TORQUE OUTPUT

MAINTENANCE

Gemini A500 Series Pneumatic Actuators are designed to be maintenance free and normally are replaced

vs. repaired.

Double-Acting Models: For double-acting models, rebuilding of the actuator by our Factory Authorized

Service Center may enable the actuator to be returned to service depending on the duty cycle the actuator

has seen. The cost to rebuild the actuator is generally 50% of the cost of a new actuator. For details on this

service please contact us. Additionally, for those customer desiring to replace 0-rings, gasket(s) and lubri-

cant, we offer o-ring kits which contain these genuine factory components.

Spring-Return Models: For the A500 Series spring-return models, rebuilding of the actuator by our Fac-

tory Authorized Service Center may enable the actuator to be returned to service depending on the duty

cycle the actuator has seen. The cost to rebuild the actuator is generally 50% of the cost of a new actuator.

For details on this service please contact us. O-rings kits are not available for theA500 Series Spring Return

models.

Torque Output - in. - lbs.*

CAUTION: Care must be taken to assure the output torque of theA500 SeriesActuator selected is adequate

toturn thevalve ordevice tobe operated. Note:Does notapply formounting ofGemini Valves toA500 Series

Actuators. Gemini Valve offers a selection chart for your convenience. See our literature for details. Note

also; special sizing considerations should be given when a valve is handling suspended solids, abrasives,

dirty media, oxygen and dry gasses.

ACTUATOR TO VALVE MOUNTING INSTRUCTIONS

76, 82, 86 & 96 SERIES VALVES

Theseinstructions detailthe procedurefor installinga GeminiA500Series actuatoron adrive-keyequipped Gemini

76,82, 86& 96Series ballvalve. Valvesmay bepurchased withthe drive-keyassembled ormay beretrofitted with

a drive-key conversion kit.

Instructions:

Assemble Bracket toActuator

1. Positionthe actuator uprightwith

driver and the A & B ports oriented

as shown in Figure 1.

2. With the counter sunk holes ex-

posed, position the bracket to

achieve an inline or cross mounted

actuator orientation as described

below. Table 1 lists the valve condi-

tion at rest with respect to the Ac-

tuator Model # (See actuator name-

plate to determine model number

a. Inline- (standard mounting for

mostactuators) The longaxisof the

actuator is in-line with the piping.

Thebracket should beoriented per-

pendicular to the actuator body.

(See Figure 2)

b.Cross mounted- the long axis of

the actuator is perpendicular to the

piping. The bracket should be

mounted parallel to the actuator

body. (See Figure 3)

3. Install the 4 hex flat socket head

mounting screws to (60 inches lbs. for

A510 and 75 inch lbs. for A520 actuators)

securebracket tothe actuatorbody.

Important:Toensurepositive fasten-

ing mounting screws and bracket

counter sunk holes must be clean

and dry. Figure 3

IMPORTANTNotethe redOPEN/

SHUTindicator mountedontop of

theactuator shaftand theposition

ofthe ballin thevalve. Theactua-

tor should be mounted such that

the red indicator is in-line with the

valve body when the ball is in the

openposition,or acrossthe valve

bodywhen theballis inthe closed

position.

1. Rotate the valve stem so that it

is in the corresponding closed or

open position with regards to the

actuator. The drive key on the

valve should be perpendicular to

valvebodywhenvalveisopenand

parallel when in the closed posi-

tion.

2. Confirm proper position of the

locator screws on the bottom of

thebracket basedon the sizeand

seriesof thevalve beingmounted

as Listed in Table 2.

3. Place the actuator, with the

bracket attached, atop the valve

so that the 12 point socket en-

gages the stem nut, the shaft

notch engages the drive-key and

locator screws straddle the valve

body hex (see Figure 4). If the lo-

catorscrewsdonotspan thevalve

properly (i.e. interfere with eye-

browsordonot engagevalve) turn

valve 180 degrees.

4. Positionthevalveretainingstrap

over the valve and align with

bracket holes. Secure strap with

two hex head cap screws. Alter-

nate tightening the strap bolts to

obtain even tension on the strap

andtoavoid skewing. Donotover

tighten. A gap should remain be-

tween strap and bracket when

ACTUATOR TO VALVE MOUNTING INSTRUCTIONS

89 SERIES VALVES

These instructions detail the procedure for installing a GeminiA500 Series actuator on a drive-key equipped

Gemini 89 Series ball valve.

Instructions:

securebracket tothe actuatorbody.

Important: To ensure positive fas-

tening, mounting screws and
