Pressure Regulators 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 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. 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 Specifications Sizes: (Note: 1/4" (DN8) & 3/8"(DN12) use 1/2" (DN15) body with reducer bushings) • Mark 63: 1/4" (DN8) through 2" (DN50) • Mark 64: 1/4" (DN8) through 3/4" (DN20) • Mark 63CDF: 2-1/2" (DN65 through 4" (DN100) End Connections: • Threaded — FNPT, BSPT, BSPP • ANSI Flanges — 150#, 300# • DIN Flanges — PN10/16, PN25/40 Body Materials: • Ductile Iron • Bronze • Carbon Steel — A216 WCB • Stainless Steel — SA351 CF8M Trim Materials: • 303 SST — Standard on Ductile Iron, Bronze, or Carbon Steel valves • 316SST — Standard on Stainless Steel valves Seat Materials: • Jorcote on SST — Standard • Jorcote/Jordanic on SST — For severe service • Chrome Plated SST — Optional Jordan Valve, a division of Richards Industries 3170 Wasson Road • Cincinnati, OH 45209 513.533.5600 • 800.543.7311 • 513.871.0105 (f) info@richardsind.com • www.jordanvalve.com Mark 63/64 Differential Pressure Regulators 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 fluid from mixing in the event that the diaphragm were to rupture.
