i) The product has 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.

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 and protective film from all name-plates, where

appropriate, before installation on steam or other high temperature applications.

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.

1. Safety information

IM-P167-12-EN-ISS1 CMGT 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.

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 this product may reach

temperatures of 310 °C (590 °F).

This product is 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.

2.1 General description

The M10Hi ISO three-piece body ball valve has a lockable handle and ISO mounting as standard and features

a special ball, which has received a surface hardening. It can be used on applications that use steam and

other industrial fluids for services ranging from vacuum to the higher temperatures and pressures. The

M10Hi ISO has been designed for use as an isolating valve, not a control valve, and can be serviced without

removal from the pipeline.

ISO mounting

The integral ISO body mounting allows the valve to be automated without losing seal integrity, as the body

does not require disassembly. Manual to remote control may therefore be easily accomplished by the ISO

range of Spirax Sarco ball valves.

Available types

M10Hi2 ISO Zinc plated carbon steel body and caps.

M10Hi3 ISO Stainless steel body and caps.

M10Hi4 ISO Complete stainless steel construction.

Note: The nomenclature will be followed with either FB (full bore) or RB (reduced bore).

Standards

This product fully complies with the requirements of the Pressure Equipment Directive (PED) and carries

the mark when so required.

Certification

This product is available with certification to EN 10204 3.1.

Note: All certification / inspection requirements must be stated at the time of order placement.

Note: For further information on this product see Technical Information sheet TI-P167-11-EN-ISS1.

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 Figure 3 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.

Fig. 3 Correct installation for gas service

Do not mount the valve upside down for liquid

service (Figure 2).

Valves should be installed into the pipeline in the fully

closed position. Prior to welding socket and 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.

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 studs (14) and nuts (15), and loosen the four remaining nuts (15). The complete body assembly

can then be removed and any new parts fitted.

Whenever the valve is dismantled, the Geothermal seat and cap 'O' rings (items 16 and 18) must be replaced

before reassembly.

6.3 To replace seats and 'O' rings

-Remove the body as described in Section 6.2.

-With the body removed, remove the seats (5) and 'O' ring (items 16 and 18).

-Fit new seats (5) and 'O' rings (16 and 18), 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 (6virgin PEEK, 21 graphite and 23 stainless steel).

6.5 Reassembly

Reassemble in reverse order to instructions given above. The studs and nuts (14 and 15) should be tightened

to the recommmended torques shown in Table 1 opposite.

After 24 hours in service, retighten body bolts.

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

or protective devices.

6. Maintenance

4. Commissioning

The valve is operated manually by a handle, or automatically by an actuator. 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 control valve, and can be operated fully open or fully closed.
