1/2"
old-skool qev.
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:

I just ordered this
Ordering FAIL!!
lol don't worry we've all been there
"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
Children are the future
unless we stop them now

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

...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.

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.co ... 026e10.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

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