What kind of wire is used for the installation of pneumatic wafer type rubber lined butterfly valve? The butterfly valve is the actuator in the automatic control system, and its application quality directly reflects the regulation quality of the system. As a terminal component in process control, people have a newer understanding of its importance than in the past. In addition to the quality of the product itself, and whether the user correctly installs, uses, and maintains the butterfly valve, it is very important to correctly calculate and select the type of butterfly valve. Due to the error of calculation and selection, the system starts and stops, and some can not even be put into use. Therefore, users and system designers should understand the importance of valves on site, and pay enough attention to the selection of butterfly valves.
、 If the pneumatic butterfly valve can not reverse normally under the rated voltage, check whether the connector (plug) of the solenoid coil is loose or not in contact. The method is to unplug the plug and measure the resistance of the coil. If the resistance is too large or too small, the solenoid coil is damaged and should be replaced.
