They are all pressure relief valves that are design to open when there is an over pressure in the fluid line. This overpressure is usually 10-15% of the intended pressure in the line. As said be Neil, they are set by springs and sometimes can be set by

The only difference is the pressure relief valve acts as a safety feature to release pressure buildup. Conversely, the back pressure regulator is a part of the system to maintain a predetermined pressure. Norgas Controls provides gas regulators, gas valves, and gas meters for natural, propane, compressed, and sour gases across Canada.

Like pressure regulators, there exist multiple styles of pressure-reducing valves. Notably, the pressure relief valve serves to enhance the safety of a system by enacting failsafes and control. The relief valve serves as an escape route for pressure build-up once a set pressure is exceeded to prevent damage to equipment and operators.

Relief valve In fact, the relief valve is divided into two types of direct-acting type and pilot type. The direct-acting structure is simple, the manufacturing accuracy is not high, and the cost is low. Low resistance and sensitive movements. The disadvantage is that the pressure lag is relatively serious, and it is easy to produce vibration.
