DN 20, G 1, 150 - 1050 l/h, with two mounted Classic measuring valves and mounted measuring orifice, DZR brass

"Cocon QTZ" Pressure independent control valve (PICV) with mounted measuring orifice and pressure test points "classic" measuring technique

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

For installation in heating and cooling systems (e.g. central or underfloor heating systems, fan coil units, chilled ceilings, fan convectors etc.) with closed circuits for automatic flow control (hydronic balancing). It can also be used for the control of another variable (e.g. room temperature) by modifying the flow rate with the help of actuators, thermostats or temperature controllers.
