RAE-K	FEV-Z

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.

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-, flooror 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”.

	RAE-K, FEV-Z
Temperature	The FEV-Z sensor has been developed for heating regulation of water-based systems. The
control	FEV-Z sensor is based on the self-acting principle. The liquid-filled wall mounted sensor
with FEV-Z	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).
