1.
Install hand wheel (1) onto gear operator shaft and secure with pin (2). (If not already attached)
See Figure 1.
2.
Turn the hand wheel (1) clockwise until in full SHUT position.
3.
Remove 2 screws holding pointer cover plate to center of gear operator to expose bore. Retain
pointer cover plate and screws for reinstallation later.
4.
Assure valve is in full SHUT position, turn valve stem (5) to close disc if necessary.
5.
Assure mounting base of gear operator (3) and the valve top flange (6) are both clean and dry.
6.
Determine desired hand wheel position in reference to the piping system and compare with Fig.
2. There are 2 mounting positions for the gear operator onto the valve and the valve can be
mounted in either direction into the piping system. This will allow hand wheel to be positioned in
any of the 4 quadrants as shown in Fig. 2. Note that all Fire Protection and 10” and 12” size
commercial valves allow for hand wheel positioning in quadrants 1 and 2 only.
7a.
Gear operators with adapter bushing:
Insert adapter bushing (4) into gear operator (3) bore aligning bushing key with desired
keyway. Keyway selection will determine hand wheel orientation position. (Note that Fire
Protection model adapter bushings differ from illustration and only have 1 keyway position).
Align adapter bushing (4) bore with valve stem (5) and slide gear operator assembly onto valve
stem (5) until seated with valve top flange.
7b.
Gear operators without adapter bushing:
Align gear operator (3) bore with valve stem (5) and align with desired keyway. Keyway
selection will determine hand wheel orientation position.
Slide gear operator assembly onto the valve stem (5) until seated with valve top flange.
8.
Tightly secure gear operator (3) to valve top flange (6) using supplied* fasteners (7 & 8).
9.
Reinstall pointer cover plate onto gear operator removed in Step 3 above. Arrow should be aligned
to indicate SHUT position.
10.
Install flag and secure with Allen Screw. (Fire Protection gear operators only).
11.
Rotate hand wheel from SHUT to Full OPEN positions several times to assure proper orientation.
See Stop Adjustment Procedure Section of this instruction booklet if stop alignment adjustment is
necessary.
12.
Proceed with valve installation into piping system.
* A minimum of two fasteners is required, installed in opposite diagonal corners.
NOTES:
For Fire Protection gear operators, it is critical to use only the key supplied with gear operator
in order to conform to UL, FM and ULC specifications.
Connection of gear operator to valve stem varies depending on gear operator model, size and
style. The adapter bushing and key may be different from Figure 1 illustration shown.
