Icma C300 | Calibration and balancing valve with threaded connections and self-sealing measuring sockets for heating

The C300 static balancing valve allows precise and gradual regulation of the flow
rate. By turning the adjustment handwheel, the pressure drop and, consequently,
the desired flow rate can be set.

Function

Art. C300 is equipped with a mechanism for setting
the maximum valve opening for the purpose of
pre-setting. This mechanism limits the travel of the
knob (ref. C) by means of a locking screw (ref. B).
Pre-setting requires:
• Choose the design flow Q as a function of the
differential pressure Δp;
• Using the diagram below, determine the
adjustment to be made to obtain the design
flow Q as a function of differential pressure Δp
depending on the valve size;
• Adjust the valve by means of the knob (ref. C)
on the adjustment scale (ref. A);
• Tighten the pre-setting locking screw (ref. B)
clockwise as far as it will go using a 3 mm Allen
key
