Of the electrical control system of electric valve
Due to the requirements of industrial automation level is improved, on the one hand to the electric valves are being more and more, on the other hand has higher requirement for electric control valve, more and more complex.
So in the design of electrical control of electric valve is always updated.
With the improvement of science and technology of Shanghai valve and the popularization of computer applications, new, diverse electrical control methods will appear.
Overall control of electric valve, should pay attention to choose electric valve control mode.
According to the project need, for example, whether the application of centralized control mode, or single control mode, and other equipment, sequence control and application of computer order control, and so on, its control principle are different.
Valve electric device manufacturers are only sample standard electrical control principle, so the application department should with the consumption of electric equipment factory technical clarificaiton, clear technical requirements.
In addition, when choosing electric valve, to weigh whether additional purchase electric valve controller.
Because of the general status, the controller is need to purchase separately.
Most state, using a single control, is the need to purchase of the controller, because the acquisition controller is convenient, inexpensive than users to design and manufacture.
When the electrical control performance can't satisfy the engineering design requirements, shall be made to the consumption of plant to modify or redesign.
