It is special for controlling the noncorrosive or the strong corrosive media. Its body inner surface is unlined or lined with different fluorine plastics which can be selected to suit with different working temperatures and fluid pipelines.
Suitable temperature: 85, 100, 120, 150 according to the materials of lining and diaphragm
Three-way diaphragm valves are used to switch over, mix and divide the flow of corrosive or noncorrosive liquid, gas or powdery mediums. Upon opening and closing, the smooth flow channel effects less pressure loss, making operation quite labor-saving and maintenance fairly easy.
