The Mark 978INLINE Series Sanitary Control Valve (with Jorlon diaphragm) is designed to meet the rigid specifications 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 ANSI BPE 2009 guidelines, and 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 capacities, superior temperature and pressure ratings, facilitated 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.

The Mark 978 Series comes standard with the Jorlon diaphragm. If you are looking to extend the life of your regulators and reduce the overall cost of ownership, then look no further than Steriflow Valve’s Jorlon diaphragm. Jorlon is a structurally modified PTFE with FDA and USP Class VI approval.

Jorlon is a proprietary modified PTFE material that positively impacts regulator reliability, performance and service life. Since its inception, several thousand Steriflow valves with Jorlon diaphragms have been supplied to customers into systems which have been validated by the FDA. Jorlon has been specified in biopharm applications including (but not limited to) WFI, clean steam (up to 100 psig), buffers, acids, cryogenic liquids, clean utility gas, biological intermediates, and final process fluids. Jorlon is warranted for a lifetime of use in our Mark 95, Mark 96, Mark 96AA and Mark 978 Series.

Whether the need is to control pressure, temperature, flow, pH or another variable, the MK978 is the right valve for your process.

Applications: a wide variety of applications exist for the MK978 in the pharmaceutical, biotech, healthcare and food & beverage and other industries including: fermenter, bioreactor, lyophilization, chromatography, SIP/CIP systems, parenteral filling, bio-process, caustic, acids, buffer, clean steam and WFI.
