D373H Wedge Metal-seat butterfly valve

Purpose
Butterfly valve for the petroleum,chemical,food,medicine,metallurgy,shipbuilding,
paper,industrial environment protection,water supply and drainage,on high-level pipeline architecture can be in a variety of corrosive,noon-corrosive gases,liquids,
fluids and solid powder loaded pipelines and containers for the headstock or adjust the medium flow purposes.
Features

1. Butterfly plate ring for soft and hard metal sheets stacked with metal hard sealing and sealing of the dual advantage of flexibility in terms of low temperature and high-temperature circumstance,have excellent sealing performance.
2. Using three-dimensional eccentric structure,butterfly valve base plate with almost no friction,with more clearance seal function is tightening.
3. Valve body sealing surface,the use of welding stainless steel,cobalt-based alloy,sealing surface wear-resistance,long service life.
4. Unique structure,operation flexibility,labor-saving,convenient and free from the pressure ring high-and low-impact,reliable sealing performance.
