Compatible with non-copper applications, the -FG series can also be used in environments where flushing with water could damage standard flow controllers, such as in packaging applications or the food industry. This series has been designed to offer maximum control by increasing the number of turns of the adjusting screw up to 10. The body and adjuster are made of highly impact-resistant white resin for a clean appearance. This series also includes SMC's instant fittings, which are available for external tube diameters ranging from 4 to 12 mm.
