Mark 95 Series
Sanitary Back Pressure Regulators
The Mark 95 is available with a hard or soft seat
and a variety of diaphragm and o-ring materials,
making the valve well-suited for virtually any sterile
back pressure application.
The Mark95 operates by sensing the inlet pres-
sure, or back pressure, beneath the diaphragm, as
ow enters from inlet port on the side. As the back
pressure exceeds the setpoint, the diaphragm force
compresses the range spring permitting the stem
to move from the seat toward the open position. As
the ow increases, the back pressure is relieved
and the spring and diaphragm relax, allowing the
stem to return to the normally closed position. If a
different set point is desired, a simple turn of the
adjusting screw will increase or decrease the set-
ting to any set point within the range covered by the
regulator's spring.
