Description
Bell & Gossett 132126 – 6″ ANSI 125 Flanged Triple Duty Valve
The Bell & Gossett 132126 is a heavy-duty, straight-pattern Triple Duty Valve engineered to simplify hydronic system piping by combining four critical valve functions into a single, compact unit. With a 6-inch ANSI 125 flanged connection, cast iron body, and bronze seat, this valve is built for demanding commercial and industrial hydronic applications where reliability and space savings are paramount.
Four Functions in One Valve
The Bell & Gossett 132126 eliminates the need for multiple individual valves by integrating the following functions:
- Soft Seat Nonslam Check Valve – Prevents backflow quietly and reliably, protecting pumps and system components from reverse flow damage
- Throttling Valve – Allows precise flow adjustment to meet system design requirements
- Calibrated Balance Valve – Enables accurate hydronic system balancing for optimized energy efficiency and comfort
- Shutoff Valve – Provides full system isolation for maintenance or pump service without draining the system

Design & Application Benefits
Designed for large commercial hydronic systems, the 132126 reduces installation time and material costs by replacing multiple individual components with one precision-engineered assembly. The straight-pattern design ensures minimal pressure drop and straightforward installation in-line with pump discharge piping. The cast iron body provides long-lasting durability in closed-loop hydronic systems, while the bronze seat ensures a reliable, corrosion-resistant sealing surface.
The soft seat nonslam check feature is especially valuable in systems with variable-speed pumps, preventing water hammer and protecting equipment during pump start/stop cycles. The calibrated balance valve function allows technicians to set and verify flow rates with confidence, supporting ASHRAE and design-intent commissioning requirements.
