The Bell & Gossett Circuit Setter Plus is a calibrated balance valve designed for pre-set proportional system balance. Since its introduction to the HVAC industry in 1968, the Bell & Gossett Circuit Setter has set the standard for proportionally balancing hydronic HVAC systems. This system balance method, developed by Bell & Gossett, assures optimum system flow balance at minimum pump operating horsepower. Valves can simply be pre-set using the B&G Circuit Setter Balance Valve Calculator, curve booklet G10091, or the System Syzer application for iPhone, iPad, or PC.
