    Why doesn't the actuator stem move on demand in my Samson Controller?
    • H
      Heather HernandezAug 18, 2025
      The actuator stem might not move due to several reasons. It could be blocked; check the attachment and remove any blockage, remembering to disconnect and lock the pneumatic air supply and control signal before unblocking, and release any stored energy in the actuator. Insufficient signal pressure is another possibility; in this case, check the signal pressure and the signal pressure line for leakage. Also, the signal pressure might not be connected to the correct diaphragm chamber. Finally, the diaphragm in the actuator might be defective.

    What to do if the actuator stem doesn't stroke fully in my Samson 3277-5 Controller?
    • A
      Angela WilliamsAug 20, 2025
      If the actuator stem isn't stroking through its complete travel range, first check if the travel stop is active. Then, verify the signal pressure and check the signal pressure line for any leaks. Finally, examine the settings of the valve accessories, first checking the actuator without valve accessories.

    Why is my Samson Control Unit valve leaking to the atmosphere?
    • M
      Megan WelchAug 23, 2025
      The valve might be leaking due to several reasons: * Defective packing: Consider replacing the packing. * Adjustable packing not tightened correctly: Ensure the packing is tightened correctly. * Loose flanged joints or worn-out body gaskets: Check the flanged joints and replace the gaskets if necessary. * Bellows seal defective: If your unit has a bellows seal, it might be defective.

    What to do if there is increased flow through my closed Samson Control Unit valve?
    • S

      If you observe increased flow through a closed valve, it could be due to: * Dirt or foreign particles: Shut off the pipeline section and flush the valve to remove any deposits between the seat and plug.

    Why doesn't the actuator and plug stem stroke through the full range on my Samson Control Unit?
    • J
      Jake ParkerAug 28, 2025
      The actuator and plug stem might not stroke fully due to: * Signal pressure too low: Check the signal pressure and inspect the signal pressure line for leaks. * Incorrect setting of valve accessories: Verify the settings of the valve accessories.

    How to troubleshoot an actuator that doesn't move on demand in a Samson Control Unit?
    • J
      James JohnsonAug 30, 2025
      If the actuator and plug stem do not move on demand, consider the following: * Actuator blockage: Put the control valve out of operation and remove the blockage. * Signal pressure too low: Check the signal pressure and the signal pressure line for leakage.

    What causes jolting movement of the actuator and plug stem in a Samson Control Unit?
    • A
      Anita AlexanderSep 2, 2025
      If you experience jolting movement, it might be because the packing is tightened too far. Tighten the packing correctly.

    What to do if there is increased flow through closed Samson Control Unit valve?
    • A
      Ashley RitterSep 5, 2025
      If you observe increased flow through a closed valve, it could be due to dirt or foreign particles deposited between the seat and plug. Try shutting off the section of the pipeline and flushing the valve. Another reason could be worn valve trim, especially with a soft seat. In this case, replace the seat and plug.

    How to troubleshoot a Samson Control Unit actuator that doesn't move on demand?
    • N
      Nicole FlemingSep 7, 2025
      If the actuator and plug stem do not move on demand, the actuator might be blocked; check the attachment and unblock it. Another cause may be that the signal pressure is too low; check the signal pressure and the signal pressure line for leakage. A defective diaphragm in the actuator could also be the cause.

    Why Samson Control Unit actuator doesn't stroke through the entire range?
    • J
      Jennifer FreemanSep 10, 2025
      If the actuator and plug stem do not stroke through the entire range, this could be due to several reasons. The signal pressure might be too low, so check the signal pressure and the signal pressure line for leakage. It may also be that the travel stop is active, or the valve accessories are incorrectly set; in that case check the settings of the valve accessories.
