The product is suitable for the transportation of liquids and gases (including steam) in various industrial pipelines. After selection, it can also be used in special media such as chlorine, oxygen, high vacuum, sulfur resistant or corrosive media. The product can also have a fireproof structure for selection. Adopting a double eccentric butterfly plate with a spherical sealing surface, paired with a single piece flexible lip seal seat, suitable for occasions requiring reliable sealing and good adjustment characteristics. Due to the design of the double eccentric butterfly plate, the valve has tight sealing performance and long service life. It can be used for quickly cutting off or adjusting flow. The seat of the dual eccentric high-performance butterfly valve is sealed with PTFE material, and the valve can achieve ANSI Class VI zero leakage. Suitable for gas transportation and process media with high requirements for valve life, with a normal service life of up to times. The outside of the valve seat is a movable insert that is fixed by a spring. The tighter the flange clamp and the greater the pressure, the better the sealing performance of this high-performance butterfly valve. The dual eccentric high-performance butterfly valve adopts a dual eccentric butterfly plate with a spherical sealing surface, paired with a single piece flexible lip seal seat, suitable for occasions requiring reliable sealing and good adjustment characteristics. Due to the design of the double eccentric butterfly plate, this high-performance butterfly valve has tight sealing performance and an ultra long service life. It can be used for quickly cutting off or adjusting flow.
