5.4) Assembly of Valve Figure C:
Before proceeding with the assembly of a valve onto an actuator be sure that the actuator
operates in the desired direction of rotation and both actuator / valve are correctly orientated.
Important : When using a spring return actuator for a fail safe operation, ensure that when air or
electricity failure occurs the direction of rotation is correct for your application.
Fit the valve 5 onto the actuator 3. Ensure that the actuator is in normal position (closed posi-
tion). There are two types of valve assembly onto the actuator :
- Direct-mount : Fit the square of the valve 5 directly into the square of the actuator 3 and bolt
together through the valve ISO pad (max. tightening torque see table above).
- Bracket-mount : Mounting with a bracket 6 and coupling 7, the bracket is bolted to the actua-
tor / valve to join them together and the coupling is used to connect the actuator output drive
to the valve stem (max. tightening torque see table).
5.4.1) Mounting alternatives :
5.4.2) Valve mounting with Actuator Type STANDARD (Clockwise to close) Figure D :
5.4.3) Valve mounting with Actuator Type LF (Clockwise to open) Figure E :
