6790 Series Pipeline Regulator

High-flow, single stage regulator for heavy-duty industrial gas pipeline applications
8066791-01-1 shown

The 6790 Series high flow, heavy-duty, rugged heating and cutting regulator provides steady and reliable pressure control in industrial gas pipeline applications requiring high flow rates. The balanced stem seat design mitigates fluctuations in outlet pressure caused by variable inlet pressures, while the large orifice seat and 1/2-inch ports provide high flow capacity. Combined with robust materials of construction and a wide range of delivery pressures, the 6790 Series regulator is ideal for rugged heating and cutting applications.
