一、概述Outline  

QJ（D/S）RF型精小型氣動襯氟O型切斷球閥是由氣動活塞式執行機構和襯氟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。
該產品以壓縮空氣為動力源，借助閥門定位器（或電磁閥）對閥門實現連續調節（或位式控制）。
該產品閥體內壁和金屬閥內組件襯由耐腐蝕、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、流阻小、流通能力大等優點，特別適用各行業對酸、堿等強腐蝕性介質場合。

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.
