Bell & Gossett Circuit Setter Plus Calibrated Balance Valves

Fast, Reliable Connections with the Performance You Trust

The Bell & Gossett Circuit Setter® Plus from Xylem is now available with Press Connect fittings, offering a faster, cleaner, and safer installation option compared to traditional National Pipe Thread (NPT) and Sweat (SWT) connections.

Designed to work with all major press/crimp tool brands, these integrated fittings help streamline installation, improve jobsite efficiency, reduce labor time, and minimize material waste - while maintaining the dependable performance Bell & Gossett is known for.

The Circuit Setter Plus is a calibrated balance valve used for pre-set proportional balancing in hydronic HVAC systems. Since its introduction in 1968, it has been recognized as an industry standard for achieving proper system flow while helping reduce required pump horsepower. Bell & Gossett’s proven balancing method supports consistent system performance, improved energy efficiency, and reliable flow control across a wide range of applications.

Available in cast/ductile iron and lead-free brass construction, Circuit Setter Plus valves are ideal for HVAC and potable water balancing applications. With the addition of Press Connect fittings, they now combine long-standing reliability with modern installation convenience.
