  • Extended stroke for each model
  • External tie bars allow contained energy release in event of over-pressure
  • Optional materials of construction for sour service
  • Options include limit switches, relays, solenoids, pressure pilots, dampeners and manual overrides
  • Travel adjustment on top and bottom makes sure the piston stops on the actuator not on the valve, protecting valve seat
