Efficiently regulate hydronic system pressure with the Hoffman 402478, a robust Series 2100 pressure reducing main valve designed for demanding commercial and industrial applications. This 1-1/2" NPT component ensures consistent downstream pressure delivery, safeguarding your boiler equipment and piping infrastructure from damaging pressure spikes.

This valve utilizes a spring-loaded diaphragm mechanism that automatically compensates for fluctuations in supply pressure. By continuously monitoring the discharge side, it modulates the internal seat to maintain a stable, pre-set pressure, providing reliable performance in closed-loop heating or process water systems.

Key System Performance Baselines:

  • Automatic Regulation: Maintains precise downstream pressure settings despite varying supply conditions.
  • Durability Engineered: Constructed with high-grade materials to withstand continuous operational stress in hydronic loops.
  • Streamlined Maintenance: Designed for longevity and ease of service within established plumbing configurations.

⚠️ Application Profile: Primarily utilized in commercial steam and hot water boiler feed lines, industrial process temperature control systems, and centralized hydronic heating distribution mains where stable pressure is critical to system longevity.
