Ensure consistent performance in your hydronic heating system with the Hoffman 402442 Series 2100 pressure reducing main valve. This 3/4" NPT component is engineered to automatically regulate water supply pressure, protecting your boiler and piping infrastructure from damaging spikes and maintaining optimal operating levels for longevity.
The Series 2100 valve functions by utilizing an internal diaphragm-actuated design that responds to downstream pressure changes. When the system pressure drops below the set point, the valve modulates to allow additional makeup water, ensuring a steady, reliable supply for efficient system operation.
Key System Performance Baselines:
- Precision Regulation: Maintains consistent downstream pressure levels for reliable hydronic performance.
- Robust Construction: Engineered to withstand the rigors of high-temperature heating systems.
- Easy Integration: Features a standard 3/4" NPT connection for seamless installation into existing supply lines.
⚠️ Application Profile: Ideal for professional hydronic heating contractors and maintenance facilities performing routine boiler system upgrades, pressure regulation maintenance, or new installations requiring dependable water makeup control.
