The CVQ valve is operated by the EKC controller. Please notice that a power failure will cause the CVQ pilot valve to fully open ICS / PM. If it is required that. Type Code, EKC Weight, Kg.

Precise media temperature control

In the control menu, not only are basic adjustable values displayed, but it is also possible to precisely influence certain events by adjusting stability and amplification factors. The “EKC ” control has three different transient processes available. This can be done using special software type “Danfoss AKM”. Page of 16 Go.

Page 8 If you need to return to the factory-set values, it can be done in this way: If the actual application has a requirement re- garding max. Don’t show me this message again. The actual value of this actuator temperature and the current reference value can be read in the control menu of “EKC ” “”. In simple terms, the purpose of the drip-off time is to drain off ice that has turned into water on the evaporator via the condensate drain.

B – Product specifications

In the case of hot gas defrosting, the “KVS” valve closes during the defrosting procedure. Got it, continue to print. The “D component” in PID control also optimises the control characteristics in the case of danfods sudden change to the reference value. Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material.


A defrost sensor in the dajfoss package ends the defrosting process as soon as the temperature of the evaporator package has reached the temperature to which the sensor is set. Page 4 S according to entered setpoint. All parameter values that begin with “u” display actual plant values which are important for all types of troubleshooting and for evaluating the state of the plant.

Precise media temperature control.

However, with “CVQ” an actuator is used to operate the valve instead of a stepper motor. The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided.

EKC – Documents

It is a direct operating and pressure independent valve for control- ling media temperatur. Don’t have an account? Of course, it is also the case damfoss that the dew point for dehumidification must always be undershot. Even with a temperature difference of just 1 K, the control forces a small opening to prevent the control from overshooting the set point. For safety, a maximum defrost duration can also be set in the refrigeration controller, which ends the defrosting process in the case of a defective defrost sensor or a similar fault.


A fast-reacting temperature sensor e. This is a good troubleshooting aid.

This is an advantage, particularly where the release of high pressure and, if necessary, liquid in the evaporator are concerned. If more than kohm is measured across terminals 17 and 18 disassemble the Actuator feels warm. The controller is operated using two push buttons. This also applies to products already on order provided that such alternations can be made without subsequential changes being necessary in specifications already agreed.

Page 5 Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page To print the manual completely, please, download danfosss. Defrosting The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact.

If connection sizes larger than 54 mm are required for the suction line, it is recommended that you implement a solution with a main valve. This means that any fitter at the plant can intervene in the control circuit and view relevant data.

This valve is equipped with a stepper motor and is controlled by an electronic controller e. Comments to this Manuals Your Name. The individual status codes have the following meanings:
