DESCRIPTION

Differential, Jorlon Diaphragm

The 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 but with less offset in controlled pressure due to a larger diaphragm. This series is ideal in fuel oil atomization applications. A negative differential version is also available.

Features & Benefits

  • Mark 63/64 maintains a constant differential between the pressure on the discharged side of the regulator and the signal pressure loaded on the diaphragm. The Mark 64 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
  • All Jordan Valve’s differential pressure regulators feature advanced sliding gate seat technology
