2.1 Intended use
The T.VIS M-15 control top can be used for the pneumatic and electrical
connection of all Tuchenhagen process valves with VARIVENT adaptation. Using
the device for any other purpose is considered contrary to its designated use.
The control top T.VIS M-15 is available as
• position indicator without solenoid valve
• with solenoid valve as control top
The control top T.VIS M-15 is completely installed on the dedicated actuator/
adapter of the process valve by means of a clamp connection. Due to the internal
air guiding system, the control air can pass directly from the control top into the
actuator on suitable process valves. For process valves which do not allow the air
to be guided internally, the control top has a connection option for supplying the
air externally via a hose.
With T.VIS M-15 the following can be carried out for all valves:
• monitoring the non-actuated position of the valve disk,
•
monitoring the actuated position of the valve disk,
• provision of an PNP or NPN output for feedback signals,
• coloured visualization of the valve position and status via the illuminated
dome fitted on the control top.
In addition, with T.VIS M-15 you can monitor the non-actuated position of the
double-disk with an initiator in the lantern for all double-seat valves.
The control top T.VIS M-15 may not be used in areas where ATEX approval is
required.
Hint!
The manufacturer will not accept any liability for damage resulting
from any use of the valve which is not in accordance with the
designated use of the valve. The risk is borne solely by the operating
company.
