i) The products have been specifically designed for use on clean/pure steam

and other high purity applications that are in Group 2 of the above mentioned

Pressure Equipment Directive. They can also be used on Fluids which are

included 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 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.

1.3 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.

IM-P173-01-EN-ISS1 CMGT4

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.

IM-P173-01-EN-ISS1 CMGT 5

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 200 °C (392 °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 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.

1.16 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

2. General product information

2.1 General description

The M70i and M80i 316L stainless steel, three-piece body ball valves have ISO mounting

as standard. They have been designed in accordance with ASME BPE for use on

applications like liquids and gases utility and process support applications, such as clean

steam*. These valves should be used as isolation valves, not a control valves.

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 tting a BVA 300 series pneumatic actuator available

from Spirax Sarco. For further details contact Spirax Sarco.

Standards

These products fully comply with the requirements of the European Pressure Equipment

Directive (PED) and carry the mark when so required.

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 and outlet

pipework and valve are all on the same axis.

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

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

stem vertical and upwards. The valve can be installed in any position for gas service (see

Figure 4 opposite).

When used on steam services:

(The alternative with Cavity filler is not recommended when used on steam service)

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

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

Do not mount the valve upside down for liquid service (Figure 3).

3. Installation

Fig. 3 Incorrect installation for liquid service

Valves should be installed into the pipeline in the fully closed position.

Always open valves slowly to avoid system shocks.
