1)Uses

GT series valve pneumatic actuator, powered by compressed air, is the driving device for opening and closing rotary valves such as ball valves and butterfly valves. It’s the ideal device for remote centralized or separate control of industrial automatic pipelines.

The pneumatic actuator can be equipped with the solenoid valve, positioner (span indicator), reply device, filter, pressure reducer, various limit switches and manual devices.

2)Main technical parameters
