What is the difference between a pressure relief valve and a back pressure regulator? In this blog, Fluid Controls will outline the key features and benefits of each to help with your buying decisions.
A pressure relief valve is a safety feature that automatically opens when the pressure of the system gets too high. The valve opens, giving the pressure a release point, then closes when the levels return back to normal. It is the last safety mechanism to prevent any accidents or explosions in extremely high-pressure environments.
A back pressure regulator is a device used to accurately control the pressure of a system, through opening just as much as is needed to return to normal pressure levels. The back pressure regulator keeps a steady pressure flow and reacts to the levels of the system to keep good stability. We have a selection of back pressure regulators including spring loaded, dome loaded and piston style regulators from a range of suppliers.
The main similarity between both is that their function is to control the level of pressure. The difference is how. The pressure relief valve is simply a safety mechanism that automatically opens or closes depending on the pressure and if it needs a release. The back pressure regulator however, is a continually moving application that has pressure sensors that react accordingly. It isn’t just a safety device, it’s a functioning part of the system.
