Barberi® BS5 motorized rotor zone valves are used in the zone management of heating and air conditioning systems. They are used in central heating systems, wall-mounted boilers, solid fuel generators and heat pumps. The valve body features the Soft-Torque technology, characterized by a patented design and very low friction materials, which allow a fast and smooth rotation in 8 seconds only. The fast clip coupling, the knob for manual operation, the auxiliary microswitch, the integrated cable, the general compactness, the ergonomic design and the low resistant torque make the BS5 line an easy to use and high energy saving product. The 3-way valve can also be used as diverting valve since the AB-A and AB-B ways have the same flow coefficient Kv. The 2-way valve is bidirectional (indifferent flow direction). The ARP version with green cover features an Automatic Return in Position function (ARP) by means of an electric supercapacitor. This makes the valve operation and use more advantageous than traditional mechanical spring return actuators, with energy savings up to 90% in the open position.
