i) The products have been specifically designed for use on steam, compressed

air, water and other industrial fluids that are in Group 2 of the above mentioned

Pressure Equipment Directive. They can also be used on methane gas, propane

gas, oxygen gas and hydrocarbons which are in Group 1 of the Pressure

Equipment Directive. The products' use on other fluids may be possible but, if

this is contemplated, Spirax Sarco should be contacted to confirm the suitability

of the product for the application being considered.

ii) Check material suitability, pressure and temperature and their maximum and

minimum values. If the maximum operating limits of the product are lower than

those of the system in which it is being fitted, or if malfunction of the product

could result in a dangerous overpressure or overtemperature occurrence, ensure

a safety device is included in the system to prevent such over-limit situations.

iii) Determine the correct installation situation and direction of fluid flow.

iv) Spirax Sarco products are not intended to withstand external stresses that may

be induced by any system to which they are fitted. It is the responsibility of the

installer to consider these stresses and take adequate precautions to minimise

them.

v) Remove protection covers from all connections before installation.

1.2 Access

Ensure safe access and if necessary a safe working platform (suitably guarded)

before attempting to work on the product. Arrange suitable lifting gear if required.

IM-P133-61 ST Issue 1 3

1.3 Lighting

Ensure adequate lighting, particularly where detailed or intricate work is required.

1.4 Hazardous liquids or gases in the pipeline

Consider what is in the pipeline or what may have been in the pipeline at some

previous time. Consider: flammable materials, substances hazardous to health,

extremes of temperature.

1.5 Hazardous environment around the product

Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases,

extremes of temperature, hot surfaces, fire hazard (e.g. during welding), excessive

noise, moving machinery.

1.6 The system

Consider the effect on the complete system of the work proposed. Will any proposed

action (e.g. closing isolation valves, electrical isolation) put any other part of the

system or any personnel at risk?

Dangers might include isolation of vents or protective devices or the rendering

ineffective of controls or alarms. Ensure isolation valves are turned on and off in

a gradual way to avoid system shocks.

1.7 Pressure systems

Ensure that any pressure is isolated and safely vented to atmospheric pressure.

Consider double isolation (double block and bleed) and the locking or labelling of

closed valves. Do not assume that the system has depressurised even when the

pressure gauge indicates zero.

1.8 Temperature

Allow time for temperature to normalise after isolation to avoid danger of burns.

If parts made from PTFE have been subjected to a temperature approaching

260°C (500°F) or higher, they will give off toxic fumes, which if inhaled are likely to

cause temporary discomfort. It is essential for a no smoking role to be enforced

in all areas where PTFE is stored, handled or processed as persons inhaling the

fumes from burning tabacco contaminated with PTFE particles can develop 'polymer

fume fever'.

1.9 Tools and consumables

Before starting work ensure that you have suitable tools and / or consumables

available. Use only genuine Spirax Sarco replacement parts.

1.10 Protective clothing

Consider whether you and/or others in the vicinity require any protective clothing

to protect against the hazards of, for example, chemicals, high / low temperature,

radiation, noise, falling objects, and dangers to eyes and face.

1.11 Permits to work

All work must be carried out or be supervised by a suitably competent person.

Installation and operating personnel should be trained in the correct use of the

product according to the Installation and Maintenance Instructions.

Where a formal 'permit to work' system is in force it must be complied with. Where

there is no such system, it is recommended that a responsible person should know

what work is going on and, where necessary, arrange to have an assistant whose

primary responsibility is safety.

Post 'warning notices' if necessary.

IM-P133-61 ST Issue 14

1.12 Handling

Manual handling of large and /or heavy products may present a risk of injury. Lifting,

pushing, pulling, carrying or supporting a load by bodily force can cause injury

particularly to the back. You are advised to assess the risks taking into account the

task, the individual, the load and the working environment and use the appropriate

handling method depending on the circumstances of the work being done.

1.13 Residual hazards

In normal use the external surface of the product may be very hot. If used at the

maximum permitted operating conditions the surface temperature of these products

may reach temperatures of 300°C (572°F).

These products are not self-draining. Take due care when dismantling or removing

the product from an installation (refer to 'Maintenance instructions').

1.14 Freezing

Provision must be made to protect products which are not self-draining against

frost damage in environments where they may be exposed to temperatures below

freezing point.

1.15 Safety information - Product specific

Hydraulic locking

Ball valves are prone to lock-up when used on certain heating / cooling applications

where both steam and liquid will pass through the valve. This is caused by liquid

trapped in the ball during closure being heated to create a high hydraulic pressure

inside the ball cavity. To prevent this, during manufacture, a minute hole is drilled in

the ball, so, that in the closed position, any excess pressure will be relieved. Spirax

Sarco ball valves for these applications are clearly marked to allow the valve to be

correctly installed, such that, when closed, the hole is facing the steam source.

