In the second part of a four-part series on pressure regulators, Keith Hall explores the basics around controlling pressure in cryogenic tanks, with pressure reducing/building regulators
There’s a strange conundrum at the heart of this feature on pressure control, and it is this. The regulator that does the work goes by two opposite-sounding names – a pressure building regulator or a pressure reducing regulator. Confused? Just read on.
Pressure reducing regulators are used to control downstream or outlet pressure in a piping circuit or system. One familiar application, for example, is the use of a pressure reducing regulator to restrict 100 psi shop air to 50 psi when supplying air to a paint gun.
