Relief Valve Vs Reducing Valve
| Relief Valves | Reducing Valves |
| Relief Valves: Also known as the overflow valve | It is referred to as a pressure regulator. |
| It is a type of safety Valves used to control or limit the pressure in a system | Reducing valves control their outlet or downstream pressure only. |
| It is Used in oil and gas, petrochemical, and power generation using steam, air, gas or liquid. | It is used to maintain constant reduced pressure in a pipeline where the flow is fluctuating. |
Boiler Pressure Relief Valve Function
A relief Valves or pressure relief Valves (PRV) is a type of safety Valves used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire.
Thermal Relief Valve Advantages
