Stainless steel sanitary back 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-
fied 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 90 psi for sizes 1" and
below; 85 psi for 1-1/2", and 60 psi for 2" & 3". In the event of air system failure, valve shall be manually
adjustable. Guiding of valve stem/plug shall be completely outside of the wetted process areas of valve in-
ternals, above diaphragm per ASME BPE. Regulator shall be free of threads within wetted process areas
and shall be self draining when installed with inlet vertical and below valve assembly.
In order to find out the actual Cv and/or flow 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 Steriflow SFCV sizing program. If you do not have a copy of the sizing program,
go to www.steriflowvalve.com and click on Technical/Valve Sizing Program or call your local Steriflow
representative.
3. If the actual Cv, or flow rate (if solving for flow rate), are not sufficient 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 Retrofit Kit for an existing Mark 95, you must provide the serial number of the
Mark 95 with your RFQ or order.

* Note:
Consult factory for parts to retrofit a MK95 into
a MK95AA. Retrofit kits may not be available for some
MK95 project valves and valve models older than 2002.
The valve serial number will identify your MK95's bill of
material and is required for proper retrofit selection.
