Description
The Bell & Gossett 132122 is a straight-pattern Triple Duty Valve engineered to consolidate three essential hydronic system functions into a single, compact inline assembly. Featuring a 2-1/2″ ANSI 125 flanged connection and a cast iron body with a bronze seat, this valve is designed for dependable, long-term performance in commercial and industrial hydronic heating and cooling applications.
Three Functions in One Valve
The 132122 combines three critical hydronic circuit functions, eliminating the need for separate components and reducing installation time, material costs, and potential leak points:
- Soft Seat Nonslam Check Valve — Prevents reverse flow with a quiet, water-hammer-free design that protects pumps and system components from backflow damage
- Throttling Valve — Allows precise flow adjustment to balance system circuits and optimize hydronic performance
- Calibrated Balance Valve with Shutoff — Provides accurate, repeatable flow balancing with a built-in shutoff capability for system isolation during maintenance or commissioning
