Introduction
Section 1: Introduction
1.1 Scope
This manual is offered as a guide to be used along with locally approved and safe practices
to install, operate, service and maintain the Bettis EHO Actuator. Carefully follow the
instructions in this manual and make sure you install the actuator correctly and according
to your requirements.
1.2 General Information
1.2.1 Overview
The Bettis EHO is a self-contained, quarter-turn, valve actuator that combines proven
technologies from Emerson’s Actuation Technologies. The actuator has been designed for
critical shutdown applications where reliability is crucial. The EHO utilizes a dependable
double-acting actuator for the Fail-safe stroke combined with an integral hydraulic power
pack and electronic control module.
The EHO accepts a wide range of single-phase, three-phase or DC power sources, also solar
panels are available for areas without electrical power. A hydraulic handpump can be used
to stroke the actuator during commissioning or in the event of an emergency power loss.
Electronic modules are contained within an explosion proof, IP68 enclosure and all
electronic components are isolated from the customer connection terminals.
The EHO provides a compact design with actuator and control components that have been
eld proven for decades in critical service applications.
1.2.2 Product Attribute
• Easy installation – Bettis™ EHO actuator is a totally self-contained system and
designed for compactness and adaptable to new or existing valves.
• Bettis™ G-Series hydraulic double-acting or spring-return fail-safe actuator
• Shafer™ hydraulic control technology
• EIM™ electronics and communication technology
• Multiple input power options with either AC or DC
• Local lockable Remote/Local/Ofine switch
• Local open/close/stop switch
• Partial stroke test
• Fast speed of operation to Fail-safe position if required
• Emergency shutdown – independent safety circuits and solenoid valve
• Dual sealed Separate Terminal Chamber, allows installation wiring to be performed
or fuses to be replaced without exposing control components to hostile
environmental conditions.

Section 1: Introduction
Introduction
• Control enclosure is made of low-copper aluminum alloy, powder-coated, salt
resistant also rated for IP68 ingress protection.
• Hydraulic handpump manual override
• Accumulators (optional)
• Solar power (optional)
• Operating pressures up to 3000 psi with standard components
• Easy control over actuator stroking speeds – The stroking speed is controlled
through adjustable hydraulic ow control valves. This enables eld personnel to
easily adjust actuator stroking speed to comply with eld requirements.
1.3 Safety Information
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, void of the warranty. Take special notice of all tags, warning
labels and instructions presented on the actuator. These may provide more specic and
signicant information regarding the actuator than this general manual.
It is the responsibility of the user to ensure proper safety practices are utilized. Always
take necessary precautions and use proper protective equipment when dealing with
compressed gasses, compressed hydraulic uid, pinch points and electricity.
Safety notices are presented in this manual in three forms (Warning, Caution and Note)
as follows:
! WARNING
Alerts user of potential danger; failure to follow the warning notice could result in serious
personal injury or death.
! CAUTION
Identies precautions the user must take to avoid personal injury or equipment damage.
NOTE:
Highlights information critical to the user’s understanding of the Bettis EHO valve actuator
installation or operation.

2.1 Preparation
2.1.1 Delayed Usage
If for any reason the actuator is not to be installed immediately, Bettis recommends the
following procedures. Failure to comply, with recommended procedures, could lead to
actuator malfunction and possibly void the warranty. For storage procedures exceeding
one year, consult Bettis for further recommendations.
As shipped from the factory, the Bettis EHO actuator is an inherently weatherproof unit,
providing that all compartment covers and cable 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 energized.
If the actuator must be stored outside, store it off of the ground at an elevation sufcient
to prevent it from being immersed in water or buried in snow. Check for any unpainted
or exposed metal surfaces and make sure they are protected with a coating of grease to
prevent any corrosion. Cover the actuator to prevent damage from site debris.
2.1.2 Tools and Materials Required
To complete these procedures, you will need the following documentation for the
Bettis EHO Actuator and items indicated in the table below:
• General Arrangement Drawing
• Bill of Material
• Hydraulic System Schematic
• System Wiring Diagram
Table 2. Tools and Material Requirements
Tools and Material Requirements
Primary Power Source for the EHO (check the EHO System Electrical Diagram for requirements)
Supplemental quantity of hydraulic uid, if needed
(See 2.7, Hydraulic Fluid and EHO specication, for required uid type)
Nitrogen Source (if an Accumulator is supplied with the EHO)
Hand Tools: complete complement of open end (SAE and metric) wrenches, screw drivers Philips
and at blade and a set of hex wrenches
Chains and lifting straps that are inspected and certied for the weight of the EHO
Actuator (check shipping weights)
Sealant for all cable and conduit entries (approvable by the National Electric Code or your country
standard and applicable local codes)

Installation
2.2 Valve Preparation
2.2.1 Remove Valve Gearing if so equipped.
2.2.2 If valve is equipped with stops, remove valve stem extension housing. Examine
the valve stops to ensure no foreign material is present that would restrict normal
travel of the valve. Some valves are equipped with inspection ports in the valve
housing for ease in examining the stops.
2.2.3 Check alignment of stem key slot to the position of the valve. Normally with the
valve in the open position, the key slot is in line with the run of the pipeline. With
the valve in the closed position, the key slot should be 90° to the run of the valve.
2.2.4 The EHO Actuator may be mounted to the valve at any time regardless of whether
or not the valve is under pressure.
2.3 Actuator Preparation
2.3.1 Once the EHO Actuator is uncrated and cleaned for installation, check to ensure
there will be no interference with piping or other structure when the actuator is
properly mounted to the valve.
NOTE:
At this point, check to see that when the actuator is mounted to the valve and in its nal
orientation, the outboard end of the power cylinder positioned below the Hydraulic
Reservoir Breather. If this is not possible, contact Bettis for further instructions on piping to
elevate the breather. See Vertical Mounted Actuator 2.4.4.
2.3.2 Check that all mounting materials such as fasteners, adapters, brackets etc. are on
hand and ready for use.
2.3.3 Check the actuator and valve to see that they are in the same relative position,
that is either open or closed. If the actuator has to be moved, use the handpump
provided. For handpump operation, remove the plug in the reservoir and install
the breather (refer to 4.4 Handpump Operation).

2.4 Lifting the EHO Actuator
NOTE:
All Bettis EHO G-Series Considerations
When handling any EHO G-Series, be aware of tubing, accessories, handpump,
accumulators, Pushbutton module and control enclosures. Straps and chains can become
entangled and cause damage to these components. Never use chains on the spring
cartridge as it may warp and cause the actuator not to function correctly or may cause
personal injury.
NOTE:
Do not use hydraulic tubing and electrical cable for lifting.
! CAUTION
Be sure to use appropriately rated crane/hoist and straps/chains to raise and lower
the actuator.
2.4.1 G01X – G2 and All E-Series Actuators
2.4.1.1 Horizontal Pipeline Vertical Stem
The small G-Series and all E-Series actuators mounting on a horizontal
pipeline with a vertical valve stem should be supported under the
“C” bracket and a two-point attachment for balance. A strap may be
attached to the stabilization tab on the spring module to balance the unit
while lifting. The weight of the actuator must be supported at the
“C” bracket, not the stabilization tab. See Figure 1.
Figure 1 G01 – G2 and all E-Series Actuators with Horizontal Pipeline
! CAUTION
Never lift the actuator with a valve attached. Always handle actuator/valve assemblies by
attaching lifting equipment to the valve only.
