"Send a signal
Mark 95AA Series
not a
technician"
Sanitary Air Augmented Back Pressure Regulators
The Mark 95 with air augmentation (AA) option offers
the same line sizes, Cv choices, seats, low build up
characteristics, and stability of the standard bolted
bonnet Mark 95, but with an advantage. By connecting an air pressure signal to the 1/4" FNPT dome
tting via an air regulator or I/P, the set point can be
changed remotely by "sending an air signal instead of
a technician".
The Mark 95AA and Mark 95AAFT gives users the
ability to change pressure set points. Adjustments can
be made with air pressure instead of, or in conjunction with, manual adjustment of the spring force to any
point in excess of the springs minimum set point (2 psi
on a 3/4" – 1" Mark 95, 3 psi on a 1-1/2", and 5 psi on
a 2"). Users adjust the regulator's spring to the lowest
set point (2 psi on a 3/4" for example), or to the lowest
set pressure that the regulator will normally operate at
(sterilization steam pressure for example), and use air
pressure to charge the setpoint. To lower the set point
to it's previous value, the pressure is reduced in the
same manner.
Sanitary Valves Mark 95AA Sanitary Back Pressure Regulators
The Mark 95AA and Mark 95AAFT are used in con-
junction with a Steriow self relieving I/P for control via
PLC or DCS, or with a JSRLF regulator with self relieving option (For example - for remote control by valve
mounted on wall, or panel outside of a cleanroom.)
Features
• Reduce project CapEx. Remote regulator operation reduces the time required for system balanc-
ing, commissioning and validation of SIP and CIP
routines.
• Complete range of products for any size or Cv
requirement. The available sizes and Cv's are the
same as the current MK95 product line.
• Mark 95AA and Mark 95AAFT upgrade kits
available for currently istalled MK95 regulators.
• With preset spring, users maintain control in the event
of power (air failure). Valve will return to manual preset.
• Minimal build up when compared with
all other spring loaded and air operated
products, especially at higher set points.
• Extended permissible operating range
when compared with all spring loaded and
air load regulators.

sample speciFication
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 certied 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.
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 Steriow SFCV sizing program. If you do not have a copy of the sizing program,
go to www.steriowvalve.com and click on Technical/Valve Sizing Program or call your local Steriow
representative.
3. If the actual Cv, or ow rate (if solving for ow rate), are not sufcient 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 Retrot Kit for an existing Mark 95, you must provide the serial number of the
Mark 95 with your RFQ or order.
