STORAGE/PROTECTION/SELECTION

Storage

When valves are to be stored for some time

before being fitted, storage should be in

theoriginal delivery crates with any waterproof

lining and/or desiccant remaining in place.

Storage should be off the ground in a clean, dry,

indoor area. If storage is for a period exceeding

six months the desiccant bags (if supplied)

should be changed at this interval.

Protection

Valves are delivered with protection according to

customer’s specification, or in accordance with

the Quality Assurance Manual, to protect the

valve seats and closure member from damage.

Wrapping and/or covers should be left in place

until immediately before fitting to the pipe.

Selection

Ensure the valve’s materials of construction

and pressure/temperature limits shown on

the identification plate are suitable for the

process fluid and conditions. If in doubt contact

themanufacturer.

INSTALLATION

WARNING

For safety reasons, it is important to take

thefollowing precautions before you start work on

the valve:

1. Personnel making any adjustments to the

valves should utilize equipment and clothing

normally used to work with the process where

the valve is installed.

2. The line must be depressurized, drained and

vented before installing the valve.

3. Handling and Installation of all valves,

operators and actuators must be carried

out by personnel trained in all aspects of

installation and manual/mechanical handling

techniques.

4. Ensure the valve pressure/temperature

limitations marked on the identification label

are above or equal to service conditions.

Before installation these instructions must be fully read and understood

Installation

1. On-off valves are bi-directional as standard,

unless otherwise stated, and may be fitted

in either direction.

2. Installation may be carried out with stem

displaced through any angle permitted by

the bolting.

3. Spread the flanges to fit the valve easily

(donot use the valve as a crow bar).

4. Remove protective covers from valve faces.

5. Ensure that mating flanges and gaskets are

clean and undamaged.

6. Should there be any possibility of abrasive

particles (weld slag, sand etc.) within the

piping system, this could damage valve

seating areas. The system will need to be

flushed clean.

7. Ensure mating pipe flanges are aligned

correctly, bolting should be easily inserted

through mating flange holes.

8. Fit the valve into pipework ensuring easy

access of the lever/handwheel.

9. Tighten the flange bolts in a diagonal

pattern.

OPERATION AND ROUTINE MAINTENANCE

Scope

These instructions relate to manual and

actuated valves. For special service designs,

typically cryogenic and fugitive emissions see

separate instructions.

Operation

All standard manually operated valves are

‘clockwise to close’. The closed position is

indicated by either the handlever or indicator

arrow being at 90° to the pipe/valve bore axis.

Routine maintenance

No routine maintenance is required other

than periodic inspection to ensure satisfactory

operation and sealing.

Any sign of leakage from the gland packing

should be addressed immediately by

depressurizing the valve and tightening

thegland screws gradually and evenly. If no

further adjustment is possible, or if seat or joint

leakage is suspected, the valve will require a

complete overhaul. This should be carried out

after depressurization and in accordance with

specific maintenance Instructions. Only original

spares should be used.

Spare parts

Valves are identified by a code, which is

stamped on the identification plate, located on

the valve neck. This reference should be quoted

in respect of any after sales queries, spare

parts or repair enquiries/orders.
