Valve’s working temperature

With external signal

If the valve is to be operated with an external signal, two set-

tings have to be made. One is as mentioned to the left, and the 

other determines how much the signal must be able to raise the 

temperature in the valve. This value is also read on one of the fol-

lowing curves.

Set the value in the r06 menu.

If the set value is too low, the valve will not be able to close/

open fully.

CVQ

KVQ

TQ

Without external signal

The working temperature must be set on the basis of one 

of the following curves. Find the actuator temperature cor-

responding to the required evaporating temperature (push). 

Set the value in the controller as mentioned under “Set the 

valve’s basic temperature reference”.

The two curves are shown with the valve’s spring setting equal-ling the factory 

setting. If the spring setting is changed to a higher pressure, the curve will be 

displaced correspondingly to a higher temperature.

CVMQ

Example

CVQ type = 0-6 bar

Refrigerant = R

717

A constant evaporating temperature or input pressure to the valve of -9°C (2 bar) is 

required.

According to the CVQ curve this will require a temperature in the actuator of 80°C. 

Set the valve’s basic temperature reference at 80°C.

When the valve has reached its working temperature, it may be necessary to fine-

adjust the setting from the system’s manometer.

All the curves shown are approximate.
