Kunkle Valve 0537-D01-HM0100 Valve
The Kunkle Valve 0537-D01-HM0100 is a high-capacity bronze safety relief valve specifically engineered for low-pressure hot water boilers, heat exchangers, and generators. This 3/4" x 1" FNPT valve is factory set at 100 PSI and carries ASME Section IV and XIII "HV" certifications, ensuring rigorous compliance for commercial and industrial hydronic systems. With a certified steam capacity of 2759 lb/h (2,758,900 BTU/h), it provides critical overpressure protection caused by thermal expansion or control failure.
Constructed with a B584 alloy 84400 bronze seat and a durable stainless steel spring, the Model 537 features an extra-heavy construction for extended service life in demanding mechanical rooms. The top-guided disc assembly includes a resilient seal for superior leak-free performance, while an isolating diaphragm shields internal working parts from corrosive discharge. A specialized pivot design between the disc and spring compensates for side thrust, maintaining precise alignment during high-velocity cycles. The heavy-duty plain lift lever allows for mandatory manual testing as required by the National Board.
Key Benefits for Contractors- ASME Section IV Certified: National Board certified with "HV" designator for code-compliant boiler overpressure protection.
- High BTU Capacity: Rated for 2,758,900 BTU/h to handle large-scale commercial hot water heating applications.
- Corrosion Resistance: Bronze body construction and SST spring materials prevent binding and scale buildup in hydronic systems.
- Resilient Seating: Integrated EPDM/resilient seals ensure a tight shut-off after 0537 series lift cycles, reducing nuisance weeping.
- Serviceable Design: Features an accessible side outlet for piped discharge and a rugged lever for routine safety valve testing.
What is the maximum operating temperature for the Kunkle 537?
This model is rated for a maximum temperature of 250°F, making it ideal for standard hot water supply and heating applications.
Can this valve be used for steam heating boilers?
While the capacity is rated in steam (lb/h), this specific Kunkle 537-D01-HM is designed for hot water boilers under ASME Section IV. For pure steam heating applications, verify your local code requires Section IV or Section VIII "UV" stamping.
Is the set pressure adjustable in the field?
No, safety relief valves are factory set and sealed to prevent tampering. Field adjustments will void the ASME certification and compromise system safety.
