Mark 63/64 Series
Differential Pressure Regulators
The Jordan Mark 63 is designed to maintain a constant
differential between the pressure on the discharge side
of the regulator and the signal pressure loaded on the
diaphragm. The Mark 64 provides the same flow capacity
as the Mark 63 but with less offset in controlled
pressure due to a larger diaphragm.
The Mark 63CDF features a flow-through spring housing
that is designed to permit “in-oil-line” installation.
This is especially desirable where air or steam is used
for fuel oil atomization. The fuel oil flow through the
spring housing reduces the possibility of the oil
asphalting on top of the diaphragm which would cause
a loss of differential pressure control and operating sensitivity.
For added protection in this service, the Mark
63CDF includes a separated double diaphragm that prevents
the fluids from mixing in the event the diaphragm
were to rupture.
The regulator is normally open. The outlet pressure
acts beneath the diaphragm and is opposed by the force
of the adjusting spring plus the pressure of the loading
medium. As the outlet pressure overcomes the combined
pressures on top of the diaphragm, the regulator
moves to the closed position.

FEATURES
• Mark 63/64 — maintains a constant differential between
the pressure on the discharge side of the regulator and
the signal pressure loaded on the diaphragm. The MK64
features a larger effective diaphragm area for greater
sensitivity.
• Mark 63CDF — features a flow-through spring housing
for use in controlling atomizing steam or air to oil burners.
• Sliding Gate Seats — all of Jordan Valve’s differential
regulators feature 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
