一、概述Outline
QJ(D/S)RZ型氣動高真空O型球閥是以通過電磁換向閥改變氣路方向，控制執行氣缸來驅動球閥，達到接通或切斷真空(壓力)系統管路中的介質流目的。應用于真空、乳制品、酒業、生物工程、食品、制藥、飲料、化妝品及化工領域。可選配反饋信號裝置及電氣閥門定位器。
QJ (D / S) RZ-type high-vacuum O-pneumatic valve solenoid valve is changed by the direction of gas to control the implementation of the cylinder to drive the ball, to connect or disconnect the vacuum (pressure) pipeline system in the media flow purposes. Used in a vacuum, dairy products, wine, biotechnology, food, pharmaceutical, beverage, cosmetics and chemical industries. Optional feedback device and electrical valve positioner.
