Intended Purpose
Designated 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 T.VIS M-15 control top is available as
•
position indicator without solenoid valve
•
control top with solenoid valve
The complete T.VIS M-15 control top is mounted on the actuator/adapter of the process
valve provided for this purpose using 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.
T.VIS M-15 allows the following on 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.
T.VIS M-15 in addition allows on all double-seat valves the non-actuated position of the
double-disk to be monitored via a proximity switch in the lantern.
The T.VIS M-15 control top may not be used in areas which require ATEX approval.
NOTE
The manufacturer will not accept any liability for damage resulting from any use of the
control top which is not in accordance with its designated use. The risk of such misuse
lies entirely with the operator of the facility.
Requirements for the Operation
The prerequisite for the reliable and safe operation of the control top is proper transpor-
tation and storage as well as professional installation and assembly. Operating the valve
within the limits of its designated use also involves adhering to the operating, inspection
and maintenance instructions.
