2-Pack In-Line Barbed Ball Valve 16mm For 1/2 and 5/8 Inch Tubing (.570 to .620 ID) - Regulate and Shut-Off/On Water Flow

I have two large sequoia trees that required 150 feet of drip line with 150 emitters. The trees require monthly watering for 10 hours in summer. However the same circuit also irrigates bushes along the property line requiring every other week watering for two hours. The solution was a set of these valves that will now let me water the trees without wasting 750 gal of water on the bushes!

Great valves, worked perfectly...didn't even need clamps with tubing for leak-free connections. Easily adjustable even for finite water flow adjustments.

I needed this to install on a large drip line in my garden to help control the amount od water one area was getting. The idea worked beautifully. The only drawback is if ai forget to open or close the valve!

Perfect full flow 3/4 valves. Little restriction. Ozone injector still works with this valve.

I bought this valve to install adjacent to a fountain pump. The pump had an internal regulator that failed, so rather than buy a new pump, I added this flow valve. So far it is working really well and has done exactly what I needed.

These function well. Solid on/off turn. Used to split off the drip line from the daily use drip line (normally on) and then allow me to switch to the deep soak weekly drip line for a new planted tree. Works really slick.

These pop off while watering the garden.... then the whole garden is flooded

Had issues with another brand and returned. These worked great.
