7.1.2 Plate installation
If a direct installation is not possible because of discrepancy between actuators and valve flanges or because of power transmis-
sion differences, is it possible to use plates. Adapting plates make the installation easier and offer more space for actuator/valve
installation.
7.1 Valve/Actuator installation
7.1.1 Direct installation
Direct installation is the best solution to avoid play or clearance between valve and shaft. Direct installation needs same flanged
standard connection on valve and actuator as well as same dimension of valve stem and actuator socket.
Installation:
A
. Pull reduction in valve stem (in case of reduction needs only);
B
. Put valve stem into the actuator socket;
C
. Verify correct connection to avoid play, clearance or interferences in between;
D
. Place screws (1) and relevant washers (2) and screw them in compliance with below torque
indications;
E
. After installation, check actuator rotation direction for Double acting (DA) actuators;
F
. After installation, check actuator rotation direction and home position in case of Spring Return (SR);
G
. In case of discrepancy contact us;
