■ GIQPneumatic High Vacuum Butterfly Valve ■ GIQ pneumatic high vacuum butterfly valve uses solenoid directional valve to change the direction of air passage, and co*ols 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 *itioner. ■ 主要技术性能Main Technical Performance ■■■ 适用范围:Applicability 105~1.3×10-4Pa 阀门漏率:Valve Leak Rate ≤1.3×10-4Pa.L/S. 适用温度:Applicable Temperature -25~+80℃(*橡胶) -30~+150℃(氟橡胶) 气源压力:Mains Voltage 0.4~0.6MPa 安装方向:Mounting Direction 任意 ■ 主要零件材料Materials of Main Parts ■■ 阀体、阀盖、阀杆:碳钢或不锈钢密封件:*橡胶、氟橡胶。
