Product Description
HVAC Motorized Ball Valve (DQ220)

1, Product summary
DQ series of motorized ball valves are used to control the on/off of the water system in HVAC system, consisting of actuator and valve body. Actuator (driver) adopts synchronous motor driver for its stable performance. Internal limit contacts and energy saving design in valve, can cut off the power when the valve is fully opened or closed.
We suggest you use this product together with our thermostats, such as tc45W, tc43W, tc41W, ckn301dw, ckn101, ckn301 and ckn700 series of thermostats.
Remark: Generally, the default state of valve door is normally closed. If you have any special request, please let us know.
