4-way valves
4-way valves
(OP)
For a groundwater remediation project I've designed an aboveground pump skid to pump groundwater out of one zone, add an amendment and then reinject into a different zone. One desired feature is to be able to reverse the flow, ie switch the extraction and injection zones. It seems to me that an LL-ported 4-way ball valve would be ideal. However, I'm having a tough time finding a source that is on my client's (large chemical company with global standards for how they want things done) approved manufacturer's list.
Can anyone recommend a good quality 4-way valve, or an alternative, say a 4-way plug valve? My fall-back position is to use two 3-way valves.
I'm pumping groundwater containing high concentrations of chlorinated solvents (carbon tet and PCE), high chlorides and sulfides. Average flowrate: 3-12 gpm. Average pressure: 10-30 psi. Piping is all 1" 316L SS.

I had not come across this source. Unfortunately, I am in the USA and their distributors are only in Europe and Africa. I have found a couple of suppliers that are not on the approved vendor/manufacturer list for my client.
Are 4-way ball valves generally not accepable in the petrochemical industry, or is it that there is such a limited use for them that few manufacturers make them?
