Laars Heating Systems RA2138604 Valve
The Laars Heating Systems RA2138604 Valve is a high-capacity boiler pressure relief valve designed for demanding commercial and industrial hydronic applications. Part of the Kunkle 740 series, this 1.5-inch NPT safety valve is engineered to provide precise overpressure protection for large-scale heating systems and water heaters. Featuring a fixed set pressure of 50 PSI and a massive discharge capacity of 4,237,000 BTU/hr, it ensures system integrity by automatically venting excess pressure to prevent vessel failure. The rugged bronze body and stainless steel spring construction are built to withstand high-temperature hydronic environments, making it a critical component for Laars commercial boilers like the Pennant or Mighty Therm series. As a veteran-grade HVAC safety relief valve, it meets strict ASME Section IV and VIII requirements, offering a reliable 740-1.5"-50# configuration that contractors trust for mission-critical pressure management.
Key Benefits- High Relief Capacity: Rated at 4,237,000 BTU/hr, providing sufficient venting for high-output commercial heating units.
- Industrial-Grade Construction: Features a durable bronze body and corrosion-resistant stainless steel internals for long-term reliability in harsh mechanical rooms.
- Precision Calibration: Factory-set at 50 PSI to ensure immediate response when system pressure exceeds safe operating limits.
- Code Compliance: Built to ASME Section IV and VIII standards, ensuring the part meets necessary safety regulations for pressurized vessels.
- Standard Connectivity: The 1.5-inch connection allows for straightforward integration into existing large-diameter piping assemblies.
What is the primary function of the RA2138604 relief valve?
This valve is designed to protect the boiler or water heater vessel from overpressurization by opening at 50 PSI to discharge water or steam, preventing potential equipment damage.
Can this valve be used for steam applications?
While the 740 series is versatile, this specific model is typically configured for hot water heating boilers and supply systems. Always verify the 4,237,000 BTU/hr rating against your specific system's heat input.
Is this a genuine OEM Laars part?
Yes, the RA2138604 is a genuine Laars Heating Systems component, often manufactured by Kunkle/Emerson to Laars’ exact technical specifications for high-capacity relief.
