Mark 96aa SerieS Sanitary air augMented PreSSure regulatorS
sample speciFication
Stainless steel sanitary pressure regulator shall be made from ASME-SA479 barstock material,
which includes body and all wetted metal parts. Regulator shall utilize FDA approved, USP Class
VI certied Jorlon diaphragm. Regulator shall be fully and remotely adjustable with the addition of a
pneumatic air signal, to any set point above the minimum spring set point up to a maximum of 135
psi for sizes 1" and below; 80 psi for 1-1/2" and above. In the event of air system failure, valve shall
be manually adjustable. Guiding of valve stem/plug shall be outside of the wetted process areas of
valve internals, above diaphragm. Regulator shall be free of threads within wetted, process areas
and shall be self draining when installed with inlet vertical and below valve assembly.
sizing anD selection
In order to nd out the actual Cv and/or ow rates for your application, complete the following:
1. Select the appropriate line size, required nominal Cv, and set point spring for your application from
the charts on page 2, or from the ordering grid below.
2. Input that data, along with the installation inlet pressure, desired outlet pressure set point, and other
required data into the Steriow SFCV sizing program. If you do not have a copy of the sizing program,
call your local Steriow representative or request a copy by email to steri[e-mail].
3. If the actual Cv, or ow rate (if solving for ow rate), are not sufcient for your application, then select
and input a more appropriate valve Cv for that line size until you get an actual Cv that will work in
your application. Note: If the actual Cv generated by the program is still not appropriate, you may be
required to input a different valve line size, in order to obtain the correct Cv. Note, never select an
automated valve by line size only.
Note: if ordering a Retrot Kit for an existing Mark 96, you must provide the serial number of the
Mark 96 with your RFQ or order.

Consult factory for parts to retrot a MK96 into a MK96AA. Retrot kits may not be available with some MK96
project valves and valve models older than 2002. The valve serial number will identify your MK96's bill of material and is
required for proper retrot selection.
