a) GI type manual or worm gear operated valve has multiple open and close locking function, angle degree of the plate is 0º-90º.

b) GIQ type pneumatic vacuum butterfly valve operated by compressed air and through electromagnetic device to change the airflow control the actuator rotated then drive the valve open or closed. Actuator can be double acting and single-acting spring return type, also can drivenintelligentpositioner through the external input signal to control the pneumatic driving.

c) GID series electric butterfly valve operated by electrical device to drive the valve plate to open or closed. Electric actuator is passive contact type as factory setting, can beoptionalon-off and regulating control type to achieve adjusting control.
