Differential Pressure Regulators; Sliding Gate Seat; 1/4″ – 2″ (DN8 – DN50); The Mark 63 - differential pressure regulator 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 differential pressure regulator valve series is ideal in fuel oil atomization applications. A negative differential version is also available.

Differential, Jorlon Diaphragm The Mark 53 and 54 Series transform challenging differential pressure control into reliable, repeatable operation. By maintaining a precise pressure differential between inlet and signal pressure, these valves enable sophisticated process control strategies – from maintaining consistent pressure drops across filters and strainers to managing complex reactor pressure profiles. When your process depends on maintaining exact pressure relationships, not just absolute pressures, these differential pressure valves deliver the control intelligence you need.
