Proportional relief valve release the pressure in pipelines by diverting the flow of media as a way to protect the pipeline components. The valves open in proportion as the upstream pressure increases above the set pressure and close gradually as the upstream pressure decreases. Relief valves are proportional relief valves that open gradually as the pressure increases.
- Spring-Loaded Design: The valve opens when the pressure in the system exceeds a preset limit.
- Proportional Flow: The valve offers proportional flow, meaning that as the pressure increases beyond the setpoint, the flow rate through the valve also increases. This helps to maintain a controlled pressure release.
- Materials: The valve is typically constructed from stainless steel for durability and corrosion resistance.
- Applications: Pressure relief valves are used in various industries to protect systems from overpressure, including:
- Oil and gas
- Chemical processing
- Power generation
