The G2 Linear Flow Valve allows you to easily fine tune your flow rate for sparging, lautering and chilling, increasing the repeatability of your system. The built in 90 degree outlet can be oriented at any angle to make hose routing simple and kink-free. Eliminate those extra elbows and other fittings on the valve for clean and simple routing. Unlike other valves, the new G2 valve disassembles in seconds for a quick cleaning! The cool-touch silicone grip makes handling under fire easy, and the silicone material handles temps to 600 F so it won't melt like vinyl grips on ball valves do. The G2 linear flow valve is one of the many features tailored specifically for homebrewers.

Ball valves are an economical and durable choice for on/off applications. But they are not ideal for flow control. A globe valve, like the new G2 linear flow valve, is ideal for applications where flow control is needed in addition to on/off operation. We have added a parabolic shape to the valve stem to make the flow characteristics nearly linear.

The G2 valve has a direct relationship between flow and position of the valve (a straight line). Specifically, when the valve is 1/4th (25%) open the flow is 1/4th (25%) of the maximum flow rate. At 1/2 open (50%) it is at half the max flow rate and so on. Therefore feathering the flow for sparging, lautering etc. is very intuitive and easy to control. The ball valve (the red line), on the other hand, has a flow that is not directly proportional to the position of the handle. When the valve is opened 1/4th of the way (25%), it puts out about 1/2 (50%) of its total flow. At half open (50%), it puts out about 3/4 (75%) of its full flow. This makes trimming the flow a little tricky.

5 of 5 G2 Linear Flow Valve March 20, 2015
Reviewer: Dave from Ontario  
Installed very easily, but note that Blichmann tapped the threads deep and wide, so you may need more teflon tape than regular fittings.  Because of this, you should end up with almost no threads remaining in the fluid contact areas, which is a huge bonus.  Comes with a silicone O-ring for pot surface flush mount install if you choose that route, but can be installed onto fittings not as flush mount, etc... Cleaning only takes a few seconds; remove the valve stem by fully opening the valve, then flush and/or brush.

As the info seems to be lacking on the above description, yes this is ½” NPT, both ends.

Can be used on Tallboy kettles and pretty much any other pot on which you use ½” NPT fittings. On my 10 gallon Tallboy, the valve outlet pointing down is about a millimeter higher than the bottom of the pot.  Not a problem for me as the valve will always be overhanging beyond the burner or a counter.
