The pipeline butterfly valve apply to many liquid and gas pipelines, and are up to the standard of AWWA, widely used in power station, civic engineering water supply system. The valves possess properties as follows:
1.Possessing properties of good cutting off and adjusting, it can reach the sealing of air bubble level.
2.Fixable seat of machine can fully adjusts, can adjust and exchange seat in site, needn?t especial tools, haven?t to disassemble valve.
3.Open-close moment is minor, service life is long.
4.Valve can install in horizontal or vertical place.
