6590 Series Flowmeter Regulator

Rugged flowmeter regulator for medium heavy-duty heating and cutting applications
8066574-01-1 shown

The 6590 Series medium heavy-duty heating and cutting regulator provides steady and reliable flow control in point-of-use applications such as MIG and TIG shielding gas control. The encapsulated seat design provides accurate flow control and an extended component lifecycle. The optional gas-saver model keeps a constant level of gas pressure in the downstream system during the welding process. This prevents pressure and flow surges that can create gas waste and cause a poor weld. The CONCOA 6590 Series flowmeter regulator offers a wide range of delivery flows, making it an ideal choice for point-of-use applications.
