  • Introduction
  • Specifications
Dt73 wafer butterfly valve of resilient hard sealing using ”U” type stainless ring, this sealing ring contact with three-dimensional eccentric disc. Achieve sealing surface separated when butterfly board open, sealed when close; extend using life、good sealing. Widely used metallurgy 、power、petroleum、chemical、air、gas、combustible gas and other corrosive pipes that media temperature≤550℃, for adjusting flow and cutting off fluid
1、  simple structure、impact、light weight、 easy to install and uninstall、maintain
2、  using “U” type sealing ring, with some resilience even under high pressure、low pressure environment, it and butterfly board all be with good sealing
3、  three-dimensional eccentricity distance, through rigorous calculation, “U” type sealing ring and butterfly board with no friction, long using life
4、  sealing surface of butterfly board using Co-based cemented carbide, wear resistance of sealing surface, long using life
5、  special structure,” on-off” just need to rotate 90°of valve stem. Flexible operation、convenient、effort、not affected by media pressure, reliable sealing
6、  high pressure resistance、low pressure resistance、corrosion resistance
