Ordering:
Setting Range:
The RAE-K and FEV-Z styles of thermostatic
operators provide an effective use of pressure
independent flow control with a non-electric
control valve. By using the ABQM pressure
independent control valve (PICV) proper
flow is maintained to the emitter. With the
thermostatic operator mounted to the valve, a
cost effective method of control is used to
maintain the room temperature.
The RAE-K thermostatic operators are a
series of valve mounted non-electric
operators that are capable of mounting to the
ABQM valve body. These operators are an
alterative to a motorized actuator providing a
temperature regulating within the room
either via built-in sensor or remote sensor.

Setting temperature range
RAE-K
The FEV-Z climate sensor is a
proportional controller which opens or
closes an AB-QM valve body as a function
of the temperature deviation. The wall
mounted non-electric operator can be
applied in climate systems with i.e.
ceiling-, floor- or radiator heating. The 6ft
capillary tube allows the placement of the
flush mounted setting/ sensing dial away
from the valve body.
When selecting these thermostatic
operators for an application, there is a
limitation in the ability of the thermostatic
operators to control the ABQM valve
body. The thermostatic operator is limited
to 30% of the maximum flow rate for the
ABQM valve sizes of ½” to ¾”.

with FEV-Z
Dimensions:
The FEV-Z sensor has been developed for heating regulation of water-based systems. The
FEV-Z sensor is based on the self-acting principle. The liquid-filled wall mounted sensor
control the valves via capillary tube.
When the knob has been set in the middle position the valve will open at temperatures
lower than 71°F (22°C). A setting in the red zone means the valve will open at a higher
room temperature. A setting in the blue zone means the room temperature will be kept at a
value lower then 71°F (22°C).
