Outline

The  low load butterfly Valve adopts the metal face seal Design of central line structure. The metal seat surrounds the disc. This structure can reduce the seat leakage. Featured by simple structure, light weight, mature manufacturing technology and convenient maintenance, the70SSeriesbutterfly valve is used for flow and pressure control in low pressure service conditions and is suitable for fluids of very high temperature. It is widely used in steel, building materials,

petrochemical industry, power station and other industries.
