Application

Here the controller has been specially 

designed for the following functions:

Maintenance of a constant 

evaporating pressure

A temperature sensor in the valve’s actuator will 

regulate its temperature. This temperature is 

an indication of the pressure in the valve, and 

the interface module will keep this temperature 

constant.

The media temperature is regulated 

by a PLC or similar device

Here the interface module receives a variable 

signal from the PLC and will subsequently  

regulate the valve, so that the refrigeration will 

be as accurate as possible.

The controller is used for regulating a valve in 

a refrigerating system - for example in 

connection with:

•   Long-term storage of fruits and vegetables

•   Refrigerating plant

•   Brewery systems

•   Processing plant

PLC
