1 GENERAL
1.1 Scope of the manual
This instruction manual contains important information
regarding the installation, operation and maintenance of
Metso N1 series actuators. Please read these instructions
carefully and save them for future reference.
The manual can be changed or revised without any prior
notice. Any changes in product’s specification, structure,
and/or any components may not result immediate revised
version of the manual.
1.2 Structure and operation
The N1 series actuators are pneumatic quarter turn cylinder
actuators designed for control and shut-off service. Design
is modular and enables an ideal configuration of pneumatic, central block and spring modules. Ductile cast iron
center body, fabricated carbon steel pneumatic module
and spring module provides rugged actuator construction.
The spring provides the required safety function; the valve
either opens or closes if the air supply is interrupted.
The mounting face dimensions of the N1 actuator comply
with the ISO 5211 standard.
The N1_E_C is spring to close type actuator. The yoke of the
actuator, when operated by the spring, rotates clockwise as
seen from the pointer cover side. The piston then moves
towards the frame side of the cylinder. The two keyways in
the yoke are positioned at an angle of 90° to each other,
making it possible to change the position of the actuator in
relation to the valve, see Fig. 1.
Fig. 2 Operating principle of the N1_E_A actuator.
The N1_D is a double acting actuator. The linkage mechanism converts linear motion (provided by an air supply and
piston) to rotary motion. The yoke of the actuator rotates
clockwise (close) when cylinder supply is in rear port and
counter clockwise (open) when cylinder supply is in front
port, see Fig. 3.
Fig. 1 Operating principle of the N1_E_C actuator
The N1_E_A is spring to open type actuator. The yoke of the
actuator, operated by the spring, rotates counter clockwise
as seen from the pointer cover side. The piston then moves
towards the frame side of the cylinder. The two keyways in
the secondary shaft (yoke) are positioned at an angle of 90°
to each other, making it possible to change the position of
the actuator in relation to the valve, see Fig. 2.

3 MOUNTING AND DEMOUNTING
3.1 Actuator gas supply
Dry compressed air, nitrogen or natural gas (sweet) can be
used as supply medium, no oil spraying is needed. The air
supply connections are presented in the dimensional drawings in Chapter 9. The maximum supply pressure is depending the selected model.
3.2 Installation information
Before installation please take care of the safety precautions mentioned in the Section 1.7.
Ensure that the actuator will not be exposed to pressure in
excess to the maximum rating as indicated on the actuator
nameplate or technical documents.
Ensure that throughout the installation that there are no
leaks of the supply media.
The maximum operating temperature for the actuator
depends on individual build of actuator. Refer nameplate
for operating temperature range.
Ensure that the maximum operating temperature as indicated on the nameplate is not exceeded during operation,
transportation or storage of the actuator.
The environment and surrounding should not affect or limit
the operational safety of the product.
Ensure the product is protected against impact, vibration or
any kind of movement during operation, transportation
and storage.
Product should not be installed in hazardous area that is
not compatible with the gas group and temperate class
indicated on the nameplate.
N1 series actuators can be mounted on valve in any desired
position. However it is recommended to align the centerline of the pneumatic cylinder module along the pipeline.
Ensure proper tightening of fasteners and mounting accessories to avoid loosening during operation.
All the tubing, fitting and actuation media should be free
from contamination and filtered to the desired level. Quality of media should be as per ISO 8573-1 [5:3:4]. For additional information consult Metso.
Ensure proper adjustments of the stopper bolt to desired
opening and closing of the valve.
Once proper installation is done, check for smooth continuous operation. If undesired operation occurs, check for correct pressure and volume flow.
NOTE:
Flow may be restricted by undersize tubing or fitting.
These may throttle the flow resulting in reduce pressure or
volume causing intermittent or undesired movement.
3.3 Mounting the actuator on the valve
CAUTION:
Be aware of the cutting movement of the valve!
Install the actuator so that the shaft of the valve or any
other device to be actuated goes into the shaft bore of the
actuator. If the bore is larger than the shaft diameter, use a
keyed shaft adapter, sleeve or bushing. There are two key
way slots in the shaft bore of the actuator at an angle of 90°.
These allow the installation position of the actuator to be
changed in relation to the valve. Metso valves have a bevel
at the end of their shafts to facilitate installation.
Fig. 6 Ways to install the actuator
The installation position can be selected freely, but Metso
recommends installation of spring return version with the
pneumatic cylinder pointing towards the ground. Double
acting version can be installed any position. The actuator is
thus best protected against damage due to supply air
impurities or water. When the installation position of the
actuator is altered, the arrow indicating the operating direction must be turned to correspond with the actual operation of the valve.
When necessary, lubricate the actuator bore and collar with
grease or anti-corrosive agent to prevent it from jamming
due to rust.
The actuator must not be allowed to come in contact with
the pipework, because the vibrations may damage it or
cause unsatisfactory operation.
In some cases, e.g. when using large actuators or with
extensive pipework vibrations, the actuator should be supported. Consult Metso for instructions.
If the actuator is used with devices other than Metso valves,
any additional parts attached to the actuator must be properly protected.
3.4 Operating directions
A sticker on the actuator cylinder indicates the spring
action direction.
NOTE:
Separate instructions are available for adjusting the close
limit of metal-seated butterly valves. Refer to the installation, operating and maintenance instructions of the valve.

4 MAINTENANCE
4.1 Maintenance general
CAUTION:
Observe the safety precautions mentioned in Section
1.7 before maintenance!
Although Metso’s Neles actuators are designed to work
under severe conditions, proper preventative maintenance
Can significantly help to prevent unplanned downtime and
in real terms reduce the total cost of ownership. Metso recommends inspecting the actuators at least every five (5)
years. The inspection and maintenance interval depend on
the actual application and process condition. The inspection and maintenance intervals can be specified together
with your local Metso experts.
During this periodic inspection the parts detailed in the
Spare Part Set should be replaced. Time in storage should
be included in the inspection interval.
If maintenance assistance is required, please contact your
local Metso office. The part numbers in parentheses () in the
text refer to the exploded view and to the parts list in Section 8, unless otherwise stated.
This procedure is applicable with the understanding that all
pneumatic pressure has been removed from the actuator.
Remove all piping and mounted accessories that will interfere with the module that are to be worked on.
When removing seals from seal grooves; use a commercial
seal removing tool or a small screwdriver with sharp corners
rounded off.
Use a non-hardening thread sealant on all pipe threads.
CAUTION:
Apply the thread sealant as per the manufacturer’s
instructions.

3.4.3 Demounting the actuator from the
valve
CAUTION:
Depressurise the actuator before starting demounting!
The actuator must be de-pressurized and the supply air disconnected. Unscrew the actuator-side screws of
the bracket and pull the actuator off the valve shaft. This is
best done lifting the actuator from lifting lugs by crane.
Note the mutual positioning of the valve and the actuator
to ensure correct functioning after reassembly.
All parts should be thoroughly inspected for excessive wear,
stress cracking and pitting. Attention should be directed to
threads, sealing surfaces and areas that will subjected to
sliding and rotating motion.
Actuator parts that reflect any of the above listed characteristics should be replaced with new parts.
Metso recommends that disassembly of the actuator modules should be done in a clean area on a workbench.
After reassembly, the actuator needs to be stroke for several
times to ensure the desired function and safety.
If you remove the stop screw, adjust the limits after lubrication or grease filling!
Before doing maintenance, check actuator for leakage at
inlet, outlet and cover.
8 6 N1 70 en
For single acting actuator if port B is connected then check air leakage from exhaust port.
For double acting actuator if port B is connected then check air leakage from exhaust port.
