Pneumatic solenoid valve manufacturer: How to achieve flow regulation of solenoid valve?

How to regulate the flow of solenoid valve? How to adjust? How do solenoid valves regulate the flow of import and export pipelines? This article is discussed with you by the solenoid valve manufacturer Shanghai Chuannai Valve Co., Ltd. If the pipe flow is regulated by solenoid valve.

First of all, it should be clear that solenoid valves only have two states: through-flow and off-flow, because the response speed of solenoid valves is very fast, both in milliseconds. The instantaneous suction of the solenoid valve is usually millimeter to centimeter, whether it is electromagnetic effect or inertia. According to the law of performance, the spool can not hover, let alone control at any position where the control valve sends out 4-20mA signal.

As early as the 1980s and 1990s, there were solenoid valve designers in Europe. By parallel connection of two, three, four or more solenoid valves with different calibers, dozens of flow control schemes could be realized.
