosion-resistant or heat-insulating jacket, and emergency grease injection port available.
Upstream Oil and Gas Extraction
Used in crude oil or natural gas transmission pipelines to close sections and stop fluid transport, supporting well maintenance, segmented operation of gathering and transmission pipelines, and prevention of backflow or overpressure.
Downstream Oil and Gas Pipelines
Used in long-distance pipeline trunk lines and branches to close pipelines to switch transmission lines, bypass pump stations, or perform pipeline maintenance, while controlling pressure fluctuations.
Chemical Production and Storage
Used in reactors, storage tanks, and multi-path transmission pipelines to enable full-open or full-close operation of the medium, directing fluids to designated process units or isolating pipelines, and preventing cross-mixing of media.
Power Plant Steam and Fuel Systems
Used in steam, fuel oil, and cooling water networks to cut off pipelines to control fluid direction, supporting boiler start-up and shutdown, bypass circulation, and system maintenance operations.
Water Treatment and Municipal Pipelines
Used in water supply, drainage, and sewage treatment pipelines to close sections to isolate fault areas, switch water supply lines, or perform network maintenance and flow regulation.
