370D series butterfly valves

370D series product features
★ The valve body and valve seat adopt double groove connection, which ensures the convenient and accurate connection between the valve body, valve seat and butterfly plate, reduces the installation difficulty, and completely solves the problem of the valve seat being rubbed and deformed due to improper installation and debugging .
★ The double groove positioning strength is high, the interference between the butterfly plate and the valve seat is more accurate and stable, the opening torque is light and the consistency is good, thereby further improving the sealing performance of the valve.
★ The double groove positioning structure basically eliminates the phenomenon of valve seat creep during valve opening and closing, and improves the service life and reliability of the valve.
★ Adopt large arc wide side design, suitable for a variety of flange connections.
