To Next PageTo Next PageWhat to do if the actuator and plug stem doesn't stroke through the entire range in my Samson Control Unit?
If the actuator and plug stem of your Samson Control Unit do not move through the entire range, first check the signal pressure and signal pressure line for any leakage. Also, verify the settings of the valve accessories.
How to fix actuator and plug stem if it does not move on demand in Samson 3251?
If the actuator and plug stem of your Samson Control Unit do not move on demand, the actuator might be blocked. Check the attachment and remove any blockage. Be careful, as a blocked actuator or plug stem can suddenly move uncontrollably. Disconnect and lock the pneumatic air supply and control signal before attempting to unblock it, and release any stored energy in the actuator. Also, check the signal pressure and signal pressure line for leakage.
What to do if there is increased flow through closed valve (seat leakage) in Samson 3251?
If you notice increased flow through a closed Samson Control Unit valve, it might be due to dirt or foreign particles deposited between the seat and plug. Try shutting off the pipeline section and flushing the valve to remove any debris.
What to do if the Samson Control Unit actuator doesn't move?
If the actuator and plug stem of your Samson Control Unit do not move when expected, there could be a few reasons. First, the actuator might be blocked; inspect the attachment and remove any blockage, but be careful, as a blocked actuator can suddenly move uncontrollably once unblocked. Ensure you disconnect and lock the pneumatic air supply and control signal before attempting to unblock it, releasing any stored energy. Also, the signal pressure might be too low, so check the signal pressure and the signal pressure line for any leakage. If these steps don't resolve the issue, the diaphragm in the actuator might be defective.
Why Samson Control Unit actuator doesn't stroke fully?
If the actuator and plug stem of your Samson Control Unit aren't stroking through the entire range, there might be a problem with the signal pressure being too low, so you should check the signal pressure and signal pressure line for leaks. Also, the travel stop might be active, or the valve accessories might be set incorrectly. Check the settings of the valve accessories.
