Cocon QTZ pressure independent control valve

Valve combination consisting of an automatically operating flow regulator (with a manually adjustable nominal value setting) and a control valve. The control valve can be equipped with an actuator, a temperature controller or a manual regulating head (connection thread M 30 x 1.5).

For installation in heating and cooling systems with closed water circuit (e.g. central heating systems, surface heating systems, fan coil systems, cooling ceilings, etc.) for automatic flow control (hydronic balancing) and also with the help of actuators, thermostats or temperature controllers for controlling another variable (e.g. the room temperature) by changing the flow rate.

Control range: 150-1050 l/h
Art.No.: 1145506
EAN: 4026755347517
