Description
The Bell & Gossett 132206 Triple Duty Valve (model 3DV-2NMF) is a premium hydronic system component engineered to consolidate three essential valve functions into a single, compact unit. Designed for commercial and residential hydronic heating and cooling systems, this valve simplifies installation, reduces potential leak points, and saves valuable mechanical room space.
With a 2″ Male NPT inlet and 2″ Female NPT outlet, the 3DV-2NMF integrates seamlessly into standard piping configurations. The durable brass body and chrome-plated brass ball deliver long-lasting corrosion resistance and reliable performance in demanding hydronic environments.
Three Valves in One
The Bell & Gossett Triple Duty Valve combines three critical hydronic functions:
- Combination Balance Valve – Allows precise flow balancing to ensure proper system design flow rates and optimal energy efficiency across all zones
