GIQ型高真空气动蝶阀 GIQ Pneumatic High Vacuum Butterfly Valve
GIQ型气动高真空蝶阀是通过电磁换向阀改变气路方向，控制执行气缸驱动蝶阀作启闭运动。高真空气动蝶阀用于接通或切断真空管路中的气流。永嘉县科本真空阀门厂生产的高真空气动蝶阀适用介质为纯净空气和非腐蚀性气体。气动高真空蝶阀可选配反馈信号装置及电气阀门定位器。
GIQ pneumatic high vacuum butterfly valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the butterfly valve opened and closed. It is used to put through or cut off the airflow in vacuum pileline. Applicable medium can be pure air and noncorrosive gases. They may be fitted with signal feedback device and electropneumatic valve positioner.