Cap gaskets

If the 'O' rings have been subjected to a temperature approaching 315°C (599°F)

or higher, they may have decomposed and formed hydrofluric acid. Avoid skin

contact and inhalation of any fumes as the acid can cause skin burns and damage

to the respiratory system.

1.16 Disposal

Unless otherwise stated in the Installation and Maintenance Instructions, this

product is recyclable and no ecological hazard is anticipated with its disposal

providing due care is taken, with the exception of PTFE.

PTFE:

- Can only be disposed of by approved methods, not incineration.

- Keep PTFE waste in a separate container, do not mix it with other rubbish, and

consign it to a landfill site.

1.17 Returning products

Customers and stockists are reminded that under EC Health, Safety and

Environment Law, when returning products to Spirax Sarco they must provide

information on any hazards and the precautions to be taken due to contamination

residues or mechanical damage which may present a health, safety or

environmental risk. This information must be provided in writing including

Health and Safety data sheets relating to any substances identified as hazardous

or potentially hazardous.

Note: Before actioning any installation observe the 'Safety information' in Section 1.

Although the valve has great structural integrity, severe misalignment and/or the pulling effect

of incorrect pipe length will have a detrimental effect on the valve and must be avoided.

Particular attention should be paid to correct pipe alignment such that the inlet pipework and

valve are all on the same axis.

Valves are for on/off applications and may be operated manually.

Wherever practicable, valves should be installed where there is adequate space available so

that they can be conveniently operated and maintained.

Before installing a valve, check to ensure that size, pressure rating, materials of construction,

end connections, etc. are suitable for the service conditions of the particular application.

Care must be taken to ensure that all dirt which may have accumulated in the valve during

storage is removed before installation, maintain cleanliness during installation since the

introduction of dirt can result in damage to the valve seats and operating mechanism.

To minimise the danger of abrasive particles damaging the seats, pipeline strainers should

be ﬁtted upstream of the valves.

Install the valve with the handle in a suitable position. The preferred position is with the spindle

vertical. The valve can be installed in any position for gas service (see Fig. 4 below).

When used on steam services:

1. Fit a trapped drain pocket upstream of the valve.

2. Open valve slowly to prevent the risk of waterhammer damage.

3. Installation

Fig. 4 Correct installation for gas service

Do not mount the valve upside down for

liquid service (Fig. 3).

Valves should be installed into the pipeline

in the fully closed position. Prior to welding

socket an butt weld valves into the pipeline,

it will be necessary to:

1. Dismantle the end caps from the body.

2. Remove the seats and body gasket.

3. Weld each end cap to the pipeline.

4. Replace the seats and body gasket.

5. Reassemble.

Always open valves slowly to avoid system

shocks.

IM-P133-61 ST Issue 110

6. Maintenance

Note: Before actioning any maintenance programme observe

the 'Safety information' in Section 1.

6.1 General information

As with all mechanical devices, regular maintenance is the most efﬁcient means of ensuring

continued operational efﬁciency.

Regular scheduled inspection of all valves is essential especially on valves which are operated

only occasionally.

6.2 General maintenance

Maintenance work can be carried out without removing the complete ball valve from the

pipeline. Remove the two upper bolts and nuts (15 and 16) and loosen the lower two.

The complete body assembly can then be removed and any new parts ﬁtted.

Flanged valves

To proceed with maintenance work, the complete ﬂanged valve requires removal from the

pipeline. Remove the 4 nuts (16), the complete body assembly can now be removed and new

parts ﬁtted.

6.3 To replace seats and body gasket

- Remove the body as described in Section 6.2.

- With the body removed, remove the seats (5) and body gasket (19).

- Fit new seats (5) and body gasket (19), pushing them into the body recesses.

6.4 To replace stem seals

- Remove the body as described in Section 6.2.

- Remove the nuts (9 and 11), and the two belleville washers (8).

- Replace the stem seals (6 and 22).

6.5 Reassembly

Reassemble in reverse order to instructions given above. The securing bolts and nuts (15 and

16) should be tightened to the recommmended torques shown in Table 1 opposite.

After 24 hours in service, retighten body bolts.

4. Commissioning

After installation or maintenance ensure that the system is fully functioning. Carry out tests

on any alarms or protective devices.

5. Operation

The valve is operated manually by a handle. Special care must be taken to ensure that the

movement is made in the correct direction.

The valve can be used as an on/off valve, and can be operated fully open, or fully closed.
