In the production process, the electric actuator is widely used, to the role of the people is very large, but many of my friends in the purchase process without knowing its purchase method, leading to the emergence of various problems occur during use. The main reason to buy improper because a lot of people in order to be cheap, not to the electric actuator monopoly were to buy, but just at the point of sale directly select a purchase, it's the quality itself, there are some problems, buy them back service is not perfect, ultimately resulting in a series of problems. Therefore, we buy electric actuator is should consider the following factors. In the purchase of electric actuators drive energy when we can start to make the purchase, the driving energy market are two main power source and fluid, if choose power, belonging to the large size of the valve if we should choose three power supply, so that the course was relatively safe, if it is a small size valve, we can choose a single-phase power supply. Another type of power divided into many, when we buy according to their actual situation to buy. Electric actuator valve is a very important part, we must first find out about the types of valves on before purchase, when to buy can choose to suit the type of actuator mechanism. Depending on the valve, the selected drive is not the same, these are directly related to the normal use of electric actuators. Can be given according to the manufacturer's data sheet select the type of electric actuators, but also note that some time after all the parts have to choose a good speed valve operation, and how often.
