一、概述Outline  

QJ（D/S）RF型精小型气动衬氟O型切断球阀是由气动活塞式执行机构和衬氟O型球阀组成。阀芯采用衬氟圆柱形通孔球体和软密封阀座。
该产品以压缩空气为动力源，借助阀门定位器（或电磁阀）对阀门实现连续调节（或位式控制）。
该产品阀体内壁和金属阀内组件衬由耐腐蚀、抗老化的聚全氟乙丙烯（F46），因而具有耐腐蚀性能良好、抗老化性能高、寿命长、流阻小、流通能力大等优点，特别适用各行业对酸、碱等强腐蚀性介质场合。

QJ （D / S） RF-type fine cutting of small pneumatic fluorine O type ball valve is a pneumatic piston actuator and fluorine O type ball valve components. Spool using fluorine cylindrical hole sphere and soft seal seat.
The product is compressed air as power source, with the positioner （or solenoid valve） to achieve a continuous adjustment of the valve （or bit control）.
The product body wall and the metal valve components from the corrosion-resistant lining, anti-aging poly FEP （F46）, which has good corrosion resistance, aging resistance, long life, small flow resistance, flow capacity advantages, especially for the industry to acid, alkali and other strong corrosive media applications.
