    Frequently Asked Questions

    What is a Double Block and Bleed Valve?

    A Double Block and Bleed (DBB) valve is a compact valve system that provides dual isolation and a bleed function in a single unit. It enhances safety, saves space, and reduces leakage points compared to traditional multi-valve setups used in the oil and gas industry.

    Where are Vimec valves manufactured?

    Vimec Valves are entirely designed, engineered, and manufactured at our state-of-the-art facility in Italy, ensuring precision, high-quality material sourcing, and strict adherence to European and international production standards.

    What industries use sampling valves?

    Sampling valves are critical for safely extracting process media without halting operations. They are heavily utilized across petrochemical, oil and gas, pharmaceutical, chemical processing, and power generation industries ensuring operator safety and zero-emission.

    What standards do Vimec valves comply with?

    Vimec valves are rigorously tested and fully compliant with major international certifications, including ISO, PED, ATEX, and API norms. We guarantee absolute zero-emission reliability and safety under severe and corrosive operating conditions.
