My instructor mentioned that the company he used to own and now consults for has switched over to using the Little Valve almost exclusively. It allows you to purchase all 15 foot radius sprays and then trade out the stems and install the Little Valve stems. The Little Valves then allow you to adjust the spray from 15' down to drip and anything in between. This would allow you to eliminate 5' 8' 10' and 12 foot sprays. Do any of you have any experiance with these? Here is the web site.

Pass; that's about as dumb as I've ever heard; no one considered plant growth and the blocking down the road? :hammerhead:

I think FIMCO has used them, but it's probably cheaper and quicker to just inventory a full range of nozzles, rather than having to dismantle a popup body and replace the popup stem with a Valvette.

Besides, you may have occasion to require 2-inch popups with smaller nozzles.

15 foot down to drip... The DU must be superb.

The precip rate goes way up with the little valves (i.e 15' nozzle adjusted to 12' or 10')

Does that imply that output is same, regardless of distance?



MPR's would be worth 12x the value of a "valvette" if this is so.

Their chart shows a 1.99 precip rate for a 15' nozzle adjusted down to 10'.

Not sure of the DU thou.

Just hope that a small rock, or piece of gravel doesn't get into that hole in the stem or the head might not pop up or pop down.
I guess they don't have rocky soil in New Braunfels.

At that quantity, I said thanks, but no thanks.

The concept of throttling down the flow to a nozzle still has merit. I've used PCS screens on Rainbird systems, and they can be the difference between effective and poor performance on systems with marginal water pressures. (Retrofits, for the most, since you don't design from scratch at the margins of performance)

I haven't had any exp with a little valves. But I'm guessing the DU overtime becomes horrible and has many streaks just like the RB Vans

Is a Valvette like a Chevette?
