4.2. MECHANICAL INSTALLATION
4.2.1. Mounting & Mechanical Considerations
Every e󰀨ort should be made to properly align the actuator main rod to the valve stem. Any misalignment will decrease the life
of the components within the actuator and may create problems within the application associated with misalignment such as
rod seal leakage.
The Tritex EVA080 can be mounted in any orientation without consideration of performance, but typically the actuator is
mounted vertically, rod end down.
4.2.2. Lubrication Requirements
The actuator is shipped from the factory fully greased and ready for installation. Typical applications will not require
relubrication during the life of the actuator. Exlar recommends using Tribolube 12T, a high performance, extreme-pressure
grease. The unique physical properties of the synthetic base oil provide outstanding protection against wear, rust, corrosion
and high or low-temperature degradation. Tribolube 12T allows for very low starting and running torque values.
4.2.3. Actuator Cover Removal
There are 8 captured bolts on the cover, M8x 1.25, must be tightened to 108 in-lbs., (12.2 Nm). Add 1 in (2.54 mm) clearance
for cover removal and wiring. Always replace cover before applying power in a hazardous location. The clearance distance is
only for cover removal. It is recommended to leave enough room for electrical installation and applicable guidelines followed.
4.2.4. Actuator Mounting Bolts
The actuator is mounted to the valve adapter using 4 bolts, ¼-20 UNC-2B, equally spaced and must be engaged at a minimum
of 0.5 in (12.7 mm) and must be tightened to 62 in-lbs. (7 Nm).
4.2.5. Conduit Entry
The actuator includes 2 conduit entry ports threaded ¾” NPT. Conduit or cable glands should be tightened to 2-3 turns past
nger tight or to 54 in-lbs. (6.1 Nm) of torque. Remove any transit plugs and seal unused entry points with threaded plugs.
NOTE: Power and signal wiring should be routed through di󰀨erent conduit entry points. If power and signal wires are routed
through the same conduit entry point the plastic cap lug should be discarded and replaced with an approved plug and a
minimum of ve threads of engagement.
If the actuator is installed in a hazardous area only appropriately certied conduit, seals, and cable glands should be used. Any
unused entry points must be sealed with certied threaded plugs without the use of an adapter.

CAUTION!
Excessive side load on the actuator output rod will dramatically reduce the life of the actuator and should be avoided. Side
load can result from misalignment or loading that is not in line with the actuator output rod.
CAUTION!
Care should be taken not to exceed the physical travel limits of actuators. Doing so will cause the actuator to end-crash
internally. End crashes can physically damage the roller screw and the internal components of the actuator.
CAUTION!
If the actuator is mounted with the rod end facing up, it must be external protected from exposure to rain. The actuator is
provided with a rod seal which has been tested to NEMA 4X enclosure ratings however long-term wear or misalignment can
cause degradation of the seal and eventually lead to moisture.
4.3 ELECTRICAL INSTALLATION
4.3.1. Electrical Installation
Connections to the actuator are made using the two ¾” NPT entry ports dened in the mechanical installation section (Conduit
Entry 4.2.7). Typically, one port is used for input power wiring while the other entry port is used for control wiring. The terminal
blocks can be accessed by removing the cover (procedure dened in mechanical installation section (Actuator Cover Removal
4.2.5).
WARNING!
For hazardous locations, install wiring and/or cable glands
that are suitable for the environment. Environment examples
include hazardous locations, ingress protection, and
temperature. Failure to use suitable components may results
in personal injury or property damage from re or explosion.
Wiring connections must be made in accordance with the
local, regional, and national codes that apply to the hazardous
area approval. Failure to use suitable components may results in
personal injury or property damage from re or explosion.
4.3.2. Power Source
The power source nominal voltage is 12-24 Vdc. The maximum operating range is 9-32 Vdc. The power source can be a
battery or a DC power supply. If a power supply is used either a regulated or non-regulated supply can be used, if the above
ranges are always maintained. Regulated power supplies typically have built in protections such as over current or overvoltage
and are recommended.
