Source For 3-Way Watermaker Routing Valves ?

Ok, even Google has failed me, or I failed in phrasing my queries.

I've sent an e-mail to Katadyn too, asking them, but have not heard back.

I'm looking for what Katadyn refers to as the "high-quality plastic 3-way valves" used to direct intake and product water. The picture below is from their installation diagram.

I need to get a few more to route more intake and product output options and searching on line has just led me to a bunch of huge or hugely expensive valves of all sorts.

Any ideas ? Thanks.

The only place I was able to find them was from the distributor that I got my watermaker from.

I used a brass valve designed to select fuel tanks--worked fine.

Brass 3 Way Fuel Selector Valve

These might do it !

Thanks for the answers.

Finally went to Amazon and found these:

Ball Valve, 1 Pc, 1/4 In, PVC, Hose Barb - Amazon.com

At least that is a solution !

Same here. I used Apollo 3/8" 3 way valves purchased at a hardware store.
They're working fine after 13 years.

The ones used by all the WM manufacturers are made by SMC. Grainger sells them: SMC CORP. OF AMERICA/SMC PVC Ball Valve,3-Way,FNPT x FNPT,1/4 In - Ball Valves - 3CGZ9|2362890 - Grainger Industrial Supply . Maybe less expensive elsewhere if you google.

Re: Source for 3-way watermaker routing valves ?

The brass ones are great, I've only had larger plastic ones but they became very hard to turn.

swedgelok makes fine valves used in process applications with high pressure and can be stacked if desired . Originally used for instrumentation. Google swedgelok sn you should find what you want.

Re: Source for 3-way watermaker routing valves ?

CAUTION...CAUTION....CAUTION....

You NEVER want to block the output of your water maker product water when the unit is running. You need to use a Non-blocking or transitioning 3-way valve or you run the risk of blowing apart your low pressure plumbing if you block the product water. You can also damage your membrane by causing abrupt pressure fluxuations when turning the valve. Or I have seen the valve inadvertantly bumbed in the middle "off" position and POP goes the low pressure line and things around there get wet....hopefully not expensive electronics.

If you can't find a non-blocking 3-way that will not block the product water flow when turning positions, then as a water maker manufacturer, I would recommed you use two on/off valves and a T fitting. Always OPEN them both and then close the one you want to shut off.

If you blow your low pressure plumbing or damage your membrane by using the improper 3-way non-blocking valve...well you don't want to risk that.

The valve Mark listed on grainger:
SMC CORP. OF AMERICA/SMC PVC Ball Valve,3-Way,FNPT x FNPT,1/4 In - Ball Valves - 3CGZ9|2362890 - Grainger Industrial Supply
Is a great valve and also comes in a nice clean panel mount option and is used by us and sheesh...I think most of the water maker companies for their inlet water selection...but using the non-blocking 3-way on the product water outlet plumbing is a No-no.

Found some !

I got two nice replies from Katadyn, offering to sell me some of their valves, and a suggestion that I look at McMaster.

Of course, why didn't I think of that

Found them at McMaster and just placed the order.

Thanks for all the suggestions here and thanks to Katadyn for the helpful customer service !
