Drayton Zone Valve (2 Port). What way round?

[willing2try]

Hey all,

I have a motorised Drayton Zone Valve (2 Port) and I'm wondering what way round these should be fitted? On the valve body (brass) are the letters 'A' and 'B'. The natural state of this valve is closed (position 'A'). Is the 'A' the inlet and the 'B' the outlet?

Many thanks in advance.

Ashley

"a" is inlet, pump side.

"b" is outlet, rad or cylinder side.
