This second cable on Nick's valve is puzzling me. I can't think why it would be required, because there's only one valve. I can only guess that they didn't use the same solid cables on the 407. The point being that the solid core control cable is able to push the valve actuator as well as pull it.
Nick, are you absolutely sure that lower cable is connected to the valve? I have attached some detailed photos of a valve from an Aston. I suspect the internals are interchangeable. From memory I think the original one which came off my DB6 had a separate diaphragm spring, but if you take yours apart you should be able to see whether the diaphragm with the retained spring will work as a replacement in your valve body. You might be able to buy that diaphragm separately, but even if you can't do that, you can buy the Spitfire/GT6 valve for circa £20 and just use the parts. Let us know how you get on. Kevin

Thank you all for your help, it just shows how wonderful these Forums are.
ACCS Martin Barns emailed me to say he had a new one in stock! It is the correct one with two cables and a rod. One cable is the heater control and the other is demist. Whilst he was on he informed me he stock all glass including 411 heated rear screens, all suspension,gearbox,axles etc.. Why I did not ask him is that I thought he only did the yank parts. Anyway well done Martin. contact 020-72789786 or brisparts@aol.com Thank you for your help, ideas and warnings. Nick

407 heater valve
£36.00 plus VAT, but at least I know it is the right one.
When I asked a Triumph specialist he said that his only had one cable to it. So I left it, he was asking £28.00 I thought better safe than sorry, after all Martin supplies them to Bristol cars, he also supplies them with glass he says! Thank again fot all your help. Nick

Nick, can you take a nice close up photo (or 2) of your valve before you fit to the car and post them here (or send them to me) and we shall see if we can identify it. It could of course be unique to the Bristol 407. Kevin PS. large photos.

407 heater valve
Hi Kevin,
* I did try that route as I pointed out in my first mailing, the Ebay one that is but the trouble was the demist controls. I have not yet received the part but when I do*I will take part numbers and photograph, a bigger size as a luddite, what is the next size 640x640 ? * It should fit a 408 and at a guess a 409. * Nick * * Nick Challacombe.

407 heater valve, eBay
Hi Richard, Not completely certain but UK eBay item 290326979175 for
a Sunbeam Alpine looks pretty close. I'm looking at the fitting to the heater matrix, which is the O-ring type with flange, position of control cable and the other water connection. The Sunbeam one (and all others advertised) do however have a pressed steel cover on the control cable side rather than the original die cast version, maybe when sprayed black it will look OK. Otherwise I might try and fix the original die cast cover to the new valve as that part of mine is OK, it's the other side that has corroded away. Confirmation later when my sister in UK procures it and ships it to NZ... Further to earlier posts regarding the limiting straps on the rear axle of the 405 and other 2 litres.... I used some similar width tie down strapping rated at 1 ton, cut to length, after a few trips in the NZ mud I'm sure they will look fairly original... Stuart
