Why does the downstream pressure exceed the set point on my Samson Controller?
- ZzedwardsAug 13, 2025
The downstream pressure might exceed the adjusted set point on your Samson Controller due to several potential causes. Insufficient pressure pulses on the operating diaphragm can be a factor; for regulators with an external control line, ensure proper connection of the control line. Blockages can also be responsible: foreign particles blocking the plug, or a blocked control line. The regulator or K /C coefficient might be too large, indicating a need to check the sizing and potentially change the K /C coefficient or install a different sized regulator. For steam applications, the compensation chamber might be incorrectly positioned or too small. A defective operating diaphragm can also contribute to this issue.
