Rick,
Such a valve is not readily available that I am aware of. Here are some
alternatives ideas:
* Buy a 3 piece stainless steel ball valve (with teflon seals &
seats). These come in socket weld ports or female NPT. Then screw or
weld your own -8 AN fittings on the end. Are you trying to omit a
pipe thread seal? Don't forget to drill a vent hole in the ball
(debur it well so it doesn't scratch the ball seals). Clean it well
too. Add a small film of krytox to the ball and seals when
re-assembling.
* McMaster Carr has these AN port ball valves....
http://www.mcmaster.com/#3710k33/=ue4zy6. Not LOX rated. Also, only
rated to 200 psi. I believe Paul Breed tested one to higher
pressure. You might contact him and ask him for details. Ditto with
the cleaning, krytox'ing, and venting the ball.
* Call Carlos at Norton sales. He may have something.
