Large commercially available exhaust valves

I have a decade old memory of somebody selling a 4" quick exhaust valve (or similar) that was rated to something like 400 psi. A quick google isn't turning up anything but my google fu has always sucked. I know this is beyond the normal stuff, but if there's a group of folks on the internet who will have the knowledge of who makes some random high speed valve and where to find it, it's you folks.

This ring a bell for anyone?

For personal or "work" related?

There are some 4" sprinkler type valves that come up, but nothing had more than 150psi rating.

For personal and on a budget...large toolies piston?

If you need approvals and have tax dollars to spend, you could drop Emerson a line and ask about piloted relief valves. Anderson Greenwood has something that might be made to work...not sure how quick it'll open as supplied, but it's basically a big ass qev.

Goyen brand larger diameter valves used here, not sure if they go up to 4" though.
