Differential, Jorlon Diaphragm

The Mark 53 is designed to maintain inlet pressure at a set differential pressure over the signal pressure loaded on the diaphragm. The Mark 54 provides the same flow capacity but with less offset in controlled pressure due to a larger diaphragm. It can be used for both differential and remotely adjusted applications. A negative differential version is also available.

Features & Benefits
  • Maintains a constant differential between the inlet pressure and the pressure loaded to the top of the diaphragm
  • Straight-through flow for reduced turbulence and quiet operation
  • Short stroke for fast response and accurate regulation
  • Easily interchangeable CV’s
  • Tight shutoff
