The 10PF Series linear motion single-seatlined control valve adopts full fluorine lined body and trim structure toeffectively prevent the structure to effectively prevent the corrosion of metalmaterials in the valve by corrosive media. The metal body cavity is subjectedto serrated machining treatment so as to make the lining materials fully fitinto the metal and prolong the service life and performance of liningmaterials. The stem seal is the compound seal of stem seal is the compound sealof F46 bellows seal and V PTFE packing, which can eliminate the possibility ofmedia leaking from the stem to the outside. The unbalanced full lined controlvalve is especially suitable for very corrosive media under low pressure andnormal temperature service conditions.
