What to do if my Samson 3374 Controller actuator does not control the valve position?
If the Samson Controller actuator isn't controlling the valve position, it might be because the actuator wasn't initialized properly during start-up, or the mounting has been changed. You should initialize the actuator and take corrective action according to the error code (see Chapter 9.2).
Why is the actuator stem on my Samson Controller not moving?
The actuator stem on your Samson Controller might not be moving due to a blockage in the actuator attachment, or because there's no or incorrect supply voltage connected. Check the attachment and remove any blockage. Also, verify the supply voltage and connections.
What to do if the Samson Control Unit valve leaks to the atmosphere?
If the Samson Control Unit valve leaks to the atmosphere, it could be due to a defective plug stem seal or a loose flanged joint with a worn-out gasket. You should check the flanged joint. For a defective plug stem seal, it is recommended to contact our after-sales service.
Why does the Samson Control Unit actuator and plug stem not move on demand?
If the actuator and plug stem of your Samson Control Unit do not move on demand, it could be because the actuator is blocked or there's no or incorrect supply voltage connected. Check the attachment and remove any blockage. Also, check the supply voltage and connections.
What to do if there is increased flow through closed Samson Control Unit valve?
If you observe increased flow through a closed Samson Control Unit valve, it might be caused by dirt or foreign particles between the seat and plug, or the valve trim could be worn out. To resolve this, shut off the section of the pipeline and flush the valve. If the valve trim is worn, contact our after-sales service.
Why actuator and plug stem does not stroke through the full range in Samson Control Unit?
If the actuator and plug stem of your Samson Control Unit don't stroke through the full range, the cause may be no or incorrect supply voltage connected. Ensure that you check the supply voltage and connections.
What to do if flow rate exceeds adjusted set point on Samson Control Unit?
If the flow rate exceeds the adjusted set point on your Samson Control Unit, it could be due to several reasons. First, check for insufficient pressure pulses on the operating diaphragm and clean the control line and screw fittings. Foreign particles might be blocking the plug; if so, remove them and replace any damaged parts. The seat and plug could be worn or leaking, requiring replacement. Also, the valve might be too large or too small for the control task, so check the sizing and change the K /C coefficient if necessary, or install a different sized regulator. Finally, a defective operating diaphragm can cause this issue, so replace it if damaged.
Why does flow rate fluctuate on Samson Control Unit?
If the flow rate fluctuates in your Samson Control Unit, it might be because the regulator or K /C coefficient is too large. To solve this, check the sizing and change the K /C coefficient if necessary, or install a different sized regulator. Another possible cause is that the restriction in the control line for pressure tapping is too large or missing. In this case, install a restriction or install a smaller restriction.
How to fix slow control response on Samson Control Unit?
If you are experiencing slow control response with your Samson Control Unit, it could be due to a restriction in the screw joint of the actuator being dirty or too small. Try cleaning the screw joint or installing a larger one. Another cause could be dirt in the control line, so make sure to clean the control line.
What to do if there is leakage at the actuator of Samson Control Unit?
If you notice leakage at the actuator of your Samson Control Unit, the operating diaphragm might be defective. Replace the damaged diaphragm to resolve this issue.
