Operating and installation instructions
Pneumatic actuators - FA160-800
5.2 Requirements at the place of installation
The place of installation should be easily accessible and provide ample space for
maintenance and removing the actuator. The valve should preferably installed vertically
with the actuator at the top. Inclined or horizontal installation without supports is permissible
only with light actuators.
Horizontal installation of the valve-actuator combination (refer to Fig. 6 and Fig. 7) is only
permitted if the webs of the valve bonnet are arranged vertically. In case of installation in a
horizontal pipeline (refer to Fig. 7), the valve must be converted prior to retrofitting the
actuator (for mounting the valve top part, refer to "Operating and Installation Instructions
FABA-Supra").
- The actuator can be employed within a temperature range with the min. of -40°C and the
max. of +100°C. By minus temperatures, attention must be given that the control air is dry,
and by high temperatures, if possible, that insulation against heat is provided for.
