Abnormal situation:
Serial number | Abnormal phenomenon | reason | Troubleshooting method |
01 | The position of opening the valve is opposite to closing the valve | Wiring error | Change the valve opening line and the valve closing line |
02 | The actuator does not operate | Wiring error, the line burned out | Check the power supply and line thermostat |
Water inlet to the actuator or motor damage | Replace the actuator | ||
03 | Cracking at the threaded connection | The connection thread does not match, the installation is not standardized or the force is too large | Replace the valve body |
04 | The valve cannot be fully opened or fully closed | Pipe debris clogged, water quality is too poor | Clean up pipeline debris or install a pre-filter |
Installation precautions:
1 The actuator must be on the horizontal line;
2 Do not use strong force on the drive during installation;
3 The thread connected to the valve must be a standard international pipe thread (i.e. G thread). Do not use tapered
thread to connect to the valve;
4 The valves and pipes should be kept clean before installation, and there should be no debris;
5 The valve and pipeline should be installed horizontally or vertically, but not upside down;
6 Please ensure that the pipes and valves are kept warm, and the actuators must not be wrapped in the insulation
layer.
Remarks: If the product is damaged due to improper installation or harsh working conditions, our company only
provides paid services.
overview:
DQ220 series electric ball valve is suitable for on-off control of HVAC water system and consists of two parts:
electric drive and valve body.The drive (actuator) is driven by a synchronous motor, and the action is stable.The
built-in limit contact point can power off the valve when it is fully open or closed. The valve body is forged in brass
and the surface is nickel-plated.
Note: Under normal circumstances, the valve is installed in the normally closed position when it leaves the factory.If
you need another location, please specify.
