The primary function of a relief valve is to protect equipment and piping systems from excessive pressure. When pressure builds up beyond a safe threshold, the valve automatically opens to release the excess pressure. This process not only protects the equipment from damage but also minimizes the risk of explosions or other hazards associated with over-pressurization. Once the pressure returns to a safe level, the valve closes, ensuring that the system continues to function effectively.

When a pressure increase is detected, the relief valve opens to vent the accumulated pressure, thereby allowing the system to return to a safe operating level. The operation of a relief valve is governed by the principles of physics; when pressure builds to a level that exceeds the spring force holding the valve closed, the valve opens. For spring-loaded relief valves, the system pressure pushes against the valve seat, lifting it open and allowing the excess pressure to escape.

In addition to regulating the pressure of the gas, gas PRSs also play a role in filtering and conditioning the gas. Filters are used to remove impurities, such as dirt, moisture, and debris, from the gas before it is distributed. This helps to prevent damage to pipelines and equipment, as well as ensure the quality of the gas being delivered. Conditioning equipment, such as heaters and coolers, may also be used to adjust the temperature of the gas to meet specific requirements.
