Mark 978 Series
Sanitary Control Valves - JD Version
The Mark 978-JD (Jorlon Diaphragm) Series is de-
signed to meet the rigid specications for sterile process
and clean utility control valves. This valve series is
suitable for a wide variety of applications in the, bio-
pharmaceutical, Parenteral, cosmetic, dairy and food
and beverage industries.
The Mark 978 meets ASME BPE 2009 guidelines, and
is ideally suited for a wide range of owing 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
and acid metering, and clean gas and steam services.
Whether the need is to control pressure, temperature,
ow, pH, or another variable, the MK978 is the right
valve for your process.
