Sir, A very good explanation of spring and diaphragm actuators. Thanks for uploading!

Amazing! Very nice

It's also important when setting up a positioner on an actuator, for a Fail-closed valve assembly, that when closed that the actuator is fully vented. And with a fail- open valve assembly, that the actuator when the valve is full closed, that the actuator is fully pressurized. This ensures that the seat load is adequate to meet its seating criteria class.

Does it actuate pneumatically or electrically?

[@FisherControlValve]

Spring and diaphragm actuators are powered pneumatically

[@lifeisbeautiful1556]

Or in case of high pressure steam line?
