Item 1: Actuator flange
Item 2: Adapter for valve spindle
7. Valve mounting
The PSQ-E actuators are provided with a mechanical interface according to ISO 5211 for valve mounting.
The gear does contain an internal octagon SW22 to connect the actuator to the valve shaft.
Figure 5: Actuator flange
Check if the actuator flange suits the valve flange
If required, use standard adapters to adapt to the
valve shaft
Clean the surface of the connection components,
lubricate valve shaft slightly
Position the actuator on the valve
Tighten the screws in a diagonal sequence according
to the required torque
For valve mounting please ensure that the
cover of the actuator is always closed in order
to avoid that components inside the actuator
are damaged.
8. Setting of the mechanical stop
There are two adjustable screws installed for setting the mechanical limit of the angular travel.
When setting the mechanical end positions, only the handwheel may be used. Do not
operate the actuator electrically.
Remove the protection cap (, item 3) from either stop screw.
Unscrew both stop screws anti-clockwise by approximately 5 turns.
Move the actuator to the closed position by turning the handwheel clockwise.
Turn the stop screw for closed position (, item 1) to the stop.
Move the actuator to the open position by turning the handwheel anti-clockwise.
Turn the stop screw for open position (, item 2) finger tight.
Screw on the protection cap onto the stop screw.
