American Standard Butterfly Valve

The main structural features of the 815 and 830 series American standard butterfly valves are the wafer-type and flanged triple eccentric structure, while the main structural features of the 815 and 830L series butterfly valves are a valve body with a peripheral protrusion designed as a single flange structure with screw holes. The 815 and 830 series butterfly valves are widely used in pipelines for petroleum, chemical, industrial environmental water treatment, high-rise buildings, water supply and drainage, etc. Their characteristics are:

Due to the adoption of the triple eccentric structure, the sealing performance is reliable, ensuring that the disc does not contact the sealing seat during opening, eliminating uneven load on the sealing seat, extending the service life, ensuring reliable sealing performance, and offering advantages such as high temperature resistance, wear resistance, and corrosion resistance.
