2 way brass valveelectric actuated floating For air conditioning pvc motorized ball valve
QB SERIES MOTORIZED BALL VALVE
QB Series Motorized Ball Valve, which is composed of actuator and valve body, is used to control HVAC water system. And the actuator, adopting synchronous motor as driver, operations stably. And the inbuilt limit contacts make the valve power off when the valve open or close. And the valve body is forged by brass, which is suited for motorized ball valve in air conditioning.
NOTE: Generally, the valve is installed on normally open position.

Simple Exception Handling:
Code | Phenomenon exception handling | Reason | Handling |
01 | Open valve and close valve is in opposite position. | Wiring is wrong. | To change the wiring of the open valve and close valve. |
02 | Actuator doesn’t work. | Wiring is wrong or circuit is burned or there are water in the actuator or motor is damaged. | Check the power supply and circuit and thermostat. |
Replace the actuator. | |||
03 | Thread connections are cracked. | The connecting thread is not matched. Or the installation is irregular. Or force is too large. | Replace the valve body. |
04 | The valve can not open or close fully. | Pipes clogged or poor water quality. | Clean the debris in the pipes or install pre-filter. |
Installation Notices
1.The actuator should be installed on the horizontal line.
2.Do not use too much force on the actuator during installation.
3.The thread to connect the valve should be the standard international pipe thread(pipe thread G). Do not use taper thread to connect the valve.
4.Keep the valve and pipes clean before installation.
5.The valve and pipes can be installed horizontally or vertically, but do not install them on invert position.
6.To make sure pipes and the valve keep warm, but do not keep the actuator inside insulation layer
