Review:

This is a very basic valve meant for projects where low price is the major concern. This valve is used for a lot of tract home irrigation systems. The body is PVC, so keep it out of sunlight. The flow control is optional, I strongly suggest that you select a valve that has a flow control. Without it you can't fine tune the irrigation system performance and at low flows you may experience problems with valves not closing very fast or at all. I don't particularly like the flow control handle on this valve, it is difficult to reach and is small. You may need a big screwdriver to turn it.

Manufacturer's Performance Data:

Valve Pressure Loss for 1" SRV Valves
Flow 1 5 10 15 20 25 30
PSI Loss 1.1 1.9 1.9 1.6* 3.3 5.0 6.1

* It's not an error. Weird pressure variations like this at different flow rates are typical of valves. They are caused by water turbulence within the valve.

I don't recommend operating valves at flow rates that result in higher than 5.0 PSI loss. You need to have a really good understanding of hydraulics and water hammer at these higher flow rates. While the valve can handle that flow, the pipes on either side may not!
