I am in need of a 3 way 3 stacked ball valve. This is to divert 3 hydraulic lines at 300 Bar from a primary duty pump to a secondary standby pump simultaniously using a single operating lever handle to operate all three valves.
I used this recently to segregate two separate HPU's, but it doesn't come in a 3 port as far as I know.

Arrange the piping so that all 3 valves have their stems lined up on the same axis, and their handles pointed in the same direction. Then weld (or otherwise attach) a common bar to all 3 handles so they operate in unison.
