The only dual output valve that Pingel offers is 3/8". Would there be much advantage over stock on a single output with a splitter?

single with a splitter is fine

Why not use 1/8" NPT or BSP thread? Or do Pingel only supply 1/4"?

easier to find a 1/4" NPT with reserve. bsp, not common here. ( I actually work in the valve industry).

I know NPT is the US standard, from endless issues with people mixing BSP and NPT on the offshore equipment I work with. Most all major hydraulic valve, pump and motor manufacturers use parallel thread BSP in their ports, due to the "wedging" action of the tapered NPT, which can cause minor deformation in housings.....

or sae ;) (at least here). I'm familiar with both, we get requests for BSPP and G thread on occasion, its just hard to source, which really sucks as we have missed out on a few good orders. as an fyi though, 1/4 bsp & npt 1/4 will interchange within 1 thread difference in engagement, that's the ONLY one you can really 'fudge' and get away with , ive tested it up to 5000 psi here . (air over water setup)

boy did this drift off topic

Well I learned something.

BTW my math was way off on the 3/8npt petcock. Even the 1/4"npt only gets at best 2mm of gap between screw holes....
