    What to do if the actuator and plug stem of my Samson Control Unit does not move?
    • Z
      zjohnsonSep 8, 2025
      If the actuator and plug stem do not move on demand, it could be due to the following reasons: * The actuator is blocked. Check the attachment and remove any blockage. Be careful, a blocked actuator or plug stem can suddenly start to move uncontrollably. Disconnect and lock the pneumatic air supply and control signal before unblocking. Release any stored energy in the actuator before unblocking. * The diaphragm in the actuator is defective. Please, refer to the associated actuator documentation for guidance. * The signal pressure is too low. Check the signal pressure and the signal pressure line for any leakage.

    Why doesn't the actuator and plug stem stroke through the entire range on my Samson Control Unit?
    • P
      Paul PhillipsSep 10, 2025
      If the actuator and plug stem do not stroke through the entire range, consider these potential causes: * The signal pressure may be too low. Inspect the signal pressure and check the signal pressure line for leaks. * The plug may have become detached. Fasten the plug and plug stem together. * The valve accessories might be set incorrectly. Verify the settings of the valve accessories.

    What to do if there is increased flow through a closed Samson Control Unit valve?
    • B
      Beverly SellersSep 12, 2025
      If you observe increased flow through a closed valve (seat leakage), the following could be the cause: * Dirt or other foreign particles may be deposited between the seat and plug. Shut off the pipeline section and flush the valve. * The valve trim, particularly with a soft seat, may be worn. Replace the plug or contact after-sales service.

    How to fix jolting movement of the actuator and plug stem in my Samson Control Unit?
    • R
      Robert DawsonSep 13, 2025
      If you're experiencing jolting movement of the actuator and plug stem, and you have a version with adjustable packing, the packing might be tightened too far. To resolve this, tighten the packing correctly. Refer to the 'Adjusting the packing' information in the 'Installation' section under 'Testing the installed valve'.

    Why won't the actuator stem move on demand in my Samson Controller?
    • G
      gregory19Sep 15, 2025
      The actuator stem might not move on demand due to several reasons. It could be blocked; in this case, check the attachment and remove any blockage. Another cause might be insufficient signal pressure, so check the signal pressure and the signal pressure line for leakage.

    What to do if the actuator stem doesn't stroke through its complete travel range on a Samson 3277?
    • M
      martinezrebeccaSep 18, 2025
      If the actuator stem does not stroke through its complete travel range, it could be due to insufficient signal pressure. Therefore, check the signal pressure and the signal pressure line for leakage. Another possible cause is incorrect setting of valve accessories, so check the actuator without valve accessories and then check the settings of the valve accessories.
