Difference between pressure relief valves and self-acting pressure regulators
Under normal circumstances, self-acting control valves use the medium within the pipeline as the power source to regulate themselves based on a pre-set pressure. A pressure relief valve is a valve that reduces pressure to a certain level by manually adjusting its internal components. Relatively speaking, self-acting pressure regulators should be more stable in response to fluctuations in medium pressure.
Pressure relief valves are generally used to reduce high pressure to low pressure. Automatic control valves require parameters to be set before use, and the pressure must remain within the specified range; if the pressure is too low, it can be increased slightly, and if it is too high, it can be decreased slightly
