B&G 117106LF – CB 2-1/2″ NPT Bronze Circuit Setter & Balancing Valve
Bell & Gossett model CB-2-1/2 2-1/2″ IPF circuit setter with a NPT connection and straight pattern balancing valve. Circuit setter balancing valves offer positive shut-off, a memory stop indicator, and integral, valved readout ports. These valves are designed to provide optimum system flow balance at minimum pump operating horsepower. Using a circuit setter calculator allows the user to plot and preset the valve to various settings while figuring in head loss versus flow. The valve features an adjustment knob with memory stop indicator for settings as well as read-out ports which allows a read-out meter to be attached, in turn displaying feet of water.
