All of Fumotec's valves come from Meinhardt.

Joe I ordered valves from Premacon and they are the exact same as fumotec supply but made of steel. My reasoning was to add a little extra weight to the machine

Hi folks,

yes, I´m using Meinhardt Valves (the big Mega Blocks - i´ve to handle about 2 liters per minute). He don´t support an online shop and he makes not as many as he could sell. Because he don´t need to, it´s not his business, it´s his hobby.
Premacon Valves are fabricated by Jung Fluid. But I can´t tell wether those are open or closed center. I simply would ask premacon via mail.

Hi everybody,

Premacon valves are closed center, i have just received info from them.

by the way, why do you need open center valves? You might run into problems, when using two different motions at once.
And you simply can "simulate" an open center valve by using an additional closed center. You just have to mix it to your working valves in that way, that it opens just in the moment when you don´t use the hydraulic.
