SEFB Electric fluorine-butterfly valves
Information
SEFB Electric fluorine-butterfly valves,component by 3601R series angle travel electronic electric actuators and valve body.
Cavity of valve body and plate are lined with plastic injection molding adopt high corrosion resistance, ageing fluorinated YiBing ene, corrosion resistance and reliable sealing.
This series of pneumatic fluorine-butterfly butterfly valve is mainly used in chemical medicine, food processing industries papermaking water for such strong corrosive medium ph of regulation or cut off.
