Setting

DN 15-50

.  Unscrew the fixing screw (4) - Allen key 2 mm - on setting 

  wheel ().

2.  Turn the setting wheel clockwise to increase the differential 

  pressure and vice versa.

3.  On the setting wheel there is a mark which shows how 

  much 

D

p changes at one turn of the setting wheel. 

4.  The pressures can be controlled through pressure gauges 

  on the pipeline.

5.  After required differential pressure 

D

p is reached, tighten 

  the fixing screw on the setting wheel. 

6.  It is also possible to secure the setting with the leaden seal 

  - use holes on the body (8) and the setting wheel (9).

DN 65-125

.  Principle is the same as DN 5-50, except there is no mark 

  which shows how the 

D

p changes at one turn of the setting 

  wheel and also there is no fixing screw and no leaden seal 

  to secure the setting.

2.  The setting wheel (0) moves indirectly by the middle nut 

  (), which is turned by the batons supplied with the 

  controller.

3.  The pressures can be controlled through pressure gauges 

  on the pipeline.

p = min

p = max

Sizing

Select the size according to maximal speed. To prevent noise, maximal speed should not exceed 2 m/s in residential buildings 

and 3 m/s in industrial buildings. Control the pressure drop in the valve by formula:  

D

p = 00 x q

/ Kvs

2

 [kPa], where q is flow in m

3

/h.
