 More-or-less.

 It's an, uh, 'interesting' part. Usually, you'd expect a ball valve
in this type of application but, instead of a ball the valve is
cone-shaped, with a hole for water passage. The cone is held within
the (tapered) body by a spring, with a thin washer on one side and a
thick one, notched to limit the 90deg movement, on the other. Because
it's a cone, the valve requires the spring to hold it tight against
the body, but if they part the valve will leak. I found this out
recently when my heater control valve started to leak and I thought
"No problem, I'll just close the block valve." Then, I took a drive
and the block valve started leaking so badly I needed a tow home. I
hadn't 'exercised' this valve in a long time and I think finally
getting it to move opened a gap between the cone and the body of the
valve (the spring is supposed to hold them tightly together). I took
it apart, cleaned it, and put a slightly thicker flat washer on the
spring.

 Moral of the story: 'Work' this valve occasionally (maybe at oil
changes). If yours is stuck, don't grab a wrench or pliers--the handle
is fragile--but lightly tap the spring side, maybe with a screwdriver
handle. If you're lucky, that will break the adhesion between the
moving, cone-shaped valve and its body.

 A fine example of British over-engineering.

	 The ON position is at the full counterclockwise rotation of the
handle. 

	 The last time I had the valve off I took it apart, cleaned it, and
applied anti-seize compound to the tapered shaft. Still works very
smoothly.

	 Your photo made me check. It actuall does say off and on the valve.
Still the lever seems ot be half way between off and on. I have
learned not to fix anything that is working. So, 7:30 it is until it
starts leaking someday.

	 Did I miss the answer to the question? Is it closed in the
counterclockwise position? My BJ8 is open (getting heat) with the
lever at the 7:30 position viewed from the front. It has always been
that way. In US plumbing the heat would be off with the lever
perpendicular to the hose and valve.

	Oh, I should have added: Be careful trying to turn, esp. if it hasn't
 been 'exercised' in a while. The handle is fragile (maybe soak in a
 penetrant first). Also, the valve is spring-loaded, if you can push
it
 in and out a few times may help loosen it.
