DESCRIPTION
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
