Weep issue - Solenoid?

[I.B. Washincars]

I wonder what model ASCO valve those who are having the failures are using.

I don't remember the part#, but I bought the exact one you recommended. It seemed like Kleen-Rite's # may have been SA-218.

Yep, here it is.

Brass 2-Way Normally Open Solenoid Valve, 1/2 In Ports, 125 PSI, 24VAC | ASCO | 8210G034

Get a great deal on Asco Red Hat brass solenoid valves, able to handle air, inert gases, and water at up to 125 PSI!

That's the same one Belanger used on the Vector units which wouldn't last more than a couple years. On some of them the brass seat eroded.

What kind of flow rate are we looking at on a Vector unit?

 

[MEP001]

I doubt it's more than 10 GPM. There are three that control the flow of water for presoak, wax, and trifoam, with the chemicals pumped in after them.

So maybe the culprit? 10gpm! Through a 1/2" valve?? I weep 64oz minute for 4 HP Hoses, so very low flow. I feed the valve with a 3/4" poly braid hose to slow water flow even further to minimize or eliminate water hammer when the valve shuts off...So could this be why some are seeing exceptional life out of this valve, and others not so much???

 

[MEP001]

I was thinking manufacturing defect, since any of the three valves would fail on different machines.

 

[2Biz]

My point being, maybe the wrong valve was being used for a specific application causing it to fail prematurely. Too high of flow rate for this valve. How is it the valves fault?

I think you might be mistaken MEP, I had to clean out a couple of my ASCO Weep valves the other day, the city decided to work on the water main and got a lot of plastic debris in the water system. When I opened them up both of the ASCO 8210G34 valves have a stainless steel seat inside. One is over 20 years old and the other is about 8 years old.

It's within the pressure specs of the valve. I've not heard of exceeding flow of a solenoid.

Then they weren't the exact same model, Belanger uses the ones with the brass seat.

You've got a point. Max operating pressure is 150 using water. We literally have 100's of Asco valves in service where I work (Manufacturing) and I've never heard of any issues with them. They run 24-7...365 days a year....

So curiosity got the best of me. Took my spare apart and it has a brass seat. Hmmm...I still stand behind them! I agree with others on the rebuild kit...They sure are proud of them! About as high as a new valve!!
