Functional description

The presettable thermostatic valve AQH maintains the differential pressure
at a constant value via the presetting cross-section and the regulating
cross-section of the valve. The valve authority amounts to 100% (a=1).
You can set the maximum volume flow with the help of the enclosed preset-
ting key.
For room temperature control, you can screw a thermostat or an actuator
onto the thermostatic valve.

100% (a=1)
During part load operation with
steady control (e.g. in combina-
tion with thermostats for room
temperature control), the valve
authority of the thermostatic
valve AQH amounts to 100 %
(a = 1) within the effective valve
stroke.
