Question about Ingersoll Rand - Rand Type - 30 Reciprocating Air Compressor - 7.5 Hp, 230 Volt 3 Phase, Model - 2475N7.5
NRV's and discharge valves often fail due to dirt and oil carry over. Carbon build up can cause problems with the discharge valves also. The 242 pump is a very reliable pump that gives little problems. Have these pumps ever been rebuilt? If so how long ago. What type oil do you use? I would use a synthetic oil like t30 all season. This will help with carry over and carbon buildup. Are these parts being installed correctly? Use OEM parts. After market often don't include keepers,screws or other hardware.OEM has all the necessary hardware to correctly replace the valves.
