Mounting
1. Clean the lines upstream from the valve. Remove
any debris larger than 0.06" (.015 mm).
2. Alignthevalve’sowindicatorwiththesystem
ow.
3. Mountthevalvesotheactuatorispositionedover
valve.
CAUTION
To prevent condensation from dripping onto the
actuator housing, mount the valve with the actuator
in the upright position or, at most, at a 45° angle. A
45° angle is recommended in steam applications.
4. Sealvalveswithapprovedpipesealant.
5. Usingtwowrenches,securethevalvetothepipe.
Torqueshouldnotexceed75-lbs.(102N•m).
6. Eliminate air from the system to keep the valves
fullofuidduringoperation.
NOTE: Ifthesystemexperienceslargeamountsof
debris,stepsshouldbetakentokeepthe
systemclean.

Action:
Full CW = Valve Closed
Full CCW = Valve Open
CAUTION
Using mineral oil lubricants or other incompatible
substances in system fluids may damage EPDM
rubber seals in valves. Before using any lubricant or
additive in a water or ethylene glycol base, consult
the substance manufacturer for compatibility with
EPDM (Ethylene Propylene Diene Monomer).

CAUTION
To avoid overheating the valve’s actuator in steam
applications, be sure to use standard fiberglass
insulation to insulate the pipe near the valve. Also,
mounting the valve at a 45° angle is recommended
in steam applications.

Maintenance
Noroutinemaintenanceisrequired.Themotorsare
permanentlylubricatedandallinternalgear-train
componentsareoil-impregnated.Carefulinstallation
willalsoensurelongtermreliabilityandperformance.
Adjustments
Theactuatorisfactory-setwiththeOPERATE
selectorswitchintheclockwiseCWposition,and
theactuatorwillrotateclockwisewitha2–10VDC
increasingcontrolsignal.
For Clockwise Rotation
1. LeavetheOPERATEselectorswitchintheCW
position.
2. Depressthegeardisengagementbuonand
rotatethedrivehubfullycounterclockwisetothe
90 mark.
3. Determinewhatpositionthevalveshouldbeat2
VDCinput.
4. Ifneeded,positionthevalvelinkagetothefull
openorclosepositionasdeterminedinstep3.
Thisensuresthatasvoltageincreasesandthe
actuatorrotatesintheclockwisedirection,the
valverotatesintheproperdirection.
5. Securetheactuatorifneeded.
For Counterclockwise Rotation
1. Set the OPERATEselectorswitchintheCCW
position.
2. Depressthegeardisengagementbuonand
rotatethedrivehubfullyclockwisetothe0mark.
3. Determinewhatpositionthevalveshouldbeat2

4. Ifneeded,positionthevalvelinkagetothefull
openorclosepositionasdeterminedinstep3.
Thisensuresthatasvoltageincreasesandthe
actuatorrotatesinthecounterclockwisedirection,
the damper or valve rotates in the proper
direction.
5. Securetheactuatorifneeded.
Fail-Safe Function
Thefail-safeswitchisfactory-setintheO position.

Limit Min./Max. Travel with End Stop Screws
1. Ifdesired,loosentheminimumandmaximum
stopscrewsone-halfturn.
2. Slidethescrewstothedesiredpositions.
3. Tightenthestopscrews(9in-lbs.maximum).
CAUTION
Do not press the gear disengagement button when
the actuator is powered, under load, or driven
against the end stops. Balance the load and remove
power to the actuator BEFORE pressing the button.
