Laars Heating Systems RA2138702 Valve

Laars Heating Systems RA2138702 Valve

The Laars Heating Systems RA2138702 Valve is a high-capacity boiler pressure relief valve engineered for demanding commercial and residential hydronic applications. This 1x1.25 inch relief valve features a precise 75 PSI pressure rating and an impressive discharge capacity of 2,649,000 BTU/hr, making it a critical safety component for large-scale heating plants. Designed to prevent over-pressurization, this HVAC replacement part ensures system integrity by providing reliable mechanical venting when thermal expansion exceeds the set point. As a genuine Laars boiler part, it offers exact dimensional compatibility for 1" inlet and 1.25" outlet piping configurations, maintaining the specific flow coefficients required for safe operation. For technicians performing furnace repair or boiler maintenance, selecting this ASME rated relief valve is essential for meeting local mechanical codes and protecting heat exchangers from catastrophic failure. Its robust construction is optimized for high-temperature water systems where consistent calibration and durability are non-negotiable.

Key Benefits
  • High BTU Capacity: Rated for systems up to 2,649,000 BTU/hr, suitable for high-output commercial boilers.
  • Precise Pressure Management: Factory-set at 75 PSI to provide accurate over-pressure protection without premature weeping.
  • Heavy-Duty Construction: Built to withstand the rigorous thermal cycling common in industrial hydronic environments.
  • Oversized Outlet: Features a 1.25" outlet to ensure unrestricted flow during full discharge events.
Common Questions
  • What size are the connections on the RA2138702? This valve utilizes a 1-inch NPT inlet and a 1.25-inch NPT outlet for high-volume discharge.
  • Can this be used on a residential water heater? While compatible with high-capacity systems, always verify the BTU rating and PSI limit of your specific equipment before installation.
  • Is this valve ASME certified? Yes, this relief valve is designed to meet stringent industry safety standards for pressure-relieving devices in heating applications.
