Currently aPneumatic actuatorIt is the most critical tool in pneumatic valves, and as a pneumatic actuator, in fact, its role in the valve is to make the valve device more convenient when in use. Because the pneumatic actuator access makes the valve in the pipeline operation can drive the rapid linkage of the valve body parts, has a certain automation effect, and because the actuator itself is driven by energy, so for the valve body opening and closing parts of the drive also has a certain value. This valve due to the small fluid resistance is used to the fluid pipeline to play the role of opening and closing.

Performance of Pneumatic Actuators as Important Components in Pneumatic Valves

Currently aPneumatic actuatorIt is the most critical tool in pneumatic valves, and as a pneumatic actuator, in fact, its role in the valve is to make the valve device more convenient when in use. Because the pneumatic actuator access makes the valve in the pipeline operation can drive the rapid linkage of the valve body parts, has a certain automation effect, and because the actuator itself is driven by energy, so for the valve body opening and closing parts of the drive also has a certain value. This valve due to the small fluid resistance is used to the fluid pipeline to play the role of opening and closing.
As one of the opening and closing device, the pneumatic actuator installed on this valve uses compressed gas to push the piston to play a role in the valve stem connected to it, and drive the ball valve to move, thus playing a role in adjusting the fluid medium in the pipeline.
As one of the opening and closing parts, this ball around the axis of the ball valve for rotation, for the transport of the medium has a certain effect. Ball valve is characterized by wear resistance, good sealing performance, and because of the smaller resistance, so the internal valve body by less wear, service life is relatively long, this feature makes the use of this pneumatic valve in the pipeline comparison "handy".
The switch action of the actuator of the pneumatic actuator is driven by the air source, which is called DOUBLE ACTING, which is double acting. The SPRINGRETURN, that is, single-acting, only on or off is driven by the gas source, and the opposite action is returned by the spring.
In addition to the above differences, there is that after the air enters, the operation of the actuator opening and closing is also different. The double-acting is that air enters the actuator, the actuator starts to work, and the valve opens. When the valve needs to be closed, air needs to enter from another port. Single-acting is simpler, air enters, opens the valve, and automatically closes without air.
