How to detect when the Liquid Cooling Butterfly Valve circuit fails

Before checking for circuit faults, turn the manual knob for cooling Butterfly Valve a few times to see if water cooling Butterfly Valve can reverse normally under the rated pressure. If cooling water Butterfly Valve can reverse normally, then the circuit is faulty. When checking Butterfly Valve cooling system data center, use a meter to measure the voltage of the electromagnetic coil to see if it has reached the rated voltage. If the voltage of water cooling Butterfly Valve data center is too low, further check the power supply in the control circuit and the associated travel switch circuit.
