Air Compressor Relief Valve Testing

Just in time for fall. The original method for regulating compressors was to use a pressure relief valve to release excess air pressure into the atmosphere. This video shows how you can test a safety relief valve on a metrus valve test bench with air or nitrogen.

Usually parts of the valve are made from material such as bronze or brass which greatly reduces the chances of mating parts sticking together due to corrosion or dirt and dust build up.

Air compressor relief valve testing. Hi as a test i ran the compressor up and once it cut out unplugged the hose that runs from the one way value to the unloaderpressure switch at the unloader valve end expecting only a short burst of air from the cylinder and no more as the one way valve would prevent this. Explosions have caused far too much damage in companies over the years and though pressurized tanks and vessels are equipped with best practices for testing pressure relief valves.

When you work with anything that maintains pressure you need to make sure that safety comes first. Pressure relief valves for air compressor systems are simple spring loaded mechanisms. Safety is of the utmost importance when dealing with pressure relief valves. An air compressor is a great tool that can be put to use for many tools such as a spray gun or a water sprayer.

A prv is needed in any system including compressed air where there is the potential for pressure to increase to an unsafe level in a pressure vessel. When the inlet pressure force is greater than the spring load the safety valve opens in proportion to the increase in pressure and allows air to leak out as needed. The valve is designed to limit system pressure and it is critical that they remain in working order to prevent an explosion. The inability to find a new relief valve for this compressor is still frustrating but i guess that will have to be a frustration for another day.

The term pressure relief valve or prv is self explanatory in a general sense. The safety measure on an air compressor is a release valve also known as a relief valve. The set pressure of the relief valve must never exceed the design pressure of the air receiver. Frequently a servo valve controlled by a regulator is used instead.

Pressure systems may have a number of prvs installed to provide redundancy in safety measure. The ac works good pressuresperformance and the relief valve evidently did reseat. So i replaced the expansion valve and got everything vacuumed and charged and now all is good.
