Rugged, single stage station regulator for medium heavy-duty heating and cutting gas pipeline applications
8066691-01-1 shown

The 6690 Series medium heavy-duty welding heating and cutting regulator provides steady and reliable pressure control in industrial gas pipeline applications requiring moderate flow rates. The unique CAPSULE® seat design provides accurate pressure control and extended component lifecycle, while the large orifice seat enables low to medium flow rates. Combined with robust materials of construction and a wide range of delivery pressures, the CONCOA 6690 regulator is the ideal regulator for medium duty welding, heating, and cutting applications.
