Differential Pressure Regulators function like a back pressure regulator but sense an auxiliary pressure source in addition to upstream pressure. The differential is maintained in accordance with the adjustment screw setpoint, so flow is consistent and metered appropriately.
Common applications include use in meter runs and gas injection in gas lift applications to help control flow.
The regulator is designed to control a set difference between upstream pressure and downstream OR auxiliary pressure from a downstream process/vessel. The differential (upstream pressure – downstream/auxiliary pressure) must be greater than the bonnet spring force to allow for the regulator to open. When at setpoint, any downstream/auxiliary pressure increases will require a corresponding increase in upstream pressure to allow for the same positioning of the inner valve.

No, typical applications for these regulators only deal with metering gas flow based on differential pressure from two different gas sources
Repair Kits are available for all regulators. Maintenance is recommended to be performed at least once a year. However, this frequency can increase depending on the application and potential changes in operation conditions.
