Wuxi Xinming automatic control valve industry Co., Ltd. introduces the difference between pneumatic actuator, electric actuator and hydraulic actuator Pneumatic actuator, electric actuator, hydraulic actuator difference In the field of valve automation, the opening and closing of the valve will be used to the valve actuator, because it is more labor-saving and convenient, but also more quickly, and can complete the active control and remote control. But there are several varieties of valve actuator, each has its own advantages and disadvantages, so how to select the right valve actuator in the right place? At present, it is mainly divided into pneumatic actuators, electric actuators, hydraulic actuators, electro-hydraulic actuators, etc. The following describes the differences between these actuators. 1. pneumatic actuator The strengths of pneumatic actuators are: 1, the structure is relatively simple 2. The switching speed can be greatly improved 3, the gas compression is large, when closed, elastic 4, the acquisition of gas source is relatively easy. 5. After installing the governor, the switching speed can be adjusted according to their own needs Disadvantages are: 1. Because of the compressibility of gas, the speed is not easy to stick. 2, the structure is relatively large, so it is not suitable for large diameter high pressure valve 2. electric actuator The strengths of the electric actuator are: 1. Convenient installation 2. Protection and maintenance convenience 3, the volume can be completed ultra-miniaturization 4. Wide range of output torque 5, machinery can actively determine 6, strong applicability, not affected by ambient temperature 7, convenient control, can freely choose a variety of signals, suitable for amplification, recall, logic discrimination and calculation operations 3. hydraulic actuator The strengths of the hydraulic actuator are: 1. Simple structure, small volume 2, can output strength is large 3, due to hydraulic viscosity, can improve efficiency 4. Self-lubricating function and anti-rust function 5, can be long-distance active control 6. It can switch high speed and low speed to complete the speed change Disadvantages are: 1, piping, repair is not very convenient 2. Hydraulic components and pipelines are easy to leak 3. The change of viscosity caused by the change of oil temperature 4, not suitable for various operations on the signal According to the above, we can know that all kinds of valve actuators have their own advantages and disadvantages, but according to their own needs, they can still select suitable actuators. Through careful comparison, they will be able to find suitable valve actuators.

Pneumatic actuator, electric actuator, hydraulic actuator difference
In the field of valve automation, the opening and closing of the valve will be used to the valve actuator, because it is more labor-saving and convenient, but also more quickly, and can complete the active control and remote control. But there are several varieties of valve actuator, each has its own advantages and disadvantages, so how to select the right valve actuator in the right place?



At present, it is mainly divided into pneumatic actuators, electric actuators, hydraulic actuators, electro-hydraulic actuators, etc. The following describes the differences between these actuators.
1. pneumatic actuator
The strengths of pneumatic actuators are:
1, the structure is relatively simple
2. The switching speed can be greatly improved
3, the gas compression is large, when closed, elastic
4, the acquisition of gas source is relatively easy.
5. After installing the governor, the switching speed can be adjusted according to their own needs
Disadvantages are:
1. Because of the compressibility of gas, the speed is not easy to stick.
2, the structure is relatively large, so it is not suitable for large diameter high pressure valve
2. electric actuator
The strengths of the electric actuator are:
1. Convenient installation
2. Protection and maintenance convenience
3, the volume can be completed ultra-miniaturization
4. Wide range of output torque
5, machinery can actively determine
6, strong applicability, not affected by ambient temperature
7, convenient control, can freely choose a variety of signals, suitable for amplification, recall, logic discrimination and calculation operations
3. hydraulic actuator
The strengths of the hydraulic actuator are:
1. Simple structure, small volume
2, can output strength is large
3, due to hydraulic viscosity, can improve efficiency
4. Self-lubricating function and anti-rust function
5, can be long-distance active control
6. It can switch high speed and low speed to complete the speed change
Disadvantages are:
1, piping, repair is not very convenient
2. Hydraulic components and pipelines are easy to leak
3. The change of viscosity caused by the change of oil temperature
4, not suitable for various operations on the signal
According to the above, we can know that all kinds of valve actuators have their own advantages and disadvantages, but according to their own needs, they can still select suitable actuators. Through careful comparison, they will be able to find suitable valve actuators.
