DG Series single-stage regulator provides a compact size with high flow capability greater than 1000 SCFM / 28,300 SLPM. The large diaphragm and balanced main valve design provide lower droop (larger usable flow range) than competitive designs. Available in spring or dome loaded configurations. Ideal for use in purging, blanketing, high flow inerting, heat-treating and shielding gases and performs well at very low pressure differentials such as Dewar-supplied processes. Suitable for multi-drop breathing air stations
