China Stainless Steel Metal Seated Gate Valve Suppliers | High-Quality Factory Direct Flow Control Solutions

Stainless steel gate valves manufactured in China are engineered to efficiently control the flow of media by elevating or lowering a gate that moves perpendicular to the flow direction. These valves are ideal for reliable full open or full close operations, making them unsuitable for throttling applications. With low fluid resistance and minimal pressure drop, these gate valves ensure excellent sealing performance, catering to the needs of various industries. As a leading supplier and factory of stainless steel gate valves in China, we guarantee high-quality products tailored to meet your precise requirements

    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 (FAQ)

    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 whether the valve is currently in an open or closed status.
    Is this valve suitable for pipelines with flow direction changes?
    Yes, it features a bidirectional flow capability that allows media to flow in either direction without negatively affecting its performance.
    What is the maximum working temperature and pressure?
    The valve can safely operate at temperatures up to 200℃ and is designed to handle pressures ranging from 1.6MPa to 20.0MPa.
    What materials are used for the valve's construction?
    The body is made from high-quality stainless steel or cast steel, while the sealing surface utilizes stainless steel combined with a hard alloy or a hard alloy overlay.
    What is the benefit of the vertical gate position?
    The vertical gate position allows for a compact design with a shorter structural length, which significantly saves installation space in tight pipeline environments.
