Thermostatic valve "AQ"
DN 20, PN 10, angle pattern

Thermostatic radiator valve "AQ" for automatic hydronic balancing

For use in two pipe central heating and cooling systems with circulation pump.

Pressure independent thermostatic radiator valve with infinitely adjustable presetting. The nominal value is set with the help of a presetting key and turning the handhweel. The control range is visible from outside. As for the valves with "Q-Tech", the volume flow which is maintained even where high differential pressure variations occur, is set directly.

The valve insert is replaceable without draining the system and fits all standard thermostatic valve bodies manufactured since 1999 (M 30 x 1.5).

All valves of the "AQ" have a light grey protection cap.

Thermostat connection thread: M 30 x 1.5.

Flow range: 10 - 170 l/h Differential pressure control range: 0.1 bar - 1.5 bar
