Back Pressure Internally Piloted Pressure Regulators
The Mark 52 internally piloted back pressure regulator is a specialty valve designed for critical application
regulation in locations where space is limited. Small
and lightweight in design, the MK52 valve provides the
accuracy of a piloted valve with the size, weight and
appearance of a single, self-operated valve.

The MK52 will accurately control pressure with little deviation from the set point, therefore the MK52 should
be considered before other more expensive, sophisticated control instrumentation.
The compact design and simple construction allows
fast, simple installation and easy servicing. The high
turndown ratios go up to 100:0.

Operation
The operation of the Mark 52 is very similar to that of an
externally mounted piloted regulator. The main valve
and the pilot are normally closed. The inlet pressure
passes through the inlet pilot tubing beneath the pilot
diaphragm. When the set point is reached, the force of
the adjusting spring is overcome, and the pilot valve
opens. This allows the inlet pressure to enter the chamber above the main diaphragm and opens the main
valve. When the pressure drops below the set point,
the adjusting spring overcomes the force of the pressure beneath the pilot diaphragm and the pilot and
main valve closes.

Mark 52 Back Pressure Internally Piloted Pressure Regulators

As the Mark 52 is self operating, it is suitable for use
in locations where accurate regulation is needed, but
air or electric supply may not be readily available.
With the compact design, limited space applications
is no problem, making it ideal for use on skids, or as
an upgraded replacement for smaller regulators. The
integral pilot design also means lighter weight, placing
less stress on support piping.
