Any compressed air pressure vessel must be protected from an over-pressure situation - the maximum allowable working pressure (MAWP) approved by DOSH must not be exceeded. A pressure relief valve is used to limit the pressure build-up in a system, by automatically relieved by a spring-loaded valve, actuated by the static pressure upstream of the device. The valve opens in proportion to the increase in pressure over the opening pressure.
