is ideally suited for a wide range of flowing media in
both the clean utility and process areas of sanitary and
aseptic systems.
High rangeability, true characterized trim, high capaci-
ties, superior temperature and pressure ratings, facili-
tated by a superior diaphragm, make the MK978 the
sanitary control valve for sterile process, buffer, WFI
