Internal Piloted Temperature Regulators
Operation
Reverse Acting MK82 – The internal pilot valve
seats and the main valve seats are up and
closed. As the process temperature rises, the
fluid in the sensing bulb vaporizes to apply pressure to the pilot diaphragm, thus opening the pilot
valve. The upstream pressure passes through
the pilot valve, through the pilot port opening the
main valve to provide the required cooling action.
Direct Acting MK82 – operates as above except
that the pilot valve is normally open and closes
on an increase in temperature.
MK82FS – features a controlled failure option
which allows you to predetermine the position of
the valve in the event of thermal system failure.
It utilizes a vacuum to insure that, if the thermal
system fails, the spring pulls down the pilot diaphragm to open the main valve seats on reverse
acting valves and close the main valve seats on
direct acting valves.
Features
• Sliding Gate Seats – All of Jordan Valve's
pilot-operated temperature regulators feature
advanced sliding gate seat technology
— Straight-through flow for reduced
turbulence, longer life and quiet operation
— Short stroke for fast response and
accurate regulation
— Easily interchangeable Cv's
— Extended tight shutoff due to wear
resistant coatings and overlap of seat
closure area

Mark 82 Internal Piloted Temperature Regulators
As the temperature sensed at the bulb drops, the
pilot valve tends to close, shutting off pressure
to the main valve's diaphragm. The lower spring
closes the main valve as the pressure on the main
diaphragm is bled off through the downstream
port.
