Heater control valve

Is there a way to resurrect / repair a leaking heater control valve for a series V?
Anyone have any success in rebuilding one?

I have seen the Alpine Innovations replacement.

thanks all

Why do anything other than fit the Alpine Innovations upgrade? It is a much better design, simple to fit and if it ever fails in the future it can be easily repaired. We have no connection with AI but find their products to be first class, well designed and competitively priced.

I am a tinkerer at heart. I see a mechanical problem in my hobby car and I enjoy the play. Not having a functional heater where I live is not a big deal. There are times I would rather wrench than drive.

I just came across this valve on eBay, completely by accident. The copy says the inlet and outlet are 16mm, which is just a hair larger than 5/8". I am not quite sure how I'd mount it, but for $15 delivered, it might be worth trying.

565FDF75-3A2C-4169-B630-2D0CEBAC7827.jpeg Have one of those on my Singer. Not really mounted to anything, just inline on the hose. Cable attaches to knob inside the car to open and close the valve for water flow.

Thanks. That looks like it would work just fine. My current one (NOS, installed probably 10+ years ago) works just fine, but for $15 I think I will pick up one of them just to have around.

I didn’t attempt to connect to the stock heater slider. I ran a new cable and casing from the water control valve through to the dash and mounted the knob end in a non conspicuous location on the lower dash.

I think the biggest challenge is getting the internal rubber parts for the stock valve. I inquired about that to a reseller of the valves and he didn't know either. I repaired a blown off end on mine, but the internals were not that old, so were ok to reuse. I'd attempt to fix others I have laying around here with bad internals by pulling off the end and reassembling with the modified end I came up with. Any valve I think would eventually fail due to internal rubber parts aging, so having them serviceable seems like a good idea any way. I do realize many of these have other failure issues not related to the internal components.

What I did after the end cap blew off was to grind the tabs off because I think that is a weak spot. Then I filed some grooves in the valve body for skinny bolts and implemented a series of three grooved washers to both sandwich the rubber end seal and grab the end of the valve. Looks pretty close to original if that is the goal.
