Thermostatic Two Way Brass Motorized Ball Valve

Product summary

Brass Motorized Ball Valve(DQ220)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
