Screwfix do one with the drain at the end, which appears to maintain
the
pipe position

Do you know whether this does the same job? [It's not clear from the
picture
whether the drain connects to the tail, or only to the external
pipe].

It does one of the jobs, which is to provide a drain for the system
as
a whole, or the ground floor radiators to be more precise.

However, the drain may be on the pipe side of the valve and if so
won't allow individual radiator drain down which the Pegler one
will.
Of course that function can be done by undoing the unions but can be
messy and harder to control.

It's hard to say though. Even though the drain cock is opposite
the
tail, it could still be radiator side if the valve seat is in the
bottom near the compression fitting.



B&Q sell identical-looking valves to this and they do drain the
radiators, which is why I fitted them last time I had the system
drained.
