Caleffi’s QuickSetter+ manual balancing valve featuring a built-in visual flow meter takes the guesswork out of balancing hot water recirculation systems. An improperly balanced system can waste water and annoy occupants waiting for hot water. Pull the flow indicator bypass pin, adjust the flow while viewing the flow meter and release the pin for quick and accurate circuit balancing in commercial and residential systems. No instruments or reference graphs needed. The valve is IAPMO-certified low-lead brass and available in 1/2”, 3/4” and 1” sizes with two flow range options: 0.5-1.75 gpm or 2-7 gpm.
