With the rapid development of Chinese industry, the application of electric control valves in fields such as metallurgy and petrochemical industry is becoming increasingly widespread. Its stability and reliability are also becoming increasingly important. The quality of its working state will directly affect the automatic control process. Below, let's follow the editor of De Cologne to learn about the use and maintenance of electric control valves.
Electric control valves are highly valued in the industrial industry, and their existence has driven the progress and development of many industries. With the increasing level of automation in the industrial field, it is being increasingly applied in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: electric control valve saves energy (only consumes electric energy when working), environmental protection (no carbon emission), and quick and convenient installation (no complicated pneumatic pipeline and air pump workstation is required). Valves are divided into three types based on the power used by the actuator they are equipped with, including linear characteristics, equal percentage characteristics, and parabolic characteristics.
The electronic electric single seat regulating valve is composed of a straight stroke fully electronic electric actuator and a top guided straight low flow resistance single seat valve. It is compact in structure, light in weight, sensitive in action, S-streamlined in fluid channel, small in pressure drop loss, large in valve capacity, and accurate in flow characteristics. It can control operation by directly receiving control signals such as (4-20mA DC 0-10mA DC or 1-5V DC) input from regulating instruments and single-phase power supply, realizing automatic regulation and control of fluid medium in process pipeline. It is widely used to accurately control process parameters such as pressure, flow Maintain parameters such as temperature and liquid level at the given values.
