4.2.1 Installing position of the Actuator and the Positioner
Fig.4-3a Mounting positions of the Actuator
Installation position A, A (→ Fig. 4-3a) - perpendicular
to the pipeline is the standard mounting for both Actuators
and Positioners. Mounting positions B, C, D for Actuator
(→ Fig. 4-3a) and the Positioner → Fig. 4-3ab) can be selected
depending on the installation option.
The Valve and Actuators mounting position
relative the horizontal line. A mounting position with the
Valve shaft pointing upwards (vertical) is often considered to
be standard. If the media contains sticky or other difficult
impurities, that tend to collect at the bottom of the pipe, it is
advised to mount the valve with an angle of vertical.
Fig.4-3ab Mounting positions of the Positioner
In this way it is avoided that the impurities collect and
eventually clog and glue the bottom bearing of the valve shaft.
Fig.4-3b Mounting position
When large actuators (both single - and double acting) are used in vertical pipes, install them with
the cylinder in the pipe direction. This will result in less wear and easier maintenance. (
➔ Fig.4-3b).
