YNTO stainless steel wafer-type hard-seal butterfly valve with a white stainless steel actuator
The electric wafer-type triple eccentric multi-layer metal hard-seal butterfly valve is widely used in industrial pipelines with medium temperatures below 425°C, such as in metallurgy, power, petroleum, chemical, water supply and drainage, and municipal construction, for regulating flow and cutting off fluids.
The electric wafer-type triple eccentric multi-layer metal hard-seal butterfly valve is widely used in industrial pipelines with medium temperatures below 425°C, such as in metallurgy, power, petroleum, chemical, water supply and drainage, and municipal construction, for regulating flow and cutting off fluids. This valve adopts a triple eccentric structure, with both the valve seat and butterfly plate sealing surfaces made of cast steel and stainless steel, offering excellent corrosion resistance. It is characterized by easy operation, good sealing performance, long service life, and convenient installation.
