QB Motorized Valve

QB Motorized Valve
General Features

ATLAS QB Series motorized Ball Valve consisting of actuator and valve body; It is used to control water in heating, cooling and air conditioning systems. Synchronous actuators to ensure stable operation and prolong life motors are adapted like a driver. Internal limit contacts ensure timely opening and closing of the valve actuator.

All of the valve bodies; It is made of brass, which is suitable for heating, cooling and air conditioning system applications.

NOTE: Generally, the valve is closed at factory default.
