G2 Linear Flow Valve

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.

The graph above explains why the flow of the G2 linear flow valve is easier to adjust than a ball valve. 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.

What does this mean and why is this ideal in this application? Looking at the blue line of the graph below, 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.

This is perfect for what I needed in my brew set up - no more burned electric elements! Super easy to clean and sanitize, this was a fantastic addition to my brewhouse.

Randy C
The best ever

If you need to control this is the valve! I use 2 of them and they are great.

Terry Metcalf
Fermenter drain valve

I use this for my fermenter; a converted quarter barrel keg with a triclamp outlet. I have a triclamp flange with a hole just big enough for the valve to fit through. I use this with the dip tube assembly and it reaches to near the bottom of the keg to leave the yeast and trub behind, without having to tip the fermenter! Easy to clean and sanitize.

Jordan Parrott
Great replacement for ball valve

It is great using this instead of a ball valve on my brew kettle. I've read many stories about people finding mold in their ball valve and this gives you piece of mind because you can clean it very easily after every brew.
