This is a chemical industry gate valve made of Alloy20. The body is made of Alloy20 (a corrosion-resistant alloy, also called Alloy 20), with a metallic finish, suitable for highly corrosive environments. It is a rising stem flange gate valve, with a handwheel-driven stem for raising and lowering. The gate is perpendicular to the flow direction of the medium, enabling pipeline opening and closing. The valve cover is bolted for easy maintenance. This chemical industry gate valve is a core opening and closing component for industrial pipelines.

Advantages
Superior Corrosion Resistance
Alloy20 material contains elements such as nickel, chromium, and molybdenum, making it far more resistant to highly corrosive chemical media such as sulfuric acid, phosphoric acid, and nitric acid than ordinary stainless steel (e.g., 304/316).
Suitable for Chemical Applications
Class 150 pressure rating + flange connection, conforming to general installation standards for chemical pipelines, offering strong compatibility.
Low Opening and Closing Resistance
The gate valve's straight-through flow path + gate structure results in low media flow resistance, suitable for opening and closing control in high-flow-rate pipelines.
Easy Maintenance
The rising stem design allows for intuitive assessment of valve status, and the bolted valve cover facilitates future replacement of seals or the gate.
Features
Exclusive Material
Alloy20 is a corrosion-resistant alloy specifically developed for the chemical industry, designed to address the issue of ordinary stainless steel's resistance to strong corrosion;
Rising Stem Design
The valve stem rises and falls with the opening and closing action, allowing direct confirmation of the valve opening by observing the stem position, avoiding the "blind operation" risk of non-rising stem gate valves;
Reliable Sealing
The metal hard seal structure is suitable for high and low temperature (-20℃~400℃) conditions in chemical media, ensuring a long seal life.
Application Scenarios
Main applications in highly corrosive chemical pipeline systems:
Chemical production
Pipelines for sulfuric acid/phosphoric acid preparation units;
Pharmaceutical industry
Pipelines for the production and transportation of corrosive pharmaceutical solutions;
Metallurgical industry
Acid circulation pipelines for pickling processes;
Environmental protection
Wastewater treatment pipelines containing strong acids/alkalis.
