Stainless Steel Metal Seated Gate Valve - China Suppliers & Factory for High Performance Flow Control

Stainless steel gate valves are expertly manufactured in China, providing exceptional control over media flow by utilizing a gate that moves perpendicularly to the flow direction. Ideal for full open or full close operations, these valves are not designed for throttling. Key features of our products from reliable suppliers include low fluid resistance, minimal pressure drop, and outstanding sealing performance. As a trusted factory, we ensure that our stainless steel gate valves meet the highest quality standards for various industrial applications

    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.

    Product Features

    1. Made from austenitic stainless steel, offering excellent corrosion resistance against oxidizing acids.

    2. Media flow remains undisturbed, ensuring low fluid resistance and minimal pressure drop.

    3. Gate movement is perpendicular to the media flow, requiring minimal torque for operation and reducing effort.

    4. Bidirectional flow capability allows media to flow in either direction without affecting performance, making it ideal for pipelines with potential flow direction changes.

    5. Compact design with shorter structural length due to the vertical gate position.

    6. Exceptional sealing performance, with minimal erosion on the sealing surface when fully open.

    Frequently Asked Questions

    What are the main applications of this metal-seated gate valve?
    It is ideal for weakly corrosive media pipelines like nitric acid and steam systems, and is widely used in petroleum, chemical, power plants, and fire protection systems.
    Why is the rising stem design recommended for fire protection systems?
    The rising stem design is highly recommended because it allows operators to easily and quickly verify the open or closed status of the valve visually.
    Can this valve handle changes in flow direction?
    Yes, it features a bidirectional flow capability that allows media to flow in either direction without affecting its performance, making it perfect for pipelines with potential flow direction changes.
    What is the maximum working temperature and pressure?
    The valve is designed to operate safely at temperatures up to 200℃ and can handle pressures ranging from 1.6MPa to 20.0MPa.
    What materials are used for the valve body and sealing surface?
    The valve body is made from high-quality stainless steel or cast steel. The sealing surface features stainless steel combined with hard alloy, or a full hard alloy overlay for exceptional durability.
    What is the benefit of the vertical gate position?
    The vertical gate position allows for a more compact overall design, resulting in a shorter structural length that saves valuable installation space in complex pipeline systems.
