General

The pressure independent control valve “Cocon QFC” is designed to be installed in heating and cooling systems with closed water circuit (e.g. central heating systems, surface heating systems, fan coil units, chilled ceilings and fan convectors) for automatic flow control (hydronic balancing). It can also be used for room temperature control by modifying the flow rate with the help of actuators.

Features

•   presetting of the nominal values even with mounted actuator
• optical display of the set nominal value even with mounted actuator
• excellent optical display of the presetting in any installation position
• nominal values can be read off in m3/h without conversion
• presetting can be locked and lead sealed
• constant high valve authority
• installation can be optimised by measuring the regulating pressure
• linear characteristic line if actuator driven
