What is PRV and what are different types

Question

Accepted Answer

PRV stands for Pressure Relief Valve. It is a safety device used to protect equipment and systems from overpressure.

PRVs are used in various industries such as oil and gas, chemical, and power generation.
There are different types of PRVs such as spring-loaded, pilot-operated, and bellows.
Spring-loaded PRVs are the most common type and operate by using a spring to keep the valve closed until the pressure exceeds a set limit.
Pilot-operated PRVs use a smaller valve to control the pressure on the main valve, allowing for more precise pressure control.
Bellows PRVs use a metal bellows to control the valve, making them suitable for high-temperature applications.
PRVs should be regularly inspected and tested to ensure they are functioning properly.
