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
".
