ZZFX/ZZFW series explosion-proof flame-retardant breathing valve is made of stainless steel, high quality aluminum alloy or cast iron, light weight and good corrosion resistance. The sealing surface between valve plate and valve seat is made of engineering plastics. When the valve is closed, the sealing performance is good, reaching ANSI B16.104 VI level standards. The fire-retardant layer is made of stainless steel and uses porous fire-retardant measures to provide excellent fire-resistance. The overall structure is designed according to the principle of self-energizing and is the best choice for explosion-proof structures.
