My safety valve keeps popping off well below the psi max operating level.
by Joe Mistretta
So I have a 5 gal. pancake compressor Central Pneumatic that is a 150 psi max compressor. I'm using it to fill a pressure pot for pressure casting molds. The pressure pot is also a Central Pneumatic rated for max working psi of 60. The pancake output gauge is set to 50 psi. The pressure pot's safety valve keeps popping off at or below 40 psi. I need it to stay at 40-55 psi for proper pressure molding and pressure casting. Why is the safety valve popping too soon and how can I fix it? An I adjusting something wrong or doing something wrong? Sorry I don't have photos.
