Automated Water Valve Options

[Sacedog]

I was speaking with our plumber today, and showed him the Elk WSV that I was planning on having him install. He was very impressed with the unit, but he suggested that I get one with a 1 1/4" opening, rather than the 1" that the WSV is. Well, I know that Elk only sells the 1" version (at least I think I know that), so I either need to find another vendor, or have the plumber neck down the main coming into the house.

Does anyone know of any other manufacturers who make a larger automated water valve?

WaterCop offers a variety of sizes.

I purchased mine from Assured Automation. (Might be where Elk buys theirs )

I couldn't get it to show the one I bought with a link. You will have to select electric, 12v and 1.25" size after you hit the web page.

Why did he suggest going with the larger sized shut off valve? What size supply pipe do you have? I believe the WSV's were non-restricting (eg: a 1" WSV means that there's an entire 1" diameter of open pipe when the valve is open) -- but you may want to verify.

If your supply is 1" and the WSV is 1" (and truly is non-restricting), you'll get no benefit from a larger valve. If you have a larger diameter supply, you should get a shut-off vavle that matches the diamer of your supply line (especially if you live in a community where that's a code requirement!)

The supply is a 1 1/4", so I am guessing that is why. Anyone want a great deal on an Elk WSV?

Interestingly, that looks just like the Elk WSV. So I assume the part number for the 1 1/4", electric, 12v model, would be F26NRXV4F? Will this unit work just like the Elk one (4 leads)?

Also, why did you go with this valve at over twice the cost of a WaterCop valve?

Where did you see the Water Cop for half the price of the "other" valve?

The AA valve is industrial-grade, the watercop isn't. Spanky posted a message a while ago about a "pencil test" (eg: is there enough power to break a normal pencil that he shoved in the valve. Spanky said at the time that these devices are likely to have mineral build-up unless used constantly, and therefore they need a ton of torque.

Most folks here that have a WSV cycle it daily or weekly to help prevent mineral build-up.

As for "What should you do with the WSV you have," if you bought it through AO, you can probably return it. If not, PM me an offer, and I might just take you up on it

What's the difference between the V4 Series and R4 Series valvles?

 

[Sacedog]

Where did you see the Water Cop for half the price of the "other" valve?

Well, not half... $389 vs. $563 for a 1 1/4" valve.

Well, not half... $389 vs. $563 for a 1 1/4" valve.

What does the $389 include? Just the valve, or an entire kit with some wireless sensors?

Just the valve:

Go about 3/4 down the page, and you will see the valves only.

I sent an E-mail to Assured Automation, to get more information about their electrically actuated water valves.

The sales rep said that there was a slight difference in tourque ranges between the R4 and V4. They carry both because in certain sizes the R is cheaper, while in other sizes the V is cheaper. They both operate the same.

He said that they need to be hooked up to a DPDT switch to flip power to the correct terminals, when sending it open vs closed. The Elk WSV is hooked up to a SPDT relay. What's the difference?

 

[Spanky]

1 1/4 inch valves can be special ordered, but they are more expensive.

A DPDT (Double Pole Double Throw) relay actually is like switching TWO SPDT (Single Pole Double Throw) relays at the same time as it has "twice" the poles.
