 Sliding Gate Regulators > Mark 63/64 Series



MK63 Series The Mark 63 is designed to maintain an 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.

Features & Benefits




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 63 CDF —features a flow-through spring housing for use in controlling atomizing steam or air to oil burners.
Sliding Gate Seats — all Jordan Valve's differential regulators feature advanced sliding gate seat technology.
