Cocon QTZ Pressure independent control valves DN 10 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.
Two-way valve, with secured, lead sealable, infinitely adjustable flow limitation. Direct setting in litres per hour. Readability of the set value possible from the outside, independent of the handwheel position, even with the actuator mounted. Valves with blind plugs can be retrofitted with Classic measuring valves. All DN 15 and DN 20 valves with internal thread are suitable for copper pipe with compression fittings.
Valve body and wetted parts made of dezincification resistant brass, plastic, stainless steel, EPDM or PTFE. Maintenance-free spindle sealing.
Cocon QTZ are characterized by easy adjustability, compact dimensions and best control quality.
