Clippard DR-2 Precision Adjustable Pressure Regulators

When Clippard invented miniature pressure regulators in 1962, the MAR Series became very popular as a simple, robust, and cost-effective regulator in a small package with exceptionally long life. As precision regulator applications continue to increase, Clippard is meeting the demand with the newest addition to the reputable regulator line. The new DR-2 Series provides greater accuracy and repeatability while maintaining the same flow and performance characteristics as the MAR regulators in a durable, sleek package.

*Non-relieving models only

These precision pressure controls are offered in either relieving or non-relieving versions. The relieving design maintains a constant pressure output even when downstream conditions change, while non-relieving regulators do not automatically compensate for changes in downstream flow or pressure. There is no vent to atmosphere, as in a relieving type regulator, and the output pressure can increase due to a downstream event. Non-relieving versions can accommodate compatible liquid applications.

The DR-2 regulator's performance may vary in applications where dead end, no flow is required.
