Balancing valves are hydraulic devices that can precisely control the flow rate of the

fluid that supplies a system’s emitters. Hydraulic circuits must be correctly balanced

to ensure that the system operates at the design conditions and provides a high level

of heat comfort with low energy consumption.

For the 130 series valves, the flow rate is measured by a Venturi port designed into

the body of the valve. This guarantees accurate setting as well as ease of use during

calibration.

SAFETY INSTRUCTION This safety alert symbol will be used in this manual to draw attention to safety related instructions. When used, the safety alert symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN A SAFETY HAZARD. CAUTION: All work must be performed by qualified personnel trained in the proper application, installation, and maintenance of systems in accordance with all applicable codes and ordinances.

Operating Principle The opening position is indicated by two numbered indicators (fig. E): - The turn indicator (1) shows a flow rate scale from 0 to 6 (0 closure, 5 maximum flow rate, 6 completely wide open flow) in red. Turning the knob manually through 360° causes the indicator to click by one unit. - The micrometric control indicator (2) shows numbers in black from 0 to 9. Each change in this number represents 1/10 of an opening/closing turn of the valve with respect to the turn indicator (1).

a) As the thermal fluid passes, measure the Δp of the valve wany suitable differential pressure measuring device(fig. G); b) Using the “Hydraulic characteristics” sheet (sheet code 18169 supplied in the pack), find the flow rate value that is passing through the valve, consulting the Venturi diagram “Δp-flow rates” corresponding to the size of the valve used. c) Turn the knob and repeat steps a) and b) until you reach the desired value.

Locking/sealing the setting position (fig. I) I L 10 Installing Insulation Apply the insulation and close with the Velcro (10) already installed (fig. L). M For installations with chilled water, seal with suitable adhesive (fig. M). N Maintenance If broken, the knob of the valve can be replaced. - E xtract from the adjusting knob assembly the two parts (11) and (12) that make up the knob.

CAUTION: If the balancing valve valve is not installed, commissioned and maintained properly, according to the instructions contained in this manual, it may not operate correctly and may endanger the user. CAUTION: Make sure that all the connecting pipework is water tight. Caleffi North America, Inc. 3883 West Milwaukee Road Milwaukee, WI 53208 T: 414.238.2360 F: 414.238.
