The difference between pneumatic valve actuators AT and GT

Pneumatic valve actuator is a device that converts pneumatic signals into mechanical torque, used to drive valve opening and closing. Pneumatic actuators are important execution components in industrial automation control systems, widely used in industries such as chemical, petroleum, metallurgy, and power.
In the series of pneumatic valve actuators, AT and GT are two common models, which have certain differences in structure, performance, and application scope:
1. Structurally, the AT pneumatic actuator adopts a dual piston rack and gear rotation structure, which is divided into two types: double acting and single acting (spring reset). The GT pneumatic actuator adopts a worm gear transmission structure.
2. In terms of performance, AT pneumatic actuators have the characteristics of simple structure, low manufacturing cost, small size, light weight, and easy maintenance. GT pneumatic actuators have high output torque, high transmission efficiency, smooth operation, and low noise.
3. In the application field, AT pneumatic actuators are suitable for various non corrosive or corrosive environments outdoors or indoors. GT pneumatic actuators are suitable for various industrial applications, such as chemical, petroleum, metallurgical, power, etc.
