  Kristen HillAug 12, 2025
  If you observe increased flow through a closed Samson Control Unit valve, it could be due to dirt or foreign particles lodged between the seat and plug. Try shutting off the pipeline section and flushing the valve to remove any debris. Alternatively, the valve trim, especially with a soft seat, might be worn. In this case, you would need to replace the seat and plug.

Why does the Samson Control Unit valve leak to the atmosphere (fugitive emissions)?

  pwilliamsAug 19, 2025
  A Samson Control Unit valve may leak to the atmosphere due to several reasons. It could be caused by defective packing, or if it's a version with adjustable packing, the packing might not be tightened correctly. Another possibility is loose flanged joints or worn-out body gaskets. Check the flanged joints. If the issue persists, replace the gaskets at the flanged joints.

  If the actuator and plug stem in your Samson Control Unit do not move on demand, first check if the actuator is blocked and remove the blockage. You can put the control valve out of operation. Also, verify the signal pressure and check the signal pressure line for any leakage. If the diaphragm in the actuator is defective, consult the actuator documentation.

  If the actuator and plug stem in your Samson Control Unit do not stroke through the full range, this could be due to several reasons. Check the signal pressure and inspect the signal pressure line for leaks. Also, the travel stop might be active. Furthermore, incorrect settings of valve accessories can cause this issue, so check the settings of the valve accessories.
