source needed for brass 4 way rotary valves?

I am trying to get my hands on a pair of the above so as to be able to maintain countercurrent flow across both sides of my plate HX in both charge and discharge modes

like the ones at the bottom of the first page here:

http://na.heating.danfoss.com/PCMPDF/ESBE 3_4 way MG_5_05_08.pdf

since the tank side of my system will be open, the cast iron Honeywells won't work due to likelihood of corrosion

my usual local wholesaler (Granite Group) doesn't deal in these particular Danfoss Items.

I sometimes do OK with Blodgett, but Webb is too highfalutin to deal with a small timer like me

any suggestions of wholesalers or on-line sources for something like this, in a quantity of two valve units?

just what size are you looking for? And 2 or 3 way? I'll see what I can do tomorrow when everyone is open.

Thanks

I want a 4 way, 1.25 ports, in brass. Actually, two of 'em. Sweat fittings are handiest, but I would not say no to NPT.

The Danfoss has a better mounting flange and shaft than the others like the Tekmar, for purposes of what I want to do of running a "ganged pair" of them on the inlet and outlet sides of a plate HX, to be able to take a pair of these 4 way valves and run them together, with some combination of toothed belts or pulleys, and a stepper motor or other actuator, weights, and chains, or something of the sort to be able to quickly and easily swap directions of flow on both sides of the HX, so as to maintain countercurrent flow on both sides of my plate HX, and maximum retention of stratification in the tank, both when the boiler is charging the tank and when the boiler is cold and the tank is the source of heat for the house.

Ray at Capital/ Granite Group told me that they don't deal in Danfoss of this size, and that whatever else that they can get in anything other than the Honeywell iron units will drive me to the poorhouse. As I mentiioned above, Blodgetts is a pain to deal with, and Webb is too snooty to deal with me, so I appreciate any and all help!
