TESCOM™ DH Series Single Stage Regulator

Tescom

DH-Series single-stage regulator provides a compact size with high flow capability from 5-200 SCFM / 142-5663 SLPM. The large diaphragm and balanced main valve design provide low 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. DHF Series high flow pressure reducing regulators come with flanges according to EN 1092 and are suitable for gas service. Ideal for use in high flow facility gas supply.
