7. INSTRUCTIONS FOR TOP HANDWHEEL OF ACTUATOR
7.1 Model PSA1 Actuator
7.1.1 Operating Instructions
To manually operate the actuator, refer to Fig. 7-1 and Fig. 7-2 and proceed as follows:
(1) Loosen the lock nut of the handwheel and turn the handwheel in the direction
indicated by the corresponding arrowhead mark.
As you turn the handwheel clockwise, the actuator stem moves downward
regardless of whether the actuator is of the direct action type or reverse action
type. The handwheel bears the "SHUT" mark to indicate that the valve is closed
as the handwheel is turned clockwise and the "OPEN” mark to indicate that the
valve is made open as the handwheel is turned counterclockwise.
(2) For automatic operation of the actuator, fully raise the handwheel if the actuator is
of the direct action type or fully lower the handwheel if the actuator is of reverse
action type, and then tighten the lock nut to secure the handwheel in such position.
Precautions: If you forcefully turn the handwheel after it has reached the
mechanical stop position, the valve stem may be damaged. Do
not turn the handwheel with forces larger than 16 kgf at the
outermost periphery of the handwheel.
