Not quite.
For a 2 port zone valve is as follows.
Grey = permanent live feed to valve from wiring centre
Brown = switched live into valve from clock/stat
Orange = switched live out of valve to pump/boiler
The white wire is only present on a "mid position valve" and is used as a hot water off signal from the stat to allow the heating to run seperately.
There is a difference in the connections as the grey powers the motor in the valve and the orange is on the load side of the microswitch.
