Lever-Lock Handlever Actuators for

Fisherr A41 and A11 Valves

The lever-lock handlever actuator is used for reliable

manual operation of NPS 3 through 8 Fisher A41 and

NPS 3 and 4 A11 high-performance butterfly valves.

Spring loading secures the handlever in the notched

quadrant plate, allowing the valve disc to be locked in

intermediate positions.

actuator consists of ductile iron quadrant plate,

handle, and grip.

 Monitoring Ease–Lever-lock handlever

configuration offers positive on/off and

intermediate locked positions for throttling control.

 Tamper Resistant–Handle can be provided with

padlock for tamper-resistant open/closed position.

 Accessory Mounting Available–Limit switches can

be mounted to the handlever actuator for remote

valve position indication.

 Adjustable Travel Stops–Positioning device

available for setting repeatable stops from 0 to 90

degrees rotation.
