Pressure Relief Valve (PRV)
A pressure relief valve (PRV) is super important for safety. It helps control or release excess pressure in a system. These valves are used in many industries, such as chemicals, power, and oil and gas. They ensure equipment runs safely and prevent disasters.
In simple words, a pressure relief valve protects a pressurised system from getting too much pressure, which could be dangerous. So, if pressure gets too high, the valve kicks in to keep things safe.
Types of pressure relief valves
Relief Valve
These are slow and steady helpers for dealing with pressure. They work with fluids that don't squeeze down much, like water. There are two kinds: adjustable ones that you can tweak and electronic ones that use electricity to control pressure precisely. They're good for systems where the pressure needs to stay pretty stable.
Safety Valve
These are the quick responders. They're used when dealing with gases and vapours that can quickly build up pressure, like in steam boilers. They come in three types: low-lift, which handles small amounts of pressure; high-lift, which deals with a bit more; and full-lift, which is for heavy-duty situations, like big steam systems.
Safety Relief Valve
These are like flexible friends. They can handle liquids and gases, and they can open slowly or quickly, depending on what's needed. So, they're versatile and can adapt to different situations.
