Control Devices CR Series Brass Pressure Relief Valve, 0-100 psi Adjustable Pressure Range, 1/4&#034

This is an adjustable pressure relief valve. It is marked 10-100 (PSI). In my case it regulates down to about 8 PSI. The higher end markings on the device seem pretty close to my gauge, but a bit off on the low end. In reality, you need a pressure gauge to be sure of the pressure it is set to if you need accuracy.

This type of regulator works by venting air from the pressure side to the atmosphere when the air pressure on the pressure side is higher than the setting of the regulator.

For what it is it works fine and I am happy with it for my application.

This type of regulator would normally be used for a relatvely small air pump or compressor of 1/2 HP or less such as used for air brush work or even as an auto tire inflator where the compressor runs continuously when in use. Large tank type compressors use a different approach they use an electrical pressure sensing switch to cycle the motor and a series type pressure regulator for the air output on the output from the tank. The two types are not compatible with each other.

Seems to be of fine quality. Have not undergone pressure yet. Pretty nice for price. Exactly what I expected. Gooood.
