Safety Valve (PRV) versus. Relief Valve (PSV): What is the Difference

That stated, relief valves and safety valves do function slightly differently: Relief Valves are made to control pressure inside a system, most frequently in fluid or compressed air systems. These valves open compared to the rise in system pressure. What this means is it normally won't fly completely open once the product is slightly overpressure.
