The pressure independent control valve “Cocon QTZ” with automatic flow control

The pressure independent control valve “Cocon QTZ” is a compact valve combination for automatic hydronic balancing consisting of a flow regulator and a regulating valve. The nominal value of the flow regulator can be set with the help of a handwheel. The regulating valve can be equipped with an actuator, a temperature controller or a manual head (connection thread M 30 x 1.5). The “Cocon QTZ” is made of dezincification resistant brass. It can also be used for temperature control of appliances or sections of the system in chilled ceilings, fan coil units, convectors as well as central heating or surface heating systems.

“Cocon QTZ” PN 25 – The new generation:
