Cocon QTZ Valves up to DN 32

Pressure independent control valve for dynamic hydronic balancing of heat exchangers, for example fan coils or cooling ceilings and distribution pipes in heating and cooling systems with closed circuits. The valve combination consists of an automatically operating flow controller and a control valve and can be equipped with an actuator or a manual regulating head. Installation in the supply or the return pipe.
Two-way valve, with secured, lead sealable, infinitely adjustable flow limitation. Direct setting in litres per hour. Readability of the set value independent of the handwheel position. Valves with blind plugs can be retrofitted with Classic measuring valves. All DN 15 and DN 20 valves are suitable for copper pipe.
Valve body and parts coming into contact with the medium made of dezincification resistant brass, plastic, stainless steel, EPDM or PTFE. Maintenance-free spindle sealing.
Cocon QTZ are characterised by easy adjustability, compact dimensions and best control quality.

Suitable connection fittings see section “Connection technology”.
