Bell & Gossett 132123 3″ ANSI 125 Flanged Triple Duty Valve, 670 GPM, Cast Iron

Description

Bell & Gossett 132123 Straight Pattern Triple Duty Valve Overview

The Bell & Gossett 132123 is a heavy-duty, straight-pattern Triple Duty Valve engineered for hydronic piping systems where space efficiency and reliable performance are critical. By combining four essential valve functions into a single, compact body, this valve dramatically reduces installation time, minimizes potential leak points, and simplifies system maintenance — making it a go-to solution for commercial and industrial hydronic applications.

Key Features

• 3″ ANSI 125 flanged connections for straightforward integration into standard piping systems
• Cast iron body construction for long-lasting durability in demanding hydronic environments
• Bronze seat for corrosion resistance and reliable sealing performance
• 670 GPM maximum recommended flow rate to handle high-capacity hydronic systems
• Straight pattern design for simplified installation and reduced pressure drop
• Soft seat, non-slam check valve prevents water hammer and backflow damage
• Integrated throttling valve for precise flow control and system balancing
• Calibrated balance valve with visual flow indication for accurate system commissioning
• Built-in shutoff valve for convenient system isolation during maintenance

Four Functions in One Valve

The Bell & Gossett 132123 Triple Duty Valve consolidates four critical hydronic system functions into a single unit:

• Non-Slam Check Valve: Soft seat design prevents backflow without the water hammer associated with traditional swing-check valves
• Throttling Valve: Enables precise flow restriction to achieve design flow rates throughout the system
• Calibrated Balance Valve: Graduated scale allows technicians to set and verify flow balance during commissioning and service
• Shutoff Valve: Full isolation capability for pump removal, maintenance, or system service without draining the entire system
