Re: heater valves

Huw,

I found the differing heater valve. It may be an older design. The way it
works is a distorted cylinder is rotated, from closed (fully round) to open
(the flat edge recedes progressively exposing a grooved edge and progressing
to a 50% open area). The part number is 171 819 809E. (if my eyes properly
focused on the numbers).


HTH,
