Efficiently manage hydronic system flow and isolation with the Bell & Gossett 132122, a premium 3DS-2-1/2S Triple Duty Valve designed for industrial and commercial performance. This robust flanged valve serves three essential functions in a single body: acting as a shut-off valve, a non-slam check valve, and a flow balancing valve to optimize pump efficiency.
Engineered for precision control, the internal mechanism utilizes a calibrated position indicator and memory stop to ensure repeatable balancing settings after maintenance. The flow-optimized geometry minimizes pressure drop while preventing backflow and water hammer, ensuring smooth operation in complex hydronic circuits.
Key System Performance Baselines:
- Flow Regulation: Precision throttling for accurate system balancing and pump energy optimization.
- Backflow Prevention: Integrated spring-loaded disc design effectively prevents reverse flow and associated mechanical shock.
- Service Efficiency: Integrated isolation functionality allows for pump maintenance without the need for additional downstream valves.
⚠️ Application Profile: Recommended for use in chilled and hot water commercial HVAC loops, primary-secondary pumping systems, and pump discharge header isolation.
