Overview：
The all-metal hard-sealed wafer butterfly valve is a type of butterfly valve that uses metal as the sealing pair (both the valve seat and the butterfly plate sealing surface are made of metal), and achieves pipeline on-off or flow regulation through wafer connection (the valve body has no flange and is clamped and fixed to the two end faces of the valve by bolts passing through the pipeline flange).
All-metal hard-sealed wafer butterfly valves, as key control components in industrial pipeline systems, are widely used in harsh working conditions in industries such as petroleum, chemical engineering, power, and metallurgy, thanks to their core advantages of high-temperature resistance, high-pressure resistance, and stable sealing performance.
Nominal diameter: 10mm to 2000mm and 1/2" to 80".
Working pressure: 0.25MPa to 76.0MPa/150Lb to 4500Lb/10K to 320K.
Adopted standards: GB, DIN, API, ANSI, JIS, BS, etc.
