4.2 Description
The GEMÜ 1435 ePos digital electro-pneumatic positioner is
used to control pneumatically operated process valves with
single acting or double acting linear or quarter turn actuators,
and detects the position of the valve using an external travel
sensor. It has a robust aluminium housing with protected op-
erating keys and an LCD display which allows the product to
be individually adapted to the control task. The travel times
can be set using integrated throttles. Connection and mount-
ing to NAMUR is also possible. Therefore, the GEMÜ 1435
ePos is an optimal solution for control tasks with high require-
ments, especially in applications with harsh environmental
conditions.
