2003-7-29 · Specifically, the inlet line to the safety valve. What's happening is if the system sees an overpressure the safety valve opens (fully, assumes a true safety valve with huddling chamber). The valve will remain open as long as it is at app. 90% full capacity. If the line sizing restricts this flow the valve closes. Pressure builds, it opens fully.

Data Supplement for Kunkle Safety and Relief Products

Hot Water Boilers Safety valve must be set to relieve at a pressure not greater than the MAWP of the boiler. If more than one safety valve is used, the secondary valve(s) may be set up to 6 psig 0.41 barg above the MAWP for boilers with MAWPs up to and including 60 psig 4.13 barg, and 5% for boilers with MAWPs greater than 60 psig 4.13 barg.
