The actuator is one of the indispensable configurations in the industrial automation process. The use of the actuator is very frequent, and it is generally installed in harsh environments such as high temperature and high pressure, and is prone to failure. According to different air sources, actuators are divided into electric, pneumatic, hydraulic, etc. Here, the editor mainly introduces the comm…

Pneumatic actuator single-acting: When the compressed air enters the middle cavity between the two pistons of the cylinder from the air port D, the two pistons are separated and moved toward the two ends of the cylinder, forcing the springs at both ends to compress, and the air in the air cavities at both ends is discharged through the air port, while making The two-piston gear timing belt output …

The fork-type pneumatic actuator is a kind of pneumatic actuator, and its reputation in the market is still very good, and it is deeply loved by users. So what is the difference between the fork type pneumatic actuator and other actuators?…

Generally speaking, the piston type has a long stroke and is suitable for occasions requiring a large thrust; while the film type has a small stroke and can only drive the valve stem directly; the fork type pneumatic actuator has the advantages of large torque, small space, and a more consistent torque curve. The torque curve and other characteristics of the valve are not very beautiful, and are o…

Pneumatic valve is an actuator that uses compressed air to drive and operate the valve. Its opening and closing speed is relatively fast. It is often used for quick two-position cut-off, and can also be used to adjust flow. Because it mainly relies on air source to perform operation, In flammable and explosive situations, it has high practicability and can be used to control gas, liquid, oil, and …

Swing check valves can be installed horizontally or vertically. The disc of swing check valve rotates around the rotating shaft, and its fluid resistance is generally smaller than that of lift check valve. It is suitable for occasions with larger diameters, and the installation position is not limited. It is usually installed in horizontal pipelines. It is suitable for use with for larger diameter…

The electric three-way ball valve is composed of an electronic electric actuator and a three-way ball valve. It is a rotary cut-off regulating valve with the advantages of tight closing, compact structure, light weight and convenient maintenance. It is widely used in pipeline automation control of corrosive media such as gas, liquid, steam and oil.…

The angle control valve has a simple flow path and low resistance, and is generally suitable for forward use (installation). However, in the case of high pressure drop, it is recommended to use the angle control valve in reverse, to improve the unbalanced force and reduce the damage to the valve core, and it is also conducive to the flow of the medium and avoids coking and clogging of the control …
