Introduction
Scope of Manual
This instruction manual includes installation,
maintenance, and parts information for the Fisher
Lever‐Lock handlever actuator (figure 1). Refer to
separate instruction manuals for information covering
the control valves.
Do not install, operate, or maintain a Lever‐Lock
actuator without being fully trained and qualified in
valve, actuator, and accessory installation, operation,
and maintenance. To avoid personal injury or property
damage, it is important to carefully read, understand,
and follow all the contents of this manual, including all
safety cautions and warnings. If you have any
questions about these instructions, contact your

Description
The Lever‐Lock handlever is used for reliable manual operation of DN 50 through 150 (NPS 2 through 6) Fisher A81
high‐performance butterfly valves. Spring‐loading secures the handlever in the notched quadrant plate (figure 2),
allowing the valve disk to be locked in intermediate positions. Additionally, the handlever can be locked with a
user‐supplied padlock with 4.8 to 5.2 mm (3/16 to 13/64 inch) shackle to prevent accidental or unauthorized
adjustment (see figures 3 and 4).

Installation
The Lever‐Lock handlever actuator is normally shipped mounted on the valve at the factory. If the handlever was
ordered separately, install the handlever on the valve by following the instructions in this section.
WARNING
Sudden or unexpected movement of the handle can result from unbalanced flow forces. Firmly grip the handlever and
ensure stable footing when operating the handlever to avoid personal injury or property damage.

Installing the Handlever
Orientation
Mount the Lever‐Lock bracket assembly, less the handle, to the valve body. The handle is perpendicular to the pipeline
when the valve is in the shut position. Rotation of the lever/valve shaft in the counter‐clockwise direction will open the
valve. Attach the Lever‐Lock Handlever actuator to the valve in this orientation but do not fully tighten (torque) the
bracket to valve bolting until after the zeroing process below.
Handle assembly
Place the handle and lever assembly on the valve shaft with the valve closed. Squeeze the lever to compress the spring,
position the lever over the notch indicating the closed position, and slide the square cutout portion of the handle over
the valve shaft as far as it will go. Maintain at least a 0.8 mm (1/32 inch) gap between the handle and the plate, so the
handle doesn't rub on the plate during operation. Torque the two hex socket set screws against the shaft to 2.7 NSm
(24 inSlbf).
Zeroing
After tightening the set screws, check the orientation of the disk relative to the body seal retainer. Place a straight
edge on the seal retainer which spans the valve opening. Visually check to ensure there is equal space (within 0.8 mm
[1/32 inch]) between this straight edge and the top and bottom of the disk to ensure the valve is fully engaged in the
seal. To adjust this position, rotate the bracket within the clearance of the mounting bolt holes between the valve
body and bracket. Once there is equal distance between the disk and the straight edge, tighten the mounting bolts to
115 NSm (88 ftSlbf). After tightening, recheck disk position at shutoff to ensure nothing shifted during the tightening
process.

Maintenance
Handlever parts are subject to normal wear/corrosion and must be inspected and replaced when necessary. The
frequency of inspection and replacement depends on the severity of service conditions.
WARNING
Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting
disassembly:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from either side of the valve.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

Ordering Replacements
When corresponding with your Emerson sales office or Local Business Partner about this equipment, always mention
the valve serial number. It is recommended that complete assemblies are considered for replacements to ensure the
latest version of the product is supplied.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should
not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
