    Description

    Single-seat fluorine lined control valve adopts full fluorine lined body and trim structure to effectively prevent the corrosion of metal materials in the valve by corrosive media. The metal body cavity is subjected to serrated machining treatment so as to make the lining materials fully fit into the metal and prolong the service life and performance of lining materials. The stem seal is the compound seal of F46 bellows seal and V PTFE packing, which can eliminate the possibility of media leaking from the stem to the outside. The unbalanced full lined control valve is especially suitable for very corrosive media under low pressure and normal temperature service conditions.
