Each actuator is built in the factory to
be either Normally Closed, Normally
Open or Stay-put depending on what
configuration was ordered.
Normally Closed:
Quarter-turn
(spring-return clockwise)
Linear
(spring-return to extend)
Normally Open:
Quarter-turn
(spring-return anti-clockwise)
Linear
(spring-return to retract)
Consult factory if this configuration
needs to be changed as it cannot be
done through software alone.
The actuator can be configured to
either close on Pressure (hydraulic or
spring) for seating valves or Limit for
non-seating valves.
