- http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... SA:GB:1123

1/2" old-skool qev. :D
There are still a couple left if anybody here is interested.

The brass finish and the shape attracted me.
I'm guessing it uses a diaphragm like a rainbird valve or something. What sort of pressures would you trust it at?
Has anyone here used anything similar before?...What was it like?
I'm curious...

Good find! I just enquired about postage to epoxyland :)

The construction does suggest it uses a diaphragm.

Just noticed this -

"This item requires Enots nuts and sleeves for all three ports on this valve. "

Is anyone here familiar with Enots threads etc.? I've never heard of them before. I'm just hoping I'll be able to buy BSP/metric adapters for it. :confused1:

Ordering FAIL!!
lol don't worry we've all been there :oops:

"This item requires Enots nuts and sleeves for all three ports on this valve. "
Naah wait... I did a quick google search and it seems that enot nuts and sleeves are just compression fittings

http://www.airlink-compressors.co.uk/pr ... t-imperial

So I guess it has standard 1/2" BSP threads

Aaah...All is good then. I was wondering where I was going to get these mysterious fittings from. :D

...Cheap, even with the p+p!
What are you going to do with yours? I'll have to think about it as they're an interesting but strange shape.

guess fail :lol:

yes they're industrial copmpession fittings, unlike normal compression fittings the compression nut has a male thread. the 1/2" refers to the OD of the pipe to be used, here's a datasheet:

http://docs-europe.electrocomponents.com/webdocs/0026/0900766b80026e10.pdf
look on page 6, the thread for a 1/2" fitting is 3/4 x 24TPI Which is a lot finer than a bsp thread.
still i'm sure you can bodge somerthing together with brute force and plenty of epoxy :D

Aaaaaah........ :roll:

I'll probably have to send off for some fittings when/if the time comes - I'm not very good at bodging.

Update: arrived this morning, yes it's a diaphragm valve and yes the threads are bigger than 1/2" BSP, almost big enough to fit 3/4" BSP.

No problem for yours truly and his binary adhesive stockpile of course, will have a play after Monday when the other half finally heads back to the motherland :roll:

I'm thinking of using one of these as a pilot to make a small calibre semi-auto...
