Mark 968 Series
Sanitary Gas Regulators sizes 3/4" - 2" for biopharm, pharma, food &
beverage low pressure Clean Dry Gas/Air blanketing and inline
pressure regulation
The Mark 968 Sanitary Gas Regulator is the ideal valve
for low pressure gas regulation in pharmaceutical and
food & beverage applications. The self-contained low
pressure gas regulator is for use on tank blanketing and
other very low critical pressure air and gas applications.
The Mark 968 is normally open. Increases in the outlet
pressure are sensed through the aspirator causing the
large elastomer diaphragm to rise, which moves the
plug toward the seat. As outlet pressure decreases, the
diaphragm moves down and moves the plug away from
the seat to increase flow. The lever, which connects the
stem to the diaphragm, amplifies diaphragm forces for
tighter shutoff (only available on sizes 3/4" and 1").
The large diaphragm and lever actuation allows the
Mark 968 to act with higher sensitivity compared to
smaller diaphragm pressure regulators. High sensitivity
is important, as the Mark 968 often works with very low
pressure (down to 1" w.c. or 2,5 mbar). This special
actuation improves the accuracy and shutoff of the valve
- two important benefits in this style of regulator.
Together, the SST construction, FDA-approved seals
and the tri-clamp connections make this valve well
suited for sterile gas applications and environments.
F
eatures
• Inlet pressures up to 150 psi (10 bar)
• Robust design — emergency outlet pressure may
reach 100% of inlet pressure without damaging
valve
• 360° body orientation — valve can be installed in
any position, and can be easily repositioned while
in-line
• Easy maintenance — seat and plug can be in-
spected without removing body from the line
• Completely self-operated — no external power
source required
• Tight shutoff — soft elastomer plug provides ANSI
Class VI shutoff
• 316/316L SST body/trim and tri-clamp, quick dis-
connect clamp connection
• FDA-approved seals and diaphragms
• Optional electropolishing available
