Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new modular valve system (MVS) in a chromatography method separating substances on a small scale or a production scale, based on a simulated moving bed method (SMB = countercurrent chromatography). SOLUTION: The modular valve system (MVS) includes a master board provided with at least one valve having a valve housing and a control housing. The control housing internally has an air pressure space separated into a lower control space and an upper control space by a piston provided with a seal, the valve housing and the control housing are mutually connected by a central plate provided with a seal, and the valve housing is disposed on the master board by a seal sheet, using a related seal.
