    Frequently Asked Questions
    Q What is Double Block and Bleed (DBB) and why is it important?

    Double Block and Bleed (DBB) refers to a valve configuration that provides two seating surfaces that seal in the same direction, with a bleed port between them. This design ensures that any leakage past the upstream seat is safely vented, making it critical for high-risk process lines where leak prevention is essential.

    Q Is this valve compliant with fire-safe design standards?

    Yes. The valve is designed in accordance with API 607 and ISO 10497 fire-safe standards. This ensures that even in the event of a fire, the valve maintains its integrity and prevents hazardous leakage, making it suitable for use in oil & gas and petrochemical environments.

    Q What actuation options are available for this valve?

    The valve supports multiple actuation methods including manual handwheel, worm gear, electric actuator, and pneumatic actuator. It also features ISO 5211 direct mounting pads, making it straightforward to integrate with automated control systems and reduce installation complexity.

    Q What materials are available for customization?

    The valve is available in a wide range of materials to suit different industrial environments, including A694F52, A694F60, A694F65, A182F6A, A182F316, A182F347, and Inconel 625. These options allow customers to select the most appropriate material based on their specific process conditions and corrosion requirements.

    Q What is the difference between Full Bore and Reduced Bore configurations?

    A Full Bore valve has an internal diameter equal to the pipeline, allowing unrestricted flow and minimal pressure drop — ideal for applications requiring pigging or maximum flow capacity. A Reduced Bore valve has a smaller internal diameter, which results in a slight pressure drop but is more compact and cost-effective for general flow control applications.

    Q Which industries is this valve suitable for?

    This valve is engineered for a broad range of demanding industries including Oil & Gas, Chemical & Petrochemical, Power Generation, Water Treatment, and general high-pressure industrial applications. Its robust construction and compliance with international standards make it a reliable choice for critical pipeline systems across these sectors.
