1. Summary

IMT series un-intrude intelligent multi-turn electric valve actuator (hereinafter referred to as electric actuator) is

used to operate with gate valve, globe valve, diaphragm valve and other valves whose discs make linear movement.

IMT combines with other reducers, so they become a combined multi-turn or quarter-turn electric actuator.

This Operation Manual is prepared for IMT standard type and IMTEx explosion-proof type. For other optional

function, additional instruction will be offered.

2. Major features

2.1 Power supply: 380V, 50Hz, three-phase three-wire sine AC (for other power supply voltage, please let be

informed)

2.4 Ambient humidity: < 90%（at 25℃）

2.5 Altitude: < 1000m

2.6 Short-time duty: Rated time 10、15、30 min （according to the motor’s actual loading）

2.7 Without strong vibration.

2.8 Without strong corrosive material and explosive mixed gas.

2.9 Set-up methods: local selector switches, remote setter (please inform if remote setter is needed)

3. Main structure

Major components of electric actuator:

3.1 Valve special used motor: It conforms to valve’s loading performance and working condition. With a big

start-up torque, small rotational inertia and short-time duty.

3.2 Reducer: it is composed of first-class gear pair and first-class worm gear pair. It is used to transmit and enlarge

the input power of motor. Every seating No. of IMT and IMTEx series has 3-5 kinds of speed ratios for worm gear

pair, and numerous speed ratios for gear pair. Thus, it owns a practical output rotation speed range.

3.3 Output shaft (driving hollow shaft): it is the power-output component of electric actuator. Both jaw type and

valve stem nut type can be provided. The internal thread is usually processed by user. The type of the output shaft is

decided by user when ordering.

3.4 Manual-electric switching handwheel: it is used to switch manual operation between electric operation. It is

semi-automatic, electric-operation priority. Press the handle according to the arrow before manually operating;

gently turn the handwheel until the switching handle is finally rotated at the right place. Manual-electric switching

job is finished and manual operation starts. While it is electrically operated, switch the handle to the electric

operation position and it starts to work electrically.

(Note: it is forbidden to forcefully turn switching handle from manual operation position to

electric operation position, otherwise actuator would be damaged.)

3.5 Manual operation mechanism (handwheel): use handwheel after manual-electric switching is finished. The

handwheel of IMT-04～03(IMT-04～03Ex) is on the top of the actuator, so it directly drives the output shaft during

manual operation. The handwheel of IMT-00～2(IMT～2Ex)、IMT-3～4 is on the side of the actuator, so the

handwheel directly drives output shaft through worm gear pair.

3.6 Torque control mechanism: it controls output torque and protects electric actuator from over-loading and being

jammed.

The working schematic for IMT series output torque: axial force from worm gear acts on Belleville spring, and it

drives torque switch to finish torque control. User is forbidden to adjust the torque value which is locked and

required by user before factory delivery.

3.7 Limit control mechanism: it is used to precisely control valve’s end position and used to feedback valve position

signal. It is composed of middle transmission mechanism, absolute encoder, integrated circuit board, and etc... It

records and processes the rotation turns of output shaft to have valve controlled. Use selector switch and remote

setter to set up actuator after it has been connected with valve, so that a precise limit position and required valve

position feedback are acquired.

3.8 Position indicator: it is used to show valve position, torque and other functions.

3.9 Local selector switch: it is used to set up and operate electric actuator on site.

3.10 Wiring terminal case: it is used for wiring on site. Double-sealing structure is good for actuator’s outdoor

performance.

4. Connection with valve

Preparation before connection:

*Before connection, check if the type and size of the flange of valve and actuator are the same, so as to ensure

the two can connect correctly.

*For the actuator using stem nut, process internal thread of the stem nut to have it connected with valve correctly.

*Clean valve stem and apply grease.

*For rising stem valve, make sure the external part of the valve stem is shorter than the height of the stem cover

of actuator.

*Be care of the mounting position of the actuator against pipe to have enough dismantle space or adjusting space

for actuator.

*There’s no special requirement on actuator’s working position, but motor’s axial level and be vertical to the

selector switch are preferred. This is good for product lubrication, maintenance and check up on site.

4.1 The connection between valve and actuator with stem nut

Put the processed the stem nut into output shaft, and using locking nut to axially fasten it. Sling actuator to make

the internal thread of stem nut to be aligned with valve stem. Manually operate actuator to make the valve open (the

standard rotation direction of stem thread is left, and the output shaft will rotate counterclockwise). Gradually pull

down actuator; as valve stem meshes with stem nut, actuator flange begins to touch valve’s connection surface.

Screw bolt into the flange thread hole and keep the bolt firmly.

To keep stem nut firmly setting in output shaft, user could use cutting tools to damage the meshing fringe

between the upper part of output shaft and locking nut.

Means of dismantling actuator from valve: sling the actuators first; loosen bolts between valve and actuator;

manually operate the actuator to close the valve and the actuator will automatically lift up. Pay attention to sling the

actuator to until to make it separate from valve stem. Make sure the lift is firmly balanced, especially when it is

used for the big-torque actuator.

4.2 Connection between Key/Jaw type actuator and valve

Sling actuator to make its shaft hole to be aligned with valve stem (or to make output shaft’s jaw to be aligned

with stem nut’s jaw); put down actuator and screw bolts into actuator and valve.

When to dismantle actuator, sling it properly first, and then loosen the fixing bolts.

Note: The ring on the actuator is only used to sling the actuator itself, instead of a complete

valve with actuator.

5. Lubrication

5.1 Special used grease has been applied into product before factory delivery. Check the grease at least once a year.

If there is no abnormal situation with it, continue to use.

5.2 If changing grease after maintenance, pay attention to its antioxidation, water resistance, heat-resistance,

corrosion resistance and mechanical stability etc... And also pay attention to the anticompression to ensure actuator

lubrication and high transmission efficiency. (Special-used grease is recommended.)

5.3 When grease is applied into product, do not bring in foreign matters. After grease is filled, it should keep the

filling part to be sealed properly.

5.4 When lubricant (thin oil) is adopted in the electric actuator for special use, the actuator is not filled with oil

before dispatch. User shall inject oil before operation.
