Yes, you can but there really is no advantage. Most folks start with both caps off and the valve wide open. As the temp rises, one cap goes on - then the other cap goes on, then the valve is gradually closed to reach the desired temp. Only one inlet is adjudted so only one valve is required (cheaper that way).
If you have 3 drums then buy 3 valves, put them all on one drum and see how you like it. You will then have the option of removing two of the valves and putting them on your other drums, Whats to lose??
