5.0 GENERAL INFORMATION

5.1 Use

The following instructions are designed to assist in the unpacking,

installation, operation, and maintenance as required for Bray

segmented ball control valves.

Product users and maintenance personnel should thoroughly

review this manual prior to installing, operating, or performing

any maintenance.

In most cases, Bray valves, actuators, and accessories are

designed for speciﬁc applications (e.g. with regard to medium,

pressure and temperature). For this reason, they should not

be used in other applications without ﬁrst contacting the

manufacturer.

WARNING

Before installing the equipment, conﬁrm that it is suitable for the

intended service. The identiﬁcation tags describe the maximum

allowable service conditions for this product. Be sure that the

installation is protected by appropriate pressure control and

safety devices to ensure that acceptable limits are not exceeded.

5.2 Operation

Operation of the valve is done by turning the stem a quarter-turn

(90 degree turn). Clockwise to close, counter-clockwise to open.

CAUTION

Valves with actuators should be checked for actuator/valve

alignment. Misalignment will result in high operational torque,

and cause damage to valve stem and seals.

5.3 Applicability

The following instructions are applicable to the maintenance

and installation of Bray segmented ball control valves. These

instructions cannot claim to cover all details of all possible

product variations, nor can they provide information for every

possible example of installation, operation, or maintenance.

This means that the instructions normally include only the

directions to be followed by qualiﬁed personal using the product

for its deﬁned purpose. If there are any uncertainties in this

respect, particularly in the event of missing product related

information, clariﬁcation must be obtained via the appropriate

Bray sales oce.

Installation, Operation, and Maintenance Manual

contained herein shall not be copied, transferred, conveyed, or displayed in any manner that would

violate its proprietary nature without the express written permission of Bray International, Inc.

5.4 General Precautions

Bray products are often used in critical applications (e.g. under

extremely high pressures with dangerous, toxic, or corrosive

mediums). When performing service, inspection, or repair

operations, always ensure that the valve and the actuator are

depressurized, the valve has been cleaned, and the valve is free

of harmful substances.

In such cases, all personnel operating, inspecting, maintaining,

or repairing Bray products shall wear appropriate Personal

Protection Equipment (PPE), such as: protective clothing, gloves,

safety glasses, steel toes shoes, hard hat, etc.

5.5 Qualiﬁed Personnel

A qualiﬁed person (in terms of this document) is one who has

been authorized by those responsible for the safety of the plant

to perform the necessary work, while recognizing and avoiding

possible dangers.

Qualiﬁcations include appropriate education, training, experience,

and knowledge of relevant standards, speciﬁcations, operating

conditions, and accident prevention.

5.6 Spare Parts

Use only Bray original spare parts.

Recommended spare parts are identiﬁed in the Parts

Identiﬁcation drawing and list for each product model.

Bray cannot accept responsibility for any damages that occur

from using spare parts or fastening materials from other

manufacturers. If Bray products (especially soft good materials)

have been stored for long periods of time, check them for

corrosion or deterioration before putting them into use.

5.7 Service & Repair

To avoid possible injury to personnel or damage to products,

safety terms must be strictly adhered to. Modifying this product,

substituting non-factory parts, or using maintenance procedures

other than those outlined in these Installation, Operation and

Maintenance instructions could drastically aect performance, be

hazardous to personnel and equipment, and may void existing

warranties.

Apart from the operating instructions and the obligatory accident

prevention directives valid in the country of use, all recognized

regulations for safety and good engineering practices must be

followed.

NOTICE

Before products are returned to Bray for repair or service, Bray

must be provided with a certiﬁcate conﬁrming that the product

has been decontaminated and is clean.

6.0 HANDLING REQUIREMENTS

6.1 Packed Valves

Crates: Lifting and handling of the packed valves in crates will be

carried out by a fork lift truck, by means of the appropriate fork

hitches.

Cases: The lifting of packed valves in cases will be carried out in

the lifting points and in the center of gravity position which has

been marked. The transportation of all packed material must be

carried out safely and following the local safety regulations.

NOTICE

When lifting the valve from shipping container, use straps through

valve body. Take care to position lifting straps to avoid damage to

the tubing and mounted accessories.

6.2 Unpacked Valves

Lifting and handling of valves should be carried out by using

appropriate means and observing the carrying limits. Handling

must be carried out on pallets, protecting all machined surfaces

to avoid any damage.

With large bore valves, rigging the load must be carried out by

using the appropriate tools to prevent the valve from falling or

moving during the lifting and handling.

CAUTION

For handling and/or lifting, the lifting equipment (fasteners, hooks,

etc.) must be sized and selected while considering the product

weight indicated in our packing list and/or delivery note.

Lifting and handling must be performed only by qualiﬁed personnel.

Fasteners must be protected by plastic covers in sharp corner areas.

Caution must be taken during handling to avoid this equipment

passing over workers, or over any other place where a possible fall

could cause injury or damage. In all cases, local safety regulations

must be respected.
