These instructions detail the procedure for installing a Gemini 600 Series electric actuator on a drive-key equipped
Gemini 76, 82, 86, 96 & 89 Series ball valve. Valves may be purchased with the drive-key assembled or may be
retrofitted with a drive-key conversion kit.
76, 82, 86 & 96 Series:
1. Install locator screws in bottom of the electric actuator and tighten with 4mm hex drive
torqued to 30-40 inch lbs. (Figure 1)
2. Place the mounting bracket on actuator so
that locator screws fit into blind holes on bottom of bracket.
Figure 1
3. Check to make sure the bracket is seated
flush against bottom of electric actuator mounting pad. Install bracket mounting screws with
5mm hex drive torqued to 65-75 inch lbs.
4. Check to make sure that valve is in the closed
position and that the stem nut is in the proper
orientation with respect to the drive key (Figure
2). Note: Valve will not engage driver unless
stem nut is in proper orientation.
5. Verify that the actuator is in the closed position. The override handle should be parallel to
the short side of the unit as illustrated.
6. Install the valve into the mounting bracket as
shown in Figure 3. Engagement of the valve
and drive mechanism should require little effort. The top of the valve should lie flat in the
appropriate step so that the bracket straddles
the sides of the hex to resist any rotation.
7. Position the retainer on the underside of the
valve and fasten to the actuator bracket with
the two hex head cap screws. Alternate tightening the screws to ensure balanced tension
and to avoid skewing of the valve retainer strap
relative to the valve body. A gap should remain
between the lower surface of the bracket and
the retainer ‘ears’ when the assembly is complete (Figure 4). Your Gemini actuated valve is
now ready for service.

89 Series:
1. Install locator screws in bottom of the electric actuator and tighten with 4mm hex drive
torqued to 30-40 inch lbs. (Figure 1)
2. Place the mounting bracket on actuator so
that locator screws fit into blind holes on bottom of bracket.
3. Check to make sure the bracket is seated
flush against bottom of electric actuator mounting pad. Install bracket mounting screws with
5mm hex drive torqued to 65-75 inch lbs. .
4. Check to make sure that valve is in the closed
position and that the stem nut is in the proper
orientation with respect to the drive key (Figure
2). Note: Valve will not engage driver unless
stem nut is in proper orientation.
5. Verify that the actuator is in the closed position. The override handle should be parallel to
the short side of the unit as illustrated.

6. Install the valve into the mounting bracket as
shown in Figure 3. Engagement of the valve
and drive mechanism should require little effort. Install valve mounting screws. Your Gemini
actuated valve is now ready for service.
