Supply pressure effect in regulators

Supply Pressure Effect in Regulators

Supply Pressure Effect, or Dependency, is stated as a ratio describing the change in outlet pressure for every 100 psi change in inlet pressure. As outlet pressure rises the supply pressure decreases, and the opposite can be true as supply pressure increases. The most common example would be when a gas supply cylinder or tank is used. The supply pressure of the fluid begins to decrease while the cylinder empties. This situation will increase the downstream delivery pressure. A second example may be on start up or shutdown, where a regulator may be set to the off position before turning the supply pressure on or off to prevent overpressurization of the regulator diaphragm, outlet pressure gauges or downstream equipment.
