2.1 Intended use
The T.VIS E-20 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.
Hint!
Correspondingly approved valve control modules and barriers must
be used for the electrical connection.
The control top T.VIS E-20 is available as
•
without solenoid valve as position indicator
•
with solenoid valve as control top
The control top T.VIS E-20 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.
To control different process valve functions, the T.VIS E-20 can be equipped with
up to three solenoid valves. The T.VIS E-20 is able to control a maximum of two
process valves by simultaneous actuation of a maximum of two solenoid valves.
With T.VIS E-20 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,
•
coloured visualization of the valve position and status via the illuminated
dome fitted on the control top.
The control top T.VIS E-20 may be used in areas where ATEX/UKEX, IECEx and
CCCEx approval is required.
The unit can be used in potentially explosive atmospheres as indicated:
•
ATEX (2014/34/EU) *: EU Declaration of Conformity
•
UKEX Directive 2016 No. 1107
•
IECEx*: Certificate of conformity (accessible via database www.iecex.com)
•
CCCEx certificate*
* The T.VIS E-20 must be ordered according to the required approvals.
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.
