Comments: I wanted to use these to dial in automatic dosing. The valve is sticky enough that making very fine adjustments is impossible. It took WAY longer that it should have. However, they are a quality-built item and would work well for less exact purposes.

Comments: Cheap, easy and to the point. used these to replace old valves on a calcium reactor. They work pretty well, but the adjustments are a little clunky. if you are looking for a specific drip count these will work but its pretty tough to make a difference between 2 drips a minute and ten. Nice cheap valves and good barbs for low pressure applications. For more high pressure use brass from a plumbing supply.

Good valve for water flow too

Comments: I bought these for controlling drip rate in a Nitrate Reactor. They have 2 O-Rings inside providing a positive seal plus allowing it to be rotated smoothly. They worked well. The barbed ends gave a good and strong seal to soft airlines and the harder plastic tubing with .170" ID at Home Depot for drip irrigation. I was using that to build the Nitrate Reactor and this valve worked great with it. It is very inexpensive compared to the JG fitted valves. My only complaint is that the valve is free to rotate 360. So, you have to physically see or feel the pointer on the dial to know whether you are in the closed or open position. I have tried using the Lee's airline needle valves and they leak water.
