6 Installation Instructions
Installation work of any kind for the actuator may only be performed by qualified personnel.
6.1 Mechanical connection; preparations:
Check,
• whether valve flange and actuator base match
• if the bore of the coupling piece coincides with the spindle pin and sufficient thread engagement is available
NOTE: Make sure that both the valve and the actuator are in the failsafe position.
General procedure:
• Clean the bare parts on the actuator coated with rust protectant.
• Clean the mounting surface for the fitting thoroughly.
• Lightly grease the valve stem.
• Put the actuator on the valve.
• Pay attention to the centered position and full support surface of the flanges.
• Fasten the actuator with suitable bolts:
– Minimum strength grade: 8.8 or A2-70
– Ensure sufficient thread engagement (min. 1xd)
CAUTION: Screws that are too long may go against the thread root, creating the risk of the actuator moving
radially vis-à-vis the fitting. This may lead to the bolts shearing off.
NOTE: Unsuitable bolts may result in the actuator falling off!
• Tighten bolts to the correct torque, alternating between bolts on opposite sides
