Safety relief valves are automatic devices set to open at a predetermined pressure to relieve excess pressure from a system. The primary function of an SRV is to protect the equipment from the consequences of overpressure conditions that can occur during normal operation or due to unforeseen failures. These valves can be found in pressure vessels, boilers, and piping systems, where they serve to prevent catastrophic failures that could result in explosions or leaks.

The fundamental working principle of a pressure reducer is relatively straightforward. It consists of an inlet and an outlet, along with an adjustable spring mechanism. When high-pressure gas enters the reducer, it pushes against a diaphragm connected to the spring. The diaphragm moves, adjusting the size of the outlet opening, which controls the flow of gas exiting the reducer. If the output pressure rises above a set limit, the diaphragm moves to decrease the opening size, thus reducing the flow and maintaining a stable pressure.
