Kunkle Valve 0537-G01-HM0050 Valve
The Kunkle Valve 0537-G01-HM0050 (interchangeable with 537-G01-HM0050) is a high-capacity ASME Section IV relief valve engineered specifically for hot water boiler and steam heating equipment. Featuring a 1 1/2" Female NPT inlet and a 2" Female NPT outlet, this valve is factory-set at 50 PSI to provide critical overpressure protection. The bronze construction and B584 alloy 8440 seat ensure durability under high-temperature conditions, while the stainless steel spring (SST) maintains consistent set-pressure integrity. With a thermal capacity of 5,112,244 BTU/h and a steam flow rate of 5112 lb/h (PPH), it serves a dual purpose by relieving pressure from both thermal expansion and over-firing conditions. Its top-guided disc assembly includes a resilient seal for leak-free operation, and the heavy-duty lift lever allows for mandatory manual testing by service technicians to verify system safety.
Key Benefits
- High-Capacity Discharge: Delivers over 5 million BTU/h capacity, meeting National Board certification standards for large-scale boilers.
- Superior Material Integrity: Utilizing a B584 alloy 8440 seat and corrosion-resistant stainless steel spring, this valve is built for long-term service in demanding boiler rooms.
- Dual-Purpose Protection: Effectively manages overpressure caused by standard thermal expansion or catastrophic control failure leading to over-firing.
- Maintenance-Ready Design: Equipped with a heavy-duty lift lever and an isolating diaphragm that protects internal working parts from contact with discharged fluids.
Common Questions
Is the 0537-G01-HM0050 suitable for both steam and hot water?
Yes, as an ASME Section IV "HV" rated valve, it is designed specifically for low-pressure steam and hot water heating boilers.
What is the difference between the 0537 and 537 model numbers?
The 0537-G01-HM0050 is identical to the 537-G01-HM0050; the leading zero is used for electronic inventory and cataloging purposes.
Can the set pressure be adjusted in the field?
This valve is factory-set and sealed at 50 PSI to comply with safety codes. Field adjustments should only be performed by a certified VR-stamp facility to maintain its certification.
