Electric control valve is widely used in electric power, chemical industry, metallurgy, environmental protection, water treatment, light industry, building materials and other industrial production areas, industrial automation is an important instrument indispensable. Because of its environmentally friendly and quick installation has won a large number of users of all ages. Electric control valve according to the shape, size, parameter specifications and specific applications are divided into different electric single-seat control valve, electric sleeve control valve, electric two-seat control valve, electric three-way control valve, electric small flow control valve, electric Angular control valve. Although different types, but the same as the electric control valve, they are a lot of commonality, users should refer to when purchasing a few things: First, look at the size, the real strength of the company to make the electric control valve, it should be the volume Relatively small, relatively light weight, material is relatively durable, the connection is relatively simple. Because with the development of science and technology, with the continuous improvement of performance, the material should be more and more light and more and more durable, and it should be used more and more simply. The material, shape and method of operation often expose the strength of a company. Second, look at the parameters of electric control valve and adjust the accuracy, tightness. For example, the design of nominal diameter, pressure range, the medium allows the temperature range, humidity range, flow characteristics, spool form, travel range, work speed and so on. According to their own needs to choose the right parameters. Then a very important point is to look after the sale. Auto parts industry, you can be bluntly said that the sale is to buy. Good manufacturers can provide 5-10 years of free maintenance, also provides a variety of technical support, in your installation and use of the encountered problems and doubts have a dedicated technical staff to answer, one of the best It is a giant valve industry. Finally suggest that you must go to the big manufacturers or companies to buy. Giant good valve industry, with a variety of quality system certification, but also has its own patent certificate, valve manufacturing has been walking in the forefront for many years, providing convenience for the majority of users with a wide range of services and services, the real realization The "German first, quality as the root, honest-based, letter-based" business purpose.
