PRESSURE INDEPENDENT CONTROL VALVES
1.- The volumetric flow [l/h] can be found in the technical
documentation or in the SCHAKO design program.
2.- Selection of the optimum valve. The valve must be
operated at approx. 80% of its V
Wmax
.
NOTE
The valve and the actuator can be adjusted on site without
tools.
NOTE
The unit has no external condensate pan. The valves
must be thermally insulated on site.
