Seeking expert advice on wiring electric valves
Thread Content
The Rotork electric valve is equipped with an HMV electric valve, an HMZT valve position transmitter, an HMS alarm input signal, and an HMI electric valve status signal; new diagrams have been added, but they’re a bit difficult to understand
There is no need for remote viewing of the image; the power supply of 220V AC is connected to the motor, while the control switch is connected to 24V DC. A temperature protection circuit connected in series is sufficient. You can ignore the rest if they’re not necessary. This valve is too unintelligent! It’s estimated to be all relay circuit boards
1\2\3 Valve power supply； 4, 5 Control power supply ； Display of control modes 42, 43, 44 ； 6, 7 Valve Closed Status Indication ； 8, 9 Valve Closed Indicator ； 33, 34, 35, 36 Remote control for opening and closing valves
For this electric valve, it is essential to determine whether it is powered internally or externally, as well as whether it operates in jog mode or hold mode. The DCS configuration must be set correctly so that the valve cannot move accidentally; one must also understand the wiring principle thoroughly. Make sure the battery is always charged; otherwise, once the power runs out, the previous settings will be lost and will need to be set again
