Mark 85 Series "Controlled Failure" Temperature Regulators Temperature Regulat

Mark 85 Series "Controlled Failure" Temperature Regulators Temperature Regulat
"Controlled Failure" Temperature Regulators
The Mark 85 is a self-operated temperature regulator with controlled failure option which allows you
to predetermine the position of the valve in the
event of a thermal system failure. The Mark 85 is
designed to fail closed on heating application and
to fail open on cooling applications.
Operation
An inherent feature of the controlled failure design
is that it is slower responding than a standard
temperature regulator and cannot compensate
as quickly for rapid load changes. It is ideal for
slower responding systems such as autoclaves
and large storage tanks.
Features
• Rugged actuator long service life
• Replaceable thermal system – can be replaced in the field for range changes. Available with capillaries up to 100 feet long (1,5
meters), although long capillaries should be
avoided if possible
• Sliding Gate Seats – features advanced sliding gate seat technology
— Straight-through flow for reduced
turbulence and quiet operation
— Short stroke for fast response and
accurate regulation
— Easily interchangeable Cv's
— Tight shutoff due to overlap of seat closure

Mark 85 "Controlled Failure" Temperature Regulators
The direct acting Mark 85 is normally open, held
in this position by a vacuum in the thermal system. As the process temperature increases, the
vacuum decreases, allowing the spring to pull
the diaphragm downward to close the seats. A
leak in the thermal system will again decrease the
vacuum and cause the seats to close.
