    What to do if the actuator and plug stem on my Samson Control Unit won't move?

      If the actuator and plug stem aren't moving, there could be several reasons. First, the actuator might be blocked; check the attachment and remove any blockage. For electric actuators, verify the supply voltage and connections. If you have a pneumatic actuator, the diaphragm might be defective, so refer to its documentation. Also, check that the signal pressure is adequate and that there are no leaks in the signal pressure line.

    Why doesn't the actuator and plug stem stroke through the entire range on my Samson Control Unit?

      If the actuator and plug stem aren't stroking through the entire range, it could be due to a few reasons. For electric actuators, check the supply voltage and connections to ensure they are correct. If it's a pneumatic actuator, the signal pressure might be too low; inspect the signal pressure and check the signal pressure line for any leakage.

    What to do if there is increased flow through a closed valve (seat leakage) in my Samson Control Unit?

      If you're experiencing increased flow through a closed valve, it's likely due to seat leakage. This can happen if dirt or foreign particles are lodged between the seat and plug. To resolve this, shut off the section of the pipeline and flush the valve.
