The Bell & Gossett 132121 is a heavy-duty, straight pattern Triple Duty Valve engineered to simplify hydronic system piping by combining four critical functions into a single, compact unit. Designed for commercial and industrial hydronic applications, this valve eliminates the need for multiple individual components, reducing installation time, labor costs, and potential leak points.
Four Functions in One Valve
- Soft Seat Nonslam Check Valve — prevents reverse flow and water hammer without slamming, protecting system components and extending service life
- Throttling Valve — allows precise flow control and system balancing during commissioning
- Calibrated Balance Valve — features a calibrated scale for accurate, repeatable flow measurement and adjustment
- Shutoff Valve — provides full isolation capability for maintenance and service without draining the system
