The nominal travel time is 72 seconds at 50 Hz
(60 seconds at 60 Hz) for 90° of rotation. Special Tool Needed
To install the actuator, use a digital voltmeter.
IMPORTANT: Use this VA9104 Series Electric
Non-Spring Return Valve Actuator only to control
valves under normal operating conditions. Where
failure or malfunction of the VA9104 Series electric
actuator could lead to personal injury or property
damage to the controlled equipment or other
property, additional precautions must be designed
into the control system. Incorporate and maintain
other devices such as supervisory or alarm systems
or safety or limit controls intended to warn of, or
protect against, failure or malfunction of the VA9104
Series electric actuator.
IMPORTANT: Utiliser ce VA9104 Series Electric
Non-Spring Return Valve Actuator uniquement pour
commander des équipements dans des conditions
normales de fonctionnement. Lorsqu'une défaillance
ou un dysfonctionnement du VA9104 Series electric
actuator risque de provoquer des blessures ou
d'endommager l'équipement contrôlé ou un autre
équipement, la conception du système de contrôle
doit intégrer des dispositifs de protection
supplémentaires. Veiller dans ce cas à intégrer de
façon permanente d'autres dispositifs, tels que des
systèmes de supervision ou d'alarme, ou des
dispositifs de sécurité ou de limitation, ayant une
fonction d'avertissement ou de protection en cas de
défaillance ou de dysfonctionnement du VA9104
Series electric actuator.

3. Insert the M4x60 long machine screw into the hole
in the handle. Use a No. 2 flat blade screwdriver to
drive the screw into the drive shaft until the screw
is below the top of the handle.
