2000LP valve actuator.
Carefully follow the instructions in this manual and make sure you install the actuator correctly
and according to your requirements.
Safety notices in this manual detail precautions the user must take to reduce the risk of
personal injury and damage to the equipment. The user must read these instructions in their
entirety. Failure to observe these safety notices could result in serious bodily injury, damage to
the equipment, voiding of the warranty, or create operational difculty.
Safety notices are presented as follows:
WARNING:
Alerts user of potential danger; failure to follow the warning notice could result in serious
personal injury or death.
Section 1: Introduction and Safety Information
April 2013

Identies precautions the user must take to avoid personal injury or equipment damage.
NOTE:
Highlights information critical to the user’s understanding of the 2000LP valve actuator
installation or operation.
WARNING:
Read this manual in its entirety before installing, operating, or performing
maintenance on the 2000LP actuator.
WARNING:
Use caution when working on, with, or around valves and actuators. High
pressures, forces, voltages and flammable media can be present.
WARNING:
Failure to follow instructions for proper electrical wiring, storage, setup, and
maintenance may cause serious injury, damage equipment, or void warranty.
Introduction and Safety Information

Section 1: Introduction and Safety Information
April 2013
WARNING:
If the actuator is being installed within a hazardous area, take into account that:
• Improper installation in hazardous areas can cause an explosion.
• Assembly, disassembly and maintenance are only allowed at the actuator
when, at the time of the activity, an explosive mixture is not present.

Section 2: Storage Instructions
If your actuator cannot be installed immediately, the following procedures are to be followed.
This will ensure optimum performance from your 2000LP actuator.
Failure to comply with recommended procedures could lead to actuator malfunction and will
void the warranty.
The 2000LP actuator is an inherently weatherproof unit when shipped from the factory,
providing that all compartment covers and entry plugs remain intact. The actuator should
be immediately stored in a clean, dry warehouse, free from vibration and rapid temperature
changes, until it can be installed and commissioned.
If the actuator must be stored outside, it should be stored off of the ground, at an elevation
sufcient to prevent it from being immersed in water or buried in snow, and covered to prevent
damage from site debris.
If not attached to a valve, the preferred orientation is with the motor and control compartment
horizontal.
Section 2: Storage Instructions
April 2013
If the actuator is mounted on a valve and the valve stem protrudes from the unit, a suitable
stem protector must be installed to prevent drive sleeve corrosion. Stem protectors may be
purchased from your local EIM distributor.
CAUTION:
Condensation or moisture that enters the actuator can damage internal components, which
may ultimately result in failures.
(1) Ensure integrity of gaskets and O-rings.
(2) Seal all conduit openings, whether used or not.
(3) Replace any plastic conduit plugs with pipe plugs appropriate for the application.
(4) Place a packet of dessicant in the control housing to absorb excessive moisture.
For storage procedures exceeding one year, contact your local EIM representative for
recommendations.
Contact information is located on the last page of this manual.

Section 3: Product Data
The EIM 2000LP pneumatic actuator from Emerson is a multi-turn air driven actuator that
is perfect for applications using linear stem, rising stem or rotating stem valves. It can be
powered by air, nitrogen, or natural gas at pressures between 60 and 100 psi. Manual controls
and/or a number of remote pneumatic or electric control options can be provided as shown in
the table below.

There is a ve digit alpha-numeric code used to describe basic actuator features for computer
assisted order entry. This number appears on the actuator nameplate afxed to the actuator
gear housing. The most signicant designators for a sample 2CLG-AF actuator are shown
below.

The 2000LP is based on the proven EIM Series 2000 platform and shares many of its distinctive
features and benets such as direct mounting and handwheel operation during power loss or
emergency situations.
The three most common frame sizes of EIM actuators, the 1000, 2000 and 3000, establish the
foundation for the 2000LP. Subsequently, most major 2000LP mechanical components are
interchangeable with standard EIM electric actuators, which facilitates the acquisition of spare
parts.
The control housing is also a shared EIM electric component, resulting in NEMA 4, 4X and IEC
IP66 product ratings for the 2000LP. Working temperature range is listed at -20 / +150°F (-29 /
+66°C).

Section 4: Lubrication and Maintenance
Section 4: Lubrication and Maintenance
An annual check of the following items should be made of your EIM 2000LP actuator.
1. Check for any external leaks and tighten ttings appropriately and/or replace failed
components.
2. Check for internal component leakage by testing for the presence of air exiting the
exhaust port(s) while the actuator is not moving.
3. Open the control housing to inspect and tighten any loose connections.
4. Visually inspect for any mechanical damage. Replace worn or damaged components.
5. Replace any seals that permit oil leakage or water ingress.
6. Lubrication consistency and quantity needs to be checked only after 3000 cycles
unless the actuator has been leaking oil or making excessive noise. Fill or replace with
recommended uid if required .
Lubrication – EIM actuator gear housings are factory lled with a high quality lubricant carefully
selected to ensure proper performance under specied operating conditions. Refer to EIM JOB
SPEC SHEET to identify the lubricant provided. Normal operation may not require lubricant
replacement.
April 2013
Lubricant level in the gear housing should be maintained at the following quantity. Do not
overfill.
• 1000 and 2000 Frame Sizes
(See “product data” section of this manual for determining frame size)
— Oil: 54 oz (1.54 Liters). Oil is recommended for all drive sleeve speeds over
51RPM.
— Grease: 3.5 lbs (1.58 Kg.). Grease is adequate for drive sleeve speeds under
51RPM.
• 3000 Frame Size
— Oil: 62 oz (1.83 Liters). Grease is not recommended for use in the 3000 Frame
Size

NOTE:
During operation of this actuator, gear housing temperature increase in combination with
variations of outdoor temperature may cause a small pressure build-up within the actuator gear
box. EIM furnishes Pressure Relief Vent Fitting Part No. 83385 to prevent excessive pressure
build-up. Pressure Relief Vent Fitting placement on the actuator can be determined after eld
location and position of the valve have been determined. Select the highest 1/2NPT vent
location of the actuator gear box; remove the ½ NPT plug and replace with Part No. 83385.
