Spring-Return actuators
Important
When replacing spring cartridges in a spring-return actuator, ensure that the cartridges are
replaced in their identical position from where they were removed.
Check below figure to see where to place the spring cartridges in case of spring set
conversion.
Before assembling the spring cartridges and end caps, make sure that the pistons are
completely inwards.
