The 3D-3S Triple Duty Valve serves as a critical component for hydronic heating and cooling systems, integrating isolation, throttling, and non-slam check functions into a single flanged unit. By streamlining piping requirements, the 132133 model 3D-3S reduces installation space while maintaining precise system balancing and protecting equipment from backflow.
This valve utilizes an internal disc design that provides a cushioned seating action to prevent water hammer during pump shutdown. Its calibrated throttling stem allows for accurate system flow adjustment, ensuring each loop receives the required water volume for maximum thermal efficiency throughout the facility.
Key System Performance Baselines:
- Drip-tight isolation: Provides reliable shut-off for localized maintenance without draining the entire system.
- Calibrated flow control: Features an adjustable memory stop for reproducible balancing settings after maintenance.
- Non-slam operation: Prevents hydraulic shock and noise within the hydronic loop through spring-loaded check action.
- Reduced footprint: Combines three distinct valve functions to minimize mechanical room piping complexity.
⚠️ Application Profile: Ideal for commercial HVAC pumping stations, chilled and hot water distribution loops, and vertical or horizontal piping configurations requiring integrated system balancing and backflow protection.
