Xylem-Bell & Gossett 117107LF Circuit Setter Plus CB-3 Balance Valve 3" NPT Lead-Free

The Xylem-Bell & Gossett 117107LF Circuit Setter Plus is a lead-free calibrated balance valve that functions as a three-in-one precision instrument: a balance valve, a flow meter, and a drip-tight service valve. This valve is designed for pre-set proportional system balance, making it ideal for optimizing hydronic HVAC and potable water systems.

Key Features:

• Full port ball valve design with calibrated nameplate, memory stop, and two integrated pressure/temperature ports for easy measurement
• Brass body construction with EPDM trim and glass/carbon filled TFE seat ring
• 3" FNPT lead-free design with 400 PSI maximum working pressure
• Operating temperature range: -4°F to 250°F
• Dimensions: 6.5" inlet to outlet length, 5.12" width x 5.44" height
• Precisely calibrated for use as a presettable balance valve, variable orifice flow meter, and positive shut-off service valve

Since its introduction to the HVAC industry in 1968, the Bell & Gossett Circuit Setter has set the standard for proportionally balancing hydronic HVAC systems, ensuring optimum system flow balance at minimum pump operating horsepower. Valves can be pre-set using the B&G Circuit Setter Balance Valve Calculator, curve booklet G10091, or the System Syzer application.
