It would be good to know if there is any interest in using alternative valves -

These are high spec large bore specifically designed for wvo/svo use with a solenoid operation, ie only need a single pulse to switch and not continuous current.

Rough prices at the moment would be £100 UK sterling a pair + shipping for a minium of 6 pairs.

I'll move this post across to the correct thread and post further details if peeps are interested.
EDIT: I have copied it here from the original location and changed the thread title. Tony
