Controlli 3F Series Quick Start Manual

Three-way Mixing Globe Valves

USE

3F.. series valves are used to control fl uids belonging to the
group showed in the table in accordance to article 9 of 97/23/
CE (PED) directive, in air-conditioning, thermoventilation and
heating plants and in industrial processes; therefore, they cannot
