5. Transport and storage
5.1 Transport •It is necessary to use solid package during transportation.
•When lifting the electric actuator by hoist, please attach ropes or hook
to enclosure. Do not attach ropes or hooks to handwheel, hand/auto
lever or wiring-box.
•If the electric actuator has been mounted to the gearbox, please
attach ropes or hooks to the gearbox rather than to the electric
actuator for the purpose of lifting by hoist.
•If the electric actuator has been mounted to the valve, please attach
ropes or hooks to the valve rather than to the electric actuator for the
purpose of lifting by hoist.
•Do not stand under the dangling electric actuator.
5.2 storage • Units should be stored in the well ventilated, dry, non-corrosive room.
• Units should be placed on bracket or the dry wooden flooring.
• If necessary, units are covered with dust guard.
• Long-term storage (more than 6 months).
• To avoid corrosion, wipe handwheel shaft, driven shaft, driven sleeve and
mounting surface with anti-rust oil.
• Check the units for rust every 6 months. If there is any rust, please treat
again for rust prevention.
6. Lubrication
-25 ~ +120℃Temperature range
Lithium soap thickened mineral oilPrincipal component
• There are O-rings or lip seal between the main house and its contacting
portion. The main house is fully filled with 00# lithium grease to lubricate the
worm shaft, worm gear, gears, bearings and so on.
• No seal can remain absolutely tight at all time, therefore, it is not unusual to
find a very small amount of weeping around shaft sealing-especially during
long periods of idleness such as long-term storage. Once the equipment
has begun operating, this phenomenon will automatically disappear.
• It is not need to refresh the lubricating grease periodically. If the lubricant is
deficient in quantity or its quality has changed, please infuse the lubricating
grease with the same trademark or the same performance from the
injecting grease hole.
00# gear lubricating grease used by the standard units

7. Installation
7.1 Installing handwheel For easier transport, the handwheels of sizes 9202~9205 are placed
separately, so please mount the handwheel on the manual shaft, before
doing manual operation.
• Handwheel of size 9201 is directly mounted on the product.
• Design of 920 series ensure man power can drive manual operation, no
need to use the force rod.
7.2 Installation to valves or gearboxes
• Apply for the valve stems which can rotate and not lift: Driven sleeve has
two types of structure-one with hole and keyway and one with jaw.
1.Check whether each mating surface of joint flange fits the valve’s.
2.Check whether dimensions of input shaft and key or jaw in the valve or
gearbox fit the electric actuator’s.
3.Clean up grease on the mating surface of joint flange.
4.When connecting with shaft and key, a little of greases is smeared on the
shaft
5.When installing the electric actuator, tighten the screws after ensuring
mating of the joint flange and shaft or jaw is good.
• Without removing joint flange #1, drive sleeve #2 can be directly removed.
Therefore install the drive sleeve to the shaft or jaw of the valve ,and then
connect the electric actuator with the flange of the valve.
• When the valve stem is shaft with key, the valve stem must have a step for
prevent drive sleeve from moving.
• After installation is complete, check and repair the damage coating .
Material performance level of the parts which connect the electric actuator
with the valve or gear is 8.8 class. Yield strength is 628N/mm² .
7.2.1 Plug sleeve connection
•Warning: If electric actuators are installed in the hazardous gas area,
must check whether the ex-proof degree on the nameplate is
appropriate.
• In the hazardous area, it is prohibited that conductive body and thermal
conductor contact with the electric actuator. Except special allowable work,
the units must be cut off power, remove from the hazardous area for repair
or maintenance.
