High-Accuracy Regulators


To meet the demands of a changing industry, the new DR-2 Series miniature regulator design packs greater accuracy and repeatability and the same optimal flow and performance characteristics as the MAR regulator in a sleek, durable package.


The new system is available in either relieving or non-relieving versions. The relieving design maintains a constant pressure output even when downstream conditions change, and can accommodate compatible water, oil, or air applications. The non-relieving option, for air applications, is built with no vent to the atmosphere, and so does not compensate for changes in downstream flow or pressure.


The DR-2 Series boasts repeatability of ±0.15 psi and features  electroless nickel-plated brass bodies, FKM seals, and stainless steel adjustment screws and springs.
