Description
1. Overview of Stainless Steel Gate Valve
Stainless steel gate valves are designed to control the flow of media by raising or lowering a gate perpendicular to the flow direction. These valves are used for full open or full close operations and are not suitable for throttling. Key features include low fluid resistance, minimal pressure drop, and excellent sealing performance.
Applications:
- Ideal for weakly corrosive media pipelines, such as nitric acid and steam systems
- Widely used in petroleum, chemical, power plants, and other industries for oil, steam, and water pipeline control
- Suitable for fire protection systems with recommended use of rising stem design for easy visibility of valve status
2. Product Features
- Made from austenitic stainless steel, offering excellent corrosion resistance against oxidizing acids.
- Media flow remains undisturbed, ensuring low fluid resistance and minimal pressure drop.
- Gate movement is perpendicular to the media flow, requiring minimal torque for operation and reducing effort.
- Bidirectional flow capability allows media to flow in either direction without affecting performance, making it ideal for pipelines with potential flow direction changes.
- Compact design with shorter structural length due to the vertical gate position.
- Exceptional sealing performance, with minimal erosion on the sealing surface when fully open.
