Description Material Performance Product Size Specifications

一、Products [electric flange ventilation butterfly] details：

Product model：D941W

Product name：Electric flange ventilating butterfly valve

Product features: Electric flange type ventilation butterfly valve, pneumatic flange type ventilation butterfly valve, flange type ventilation butterfly valve use and characteristics. The butterfly valve adopts the same material as the valve body to be processed into a sealing ring. The suitable temperature and body material, nominal pressure is less than 0.6MPa, suitable for general ventilation for regulating media flow in industry, metallurgy, environmental protection and other pipeline. Its main features are: 1, design novel, reasonable, unique structure, light weight, open and close quickly. 2, operating torque is small, easy to operate, labor-saving dexterity. 3, the use of materials to meet the low, medium and high temperature of different media and corrosive media.

Part name	Material Science
valve body	Cast steel, stainless steel, nickel chromium molybdenum steel, chromium molybdenum titanium and other special materials
Disc	Cast steel, stainless steel, nickel chromium molybdenum steel, chromium molybdenum titanium and other special materials
Seal ring	Same as valve body
