If you don’t find the answer you’re looking for, get in touch with us here.

  • What is a Bellow Seal Gate Valve?

    It is a type of Gate Valve designed with a metallic bellows to provide a hermetic seal, preventing any leakage from the valve stem. This design is particularly useful in applications where preventing leakage of hazardous or toxic substances is critical.

  • How does it work?

    The bellow in the seal gate valve expands and contracts with the movement of the valve stem, creating a tight seal that prevents fluid from leaking. This expansion and contraction allow the valve to open and close while maintaining a hermetic seal.

  • What are the main applications?

    They are commonly used in industries where leakage of fluids, especially hazardous or toxic ones, cannot be tolerated. This includes chemical processing, nuclear power plants, pharmaceuticals, and petrochemical industries.

  • What are the benefits of using one?

    Leak-free performance: The bellows design ensures a hermetic seal, preventing leaks. Long service life: Reduced stem wear and corrosion lead to a longer operational life. Maintenance reduction: With minimal leakage and wear, the need for frequent maintenance is decreased. Safety: Ideal for handling toxic, hazardous, or high-purity fluids, ensuring safety and environmental compliance.

  • What materials are used in their construction?

    They are typically made from materials compatible with the fluids they will handle. Common materials include stainless steel, alloy steels, and high-grade carbon steel. The bellows themselves are often made from stainless steel or other corrosion-resistant alloys.

  • How do I choose the right one for my application?

    When selecting a Bellow seal Gate Valve, consider factors such as: Fluid type and properties: Ensure material compatibility. Pressure and temperature ratings: Choose a valve that can withstand the operational conditions. Size and flow requirements: Select a valve that matches your system’s size and flow needs. End connections: Ensure the valve connections are compatible with your piping system.

  • Can they be repaired?

    Yes, these valves can often be repaired. However, due to their specialized design, it is usually recommended to have them serviced by professionals with experience in handling and repairing such valves to ensure integrity and performance are maintained.

  • What maintenance is required?

    It require minimal maintenance compared to conventional gate valves. Regular inspection for signs of wear or damage, especially to the bellows, is essential. Lubrication of the stem and checking the operation for smooth performance are also recommended.

  • Are they available in different designs?

    Yes, they come in various designs to suit different applications. This includes different types of bellows (such as multi-ply or single-ply), various end connections (flanged, welded, threaded), and different actuation methods (manual, pneumatic, electric).

  • Why is Freture the best place to buy from?

    Bellows Seal Gate valves are manufactured according to various international standards to ensure quality and safety. Common standards include ASME B16.34, API 600, DIN, and BS standards, which specify requirements for design, materials, testing, and performance.
