This was mentioned in my TRV4 thread, but wasn't the main subject, so I'm
starting a new thread.

I've already discounted using valves with the drain-off in the tail because
they would likely foul the out-turned seam on some of my rads as they were
screwed in.

Looking at the BES online catalogue, there appear to be at least two types
with outboard drain-offs - the 15mm ones being #7783 and #7508 respectively.
I can see how they differ in appearance, but would someone care to explain
how they differ in *function*? The second one apparently has a drain-off to
BS 2767, Type 10. Anyone know what that means in real money?

BES also do a "Radiator Drain Off Valve" (part# 7509) which doesn't actually
appear to be a radiator valve! Anyone know what that's for?

Re what you said above about the valve fouling your rads ...surely
the part with the drain does not screw in to the rad . It's a seperate
smaller tail part with a nut that screws in to the rad and the main
body of the valve then attaches to it by screwing the previously
mentioned nut to the valve .

Looking at 7509 however that looks as if it DOES screw in to the rad
and looks as if it is just for draining off the contents of the rad so
maybe gets used in a system where the rad has some other piping
arrangment . It appears as if the stub at the bottom connects to a
hose .??

I was referring to valves such as the Pegler Terrier
http://www.screwfix.com/app/sfd/cat/...20865&id=83588
where the drain is integral with the tail and *does* rotate as you screw it
in.

Looks far too poncy that one .:-)

Oi - I've got those ones!

They're OK, but I found them tricky to tighten without damaging the
crome plating slightly.

I use those on drop fed rads. 1, because they are good quality and
rarely weep after years of service. 2 because you can connect a hose
and drain it completely dry. That is, some of the inline drain valves
have a small grub screw with o-ring. You have to use a bleed key to
remove this and deal with water squirting everywhere while you push on
the hose.

BES #7783 and #7508 are cheap and nasty so don´t waste your money.
#7509 is used inline between rad and standard lockshield. You turn the
the bottom assembly rather like a tap to open it. This is obviously
better than the bleed screw variety. It can look a bit out of place as
it moves the lockshield off the rad by about 10 cms.

If you want decent lockshields then use Myson or Pegler. Forget the
valves you can buy for a few quid.

Thanks for your comments. Do either Myson or Pegler do lockshields with the
drain at the end - similar to (but hopefully better than!) the BES valves
which I cited?

Yes Myson do one exactly like that with the drain off at 90 degrees to
the wheelhead. The one with the bleed screw/ o-ring variety. You will
have to go to one of the merchants to get them - I would recommend you
try PTS as they carry a wider range of the Myson lockshield/wheelhead
valves. Don´t be fobbed off with non-branded versions, as they can
order in if they have no stock.
