一、概述Outline  

QJ（D/S）RF型精小型氣動(dòng)襯氟O型切斷球閥是由氣動(dòng)活塞式執(zhí)行機(jī)構(gòu)和襯氟O型球閥組成。閥芯采用襯氟圓柱形通孔球體和軟密封閥座。
該產(chǎn)品以壓縮空氣為動(dòng)力源，借助閥門定位器（或電磁閥）對(duì)閥門實(shí)現(xiàn)連續(xù)調(diào)節(jié)（或位式控制）。
該產(chǎn)品閥體內(nèi)壁和金屬閥內(nèi)組件襯由耐腐蝕、抗老化的聚全氟乙丙烯（F46），因而具有耐腐蝕性能良好、抗老化性能高、壽命長(zhǎng)、流阻小、流通能力大等優(yōu)點(diǎn)，特別適用各行業(yè)對(duì)酸、堿等強(qiáng)腐蝕性介質(zhì)場(chǎng)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.
