Safety Information (cont.)

1. It is the end user’s responsibility to ensure properly

loaded and/or supported piping to avoid undesired

stresses on the product which may result in

damage to the product, loss of containment, or

loss of functionality and resulting unsafe states or

conditions.

2. It is the end user’s responsibility to correctly

identify end locations and place product in areas

that may contain explosive atmospheres. The

failure of properly following the test, installation,

maintenance and/or disassembly/assembly

instructions may result in a compromised product

which in turn could result in an uncontrolled/

unexpected loss of containment and release of

pressure.

3. It is the end user’s responsibility to take

appropriate actions to ensure that site personnel

who are performing installation, commissioning,

and maintenance have been trained in proper site

procedures for working with and around Baker

Hughes supplied equipment, per Safe Site Work

Practices, are the end user’s responsibility.

4. The failure of properly following the test,

installation, maintenance and/or disassembly/

assembly instructions may result in a

compromised product which in turn could result in

an uncontrolled /unexpected loss of containment

and release of pressure. It is the responsibility of

the person conducting the tasks listed above to

take great care in following such procedures.

5. It is the end user’s responsibility to:

 Recognize and safely contain any leak.

 Ensure proper Personal Protective Equipment

is available and used.

 Follow Proper lifting techniques / equipment /

procedures, per Safe Site Work Practices.

6. Proper Lockout/Tagout of energy sources prior

to maintenance, per Safe Site Work Practices, is

the end user’s responsibility. This includes any

potential control signals or circuits that may have

a remote or automated control function over any

product. Instructions to properly release spring

stored energy included in IOM.

7. After installation or maintenance, it is the end

user’s responsibility to ensure the equipment has

been properly inspected and returned to proper

condition before being returned to service.

1. General

1.1 Scope

The following instructions are designed to guide the user

through the installation and maintenance of the 41005 Series

valves for all sizes and all pressure classes.

1.2 Serial Plate

The serial plate is usually fixed to the side of the actuator

yoke. It indicates, amongst other things, the type of valve,

the pressure class, the material used for the pressurized

chamber and the air supply pressure of the actuator.

1.3 After Sales Service

Baker Hughes offers it clientele an After Sales Service

comprising highly qualified technicians, for the operation,

maintenance and repair of its equipment. To benefit from this

service, contact our local representative or the After Sales

Service whose email address is given at the end of this

document.

1.4 Spare Parts

When carrying out maintenance operations, only

manufacturer’s replacement parts must be used, obtained

through our local representatives or our Spare Parts

Service.

When ordering spare parts, the model and serial numbers

indicated on the manufacturer’s serial plate must be given.

The recommended spare parts are indicated in the parts list

included in this instruction manual on page 35.

1.5 Actuator and Other Accessories

The valve is equipped with an actuator; like all the other

valve accessories, actuators are the subject of special

instructions which provide information on the electric and

pneumatic connections. The instruction manuals to be used

for standard actuators are 19530 for types 87/88 and 31188

for types 51/52/53.

Important

This document contains all the instructions required for the installation, operation and maintenance of the equipment.

Regular maintenance, strict observance of these instructions and the use of manufacturer’s replacement parts will

guarantee optimum operation and reduce maintenance costs.

2. Numbering System

Note: This instruction manual describes all the standard options in the 41005 Series valve. To satisfy the particular

conditions of your application, Baker Hughes may have had to develop a special option which is the subject of an

additional clause to this instruction manual. In this case, the instructions given in the additional clause always take

precedence over the general instructions.

3. Installation

3.1 Cleanness of Piping

Before installing the valve in the line, clean piping and valve

of all foreign material such as welding chips, scale, oil,

grease or dirt. Gasket surfaces must be thoroughly cleaned

to insure leak-free joints.

3.2 Isolating By-Pass Valve

To allow for in-line inspection, maintenance and

removal of the valve without service interruption,

provide a manually operated stop valve on each side

of the control valve and a manually operated throttling valve

in the by-pass line.

3.3 Heat Insulation

In case of heat insulated installation, do not insulate the

valve bonnet and take protection measures related to

personal safety.

3.4 Hydraulic Test and Cleaning of

Lines

During this operation, the control valve must not be used as

an isolating valve.

This means that the valve must always be opened before

carrying out pressure tests in the process line, cleaning of

pipes, etc., otherwise equipment damages or destroying of

seal rings could result.

3.5 Flow Direction

The valve must be installed so that the controlled substance

will flow through the valve in the direction indicated by the

flow arrow located on the body.
