Dramm brass shut-o? valve is a professional quality full flow valve. Made of brass for durability. Aluminum shut-off valve is identical to brass valve with lighter weight body made of aluminum. Dramm valves are made in the USA.The 1/2 inch opening in this valve will allow 16 US gallons of flow per minute at 60 PSI. This is more flow than a 5/8 inch garden hose can supply, and as much as a 3/4 inch garden hose can supply. This does makes the valve "full flow".
