Hi Kelly,
Many months ago, B777 said that PST would develop and sell a FOD screen for PST turbines, the 600R in my case. Is that endeavor still on going? When will a FOD screen be available?

Is there a 4mm ball valve available with a mount flange? The ball valve provided with the turbine does not have a mount flange....on my new model a flange would make mounting a bit easier. Cost?

Thanks,
Keith
