Relief Valve Adjustment, Assembly, and Testing Basics

Rick Walker talks with Ritchie Ware today about how a relief valve works. Rick describes ring adjustments that give the valve lift and blow down. If the ring adjustment is not properly set the relief valve will not function. All springs have their own range so when you repair a valve you have to consider selecting a spring that meets the appropriate functional ranges. Power boilers 400 PSI or below should be tested annually. It is recommended that you test relief valves every 6 months.

Rick and Ritchie assemble a relief valve and name the parts as they assemble it. In part two of this video Rick will show how to test relief valves.
