We know that there are many types of pneumatic actuators. Among them, AT, GT, and AW are the three common types of pneumatic actuators. These three pneumatic actuators have their own characteristics, according to different occasions and specific conditions. Choose different types of actuators, then, what is the specific difference between the three types of pneumatic actuators: AT, GT, and AW?
The pneumatic actuator of the AT series can be said to be a simple actuator. It is designed with a double piston rack and pinion rotation structure. It can also be divided into two types: double-acting and single-acting. The actuators are suitable for Outdoors in various non-corrosive environments.
GT series pneumatic actuator is a very commonly used one. It has many advantages. It can be said that GT series pneumatic actuator can account for 80% and more of the market. It is not only low in price, but also small in size, light in weight, easy to install, and flexible in action. As long as there is an air source, the valve can be switched on and off. The combination of these characteristics makes it a highly used pneumatic actuator.
The characteristic of the AW series pneumatic actuator is that the output torque is larger. Generally, it adopts a fork-type transmission mechanism. The output torque can change with the change of the angle. When the valve is opened and closed, its torque is very large. The law of the point on the valve is consistent. In addition, when the shift fork and the shift fork arm are overlapped in height, this greatly saves space and satisfies the needs of various large rotary valves. Not only these, it also has the advantages of safety and explosion-proof, which can be widely used in power plants, chemical plants and other production processes that require high safety.
