一、V-GIQ-B型系列气动高真空蝶阀概述

V-GIQ-B型系列气动高真空蝶阀的气动执行器是以压缩空气为动力，通过电磁换向阀改变气路方向，推动活塞齿条、齿轮的机械运动，以角行程输出扭矩来驱动蝶阀，作启闭运动。从而达到接通或切断真空管路中气流的目的，是目前一种新型的气动执行器控制的气动蝶阀，分为双作用和单作用(弹簧复位)气缸。可选配反馈信号装置及电气阀门定位器。

适用的工作介质为空气和非腐蚀性气体。

The pneumatic actuator of the V-GIQ-B series pneumatic high vacuum butterfly valve is powered by compressed air and changes the direction of the air path through an electromagnetic directional valve, driving the mechanical movement of the piston rack and gear, and outputting torque through angular stroke to drive the butterfly valve for opening and closing motion. In order to achieve the purpose of connecting or cutting off the airflow in the vacuum pipeline, it is currently a new type of pneumatic butterfly valve controlled by pneumatic actuators, which is divided into double acting and single acting (spring return) cylinders. Optional feedback signal device and electrical valve locator.

The applicable working media are air and non corrosive gases.
