Caution!
Actuators and valves refer to the table on the last page and folding leaflet "Leporello", Z-B01350501EN
• The thread of all the actuators is such that they can be fitted to both "push-to-open" and "pull-to-open" valves.
• However, RX applications do not support inverse control. In other words "pull-to-open" valves may be fitted only with pull-action
actuators, and "push-to-open" valves only with push-action actuators.
• This means that the valve / actuator assemblies in all RX applications are always closed when de-energized.
Parallel operation of thermic actuators:
• Irrespective of the manufacturer, the configuration should be "3rd party thermic".
