Ventilation butterfly valve

The low load ventilation butterfly valve adopts the design of metal face seal with middle line structure. Metal seal seat around the valve plate, this structure can achieve the leakage of the valve seat. This series of butterfly valves have the advantages of simple structure, light weight, mature manufacturing technology and convenient maintenance. They are suitable for flow and pressure control under low pressure conditions, and can also be used in high temperature fluids. They are widely used in steel, building materials, petrochemical, power plant and other industrial sectors.
