The circuit setter was developed by Bell & Gossett so as to ensure an optimum flow balance of water.

This plumbing valve is used to regulate the flow of water.

What was the purpose of the Bell and Gossett circuit setter?īell & Gossett Circuit Setter Plus has revolutionized the plumbing system. It ensures saving of water by equal flow throughout all the circuits. This revolutionized system is meant for HVAC industry. There are several sizes of circuit setter plus, but you can buy a right setter by evaluating the adjustment range of valve and test ports available on the circuit setter. What do you need to know about a circuit setter? When it comes to plumbing, a circuit setter valve is used to optimize the pressure between hot and cold water within the potable water system. How is a circuit setter valve used in plumbing? This has been introduced to HVAC industry to ensure the optimum flow of water and accurate measurement. It is a calibrated balance valve that ensures the balanced flow. These have been around for a while and are what most people commonly refer to as “circuit setters.” Calibrated balancing valves are designed for pre-set proportional system balance. MODEL NO.Is a balancing valve the same as a circuit setter?Ĭalibrated Balancing Valves. Valve to be leak-tight at full rated working pressure. All valves to have calibrated nameplates to assure specific valve settings. Valves to have memory stop feature to allow valve to be closed for service and then reopened to set point without disturbing balance position. Valve bodies to have 1/4" NPT tapped drain/purge port. Read-out ports to be fitted with internal EPT inserts and check valves. Valves to have differential pressure read-out ports across valve seat area. Pump impeller trim after system balance will reduce system horsepower and operating costs to minimum levels.Īll valve to be of bronze body/brass ball construction with glass and carbon filled TFE seat rings. NOTE: SAFETY INSTRUCTION: This safety alert symbol will be used in this manual to draw attention to safety related instructions. With this procedure, system balance and start-up time is reduced dramatically.

Terminal Unit balance valves can be simply pre-set using the B&G Circuit Setter Model RF Curves and the system piping plan. This system balance method, developed by B&G, assures optimum system flow balance at minimum pump operating horse power. The CIRCUIT SETTER Model RF calibrated balance valve is designed specifically for pre-set or proportional system balance for use with terminal and fan coil units.
