气动衬氟V型调节阀它由轻小型气动执行机构衬氟塑阀两部分组成。由于阀门接触介质的部位均采用高压注塑工艺衬有能耐腐蚀，耐老化的聚全氟乙丙烯（简称F46)或PFA，填料函密封采用聚四氟乙烯波纹管密封。因而该调节阀能广泛用于化工、石油、冶金、医药、电力等行业中对酸、碱等强腐蚀介质和有毒、易挥发等气体、液体介质的过程控制。
Pneumatic rubber fluorine V regulator it by light small pneumatic actuators lining fluorine plastic valves in two parts. Because the valve parts adopt high pressure injection molding process line of contact medium capable of corrosion, aging resistance of fep (F46) or PFA, gland seal using ptfe bellows seal. So the valve can be widely used in chemical, petroleum, metallurgy, medicine, electricity and other industries in the strong corrosive medium such as acid, alkali and toxic and volatile gas, liquid medium of process control.
