The Cocon QTZ Pressure Independent Control Valve is a valve combination consisting of an automatically operating flow regulator with a manually adjustable nominal value setting and a control valve.

Designed for use in heating and cooling systems with closed water circuits, the valve provides automatic flow control and hydronic balancing. It is suitable for applications including central heating systems, surface heating systems, fan coil systems, cooling ceilings, and other HVAC installations.

The control valve can be fitted with an actuator, temperature controller, or manual regulating head with an M 30 × 1.5 connection thread. This allows the flow rate to be adjusted to control other variables, such as room temperature.

The valve has a 300–2000 l/h control range and features an Rp 1″ internal thread. The supplied combination includes two mounted Classic measuring valves for commissioning and system measurement.
