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.
