Stainless steel flange butterfly valve model and application

Stainless steel flanged butterfly valve can be divided into soft seal and hard seal according to the material of the sealing surface.
According to the "Valve Model Preparation Method", the common soft-sealed stainless steel flange butterfly valve models are: D41X-16P (handle operation), D341X-16P (worm gear drive), D641X-16P (pneumatic), D941X-16P (electric) . Common hard-sealed stainless steel flange butterfly valve models are: D343W-16P (worm gear), D643W-16P (pneumatic), D943W-16P (electric).
Soft sealing stainless steel flange butterfly valve: excellent sealing performance, can achieve two-way sealing and zero leakage. Soft seals are suitable for air, water, steam, various corrosive media, mud, oil, etc.

Hard-sealed stainless steel flange butterfly valve: resistant to high temperature and high pressure, it is widely used in various important pipelines including process control in major industrial fields such as oil and gas exploration, offshore platforms, petroleum refining, petrochemical, inorganic chemical, energy power generation and other major industrial fields.

Compared with other material butterfly valves, stainless steel flanged butterfly valves have many advantages in application fields. Because of the material characteristics, stainless steel butterfly valves have advantages in pressure resistance, heat resistance, cold resistance, physical and chemical openness, and butterfly valve service life. It is widely used in civilian food industry, chemical plants, crude oil, pharmaceuticals and other special industrial production chains.
