Heater Control Valve Repair

I started on making a new valve last week, and I got it together this afternoon. I used SolidWorks to help me visualize the parts to make. Using O-rings is the way to go. The housing is made from brass tubing & brass bar and silver-soldered together.
(Please don't ask me to sell one, I don't have the time right now)

Well done! Looks pretty easy to make with a decent lathe. Will you be sharing the CAD files or a measured drawing?

Nice work. I understand the amount of work it would require to produce these would make it hard to sell at a reasonable price for the small market it would fill. Nice that you have the skills to make the one you need.

I just don't have the time to give details or make & sell them right now, if at all. Sorry, too many things going on. This was a priority to get the Tiger running again.

Nice !
There are at least two issues with these valves.. they separate at the side tube fitting or the end with the plunger pops off. Further, they are not practically internally serviceable due to the plunger end mounting method. Jan's solution appears to address both. I also fabricated a revised plunger end to address my pop off issue and in turn, and in theory, provided for serviceable internals. I ground off the four cast tabs holding the end plate on, then altered three washers to accept small screws with nuts. Alas, I've not been able to obtain original internal parts. For now, it works. May have to adopt Jan's internal scheme at some point.

Yes, a couple of problems using the original aluminum housing is: 1) the rear flange (not large enough in diameter for even 2-56 screw holes) and 2) the internal bore is tapered (this is normal for die-cast aluminum parts). That tapered bore needs to be bored (to use in my solution) and as well as a clean-up of the corrosion pitting. So I decided not to go down that path, and make a new housing from brass metal.
