Ensure consistent and efficient pressure regulation in your hydronic heating system with the Hoffman 402409 Series 2100 pressure reducing main valve. This 1-1/4" NPT component is engineered to provide precise control over water feed pressure, safeguarding your boiler and piping infrastructure from damaging spikes while ensuring peak performance.

The valve operates using a spring-loaded diaphragm mechanism that automatically compensates for fluctuations in supply pressure. As downstream pressure drops, the valve opens to restore the set point, maintaining a stable operating environment for the entire system loop.

Key System Performance Baselines:

  • Automatic Pressure Regulation: Maintains consistent system filling to prevent cavitation and air binding.
  • Robust Construction: Designed for long-term durability in high-demand hydronic loops.
  • Precision Connection: Features standard 1-1/4" NPT threading for seamless integration into existing piping.

⚠️ Application Profile: Ideal for commercial and industrial boiler feed applications, closed-loop hydronic heating systems, and make-up water lines where precise pressure management is critical for operational longevity.
