Back Pressure Regulators work differently than standard, or pressure reducing regulators,
and it is important to know the difference.
Pressure reducing regulators reduce a higher supply pressure at
the inlet down to a regulated lower pressure at the outlet (downstream).
Back Pressure Regulators work the opposite way. They regulate the higher
inlet (upstream) pressure by opening up only as much as necessary to hold
back the desired pressure at the inlet (upstream).
Back Pressure Regulators work just like relief valves, but the emphasis is on steady
state pressure control instead of on/off pressure protection.
Back pressure regulators are also similar to back pressure valves,
though the term "valve" implies a different control mechanism.
