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.
The Bell & Gossett Circuit Sentry is a calibrated pressure independent flow limiting valve with a precision machined ball type shutoff valve, and commissioning measurement ports. The valve is designed for flow limiting-style balancing of both HVAC cooling and heating circuits; the valve is not for use in potable water systems. The use of the flow cartridge facilitates easy flushing of the piping upon commissioning the system.
Bell & Gossett’s Ultra Setter Pressure Independent Control Valves combine easy field adjustability with excellent flow control, making them the ideal energy efficient solution for your HVAC system. The unique GPM dial makes setting and changing the maximum flow a breeze. And the innovative valve design provides full stroke modulation irrespective of the pre-set maximum flow rate, all while maintaining 100% authority at all times.
