Hi Ian, looking at your prototype and it's components it appears to follow the same fundamental design of the LR one, albeit with far superior components, machining and assembly. So I’m assuming you have concluded that the original design is good, however it’s implementation is poor. Is this the case or have you spotted a flaw in the original design and corrected it ?

Ps. I suspect that the round sealing rings are a challenge to get right and perform well over a long period of time.

Fully understand if you can’t provide too many details, as it’s your your intellectual property and likely commercially sensitive, but anything you are happy to share would be appreciated.

Noting I’m very interested in purchasing one ( at a reasonable price

) if it has corrected the flaws in the original heater valve.

These images are on the design and development facebook page.

Looks like a very high quality version of the origional.

Truly a thing of beauty. I can’t wait for them to be ready. WARNING.

Thanks for posting the pics Mata, those are the ones I looked at a few months ago and it’s really useful having them posted here

Three issues seem to plague the original valve.

1. It can start to leak at the main body seam.
2. In some instances the Bowden cable does not fully push the valve leaver back, allowing hot coolant to continue to flow to the heater matrix even when set to fully cold by the heater control knob.
3. In some instances even with the valve leaver fully pushed back and the heater control knob on fully cold the valve internals still let hot coolant flow to the heater matrix.

I Agee with Zed, it does look a thing of beauty, as does everything I’ve seen from Design and development engineering, and IRB’s bespoke components such as their output shaft. ( I’m likely to purchase and fit an IRB output shaft soon)

Hence I’m keen on IRB ( ian, Porny on here) providing as much insight as he feels appropriate on how the 3 points I highlighted above ( perhaps more I’m unaware of ) are addressed by his collaboration with D&DE on this solution.
