Daily maintenance and management of electric valves

Both electric actuators and pneumatic devices have their own characteristics; let’s start by describing the pneumatic devices first. Pneumatic devices have three notable advantages: 1. They can handle large loads and are well-suited for applications that require high torque output. That being said, electric actuators are now also capable of handling significant loads and can match the performance levels of pneumatic devices; therefore, this point is provided only for reference, as circumstances vary from case to case. 2. Compared to other types of devices, pneumatic systems have lower requirements regarding the working environment; they can be used in flammable and explosive areas, as well as in many harsh environments such as those with high dust levels, strong magnetic fields, intense radiation, or severe vibrations. 3. The pneumatic device operates quickly, with a very fast response time. The advantages of electric actuators are mainly reflected in the following aspects: 1. Compared to other devices, electric actuators have a smaller size. Due to their simple structure, few components, and compact design, they are small in size and easy to assemble. 2. In terms of the requirements for the drive source, electric actuators have a clear advantage over pneumatic devices. Since electric actuators have simple requirements regarding the power source, the onboard power supply is generally sufficient as a driving source for them. In contrast, pneumatic devices require an air supply and a compression drive unit to function, which is clearly much less convenient. 3. Electric actuators do not require external power to maintain the load, whereas pneumatic devices need a continuous supply of pressure in order to do so. It is for this reason that electric actuators are relatively quiet during operation, as they lack any additional pressure mechanisms; in contrast, pneumatic devices generate significant noise due to the need for an external pressure source. When handling heavy loads, an additional silencer is required to reduce noise levels.
