02
Dial flow regulators
-
are single-stage regulators with selectable preset flow rates, adjusted via a top-mounted dial mechanism. These are primarily used where repeatable calibration flow is required with the flexibility to switch between multiple flow rates.
Based on , these regulators are designed for both reactive and non-reactive gases, with multiple material and pressure configurations.
