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

Ensuresafe access and ifnecessaryasafe working platform(suitably guarded)before attempting

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

1. Safety information

IM-P167-16-EN-ISS1 CMGT

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.

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.

2.1 General description

The M10HPi ISO three-piece body ball valve has a lockable handle and ISO mounting as standard. It features

a special floating ball, which has received a surface hardening and a blow-out proof stem. This particular ball

valve has been specially designed for manual isolation of applications using high-pressure gas. The M10HPi

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

M10HPi2 ISO Zinc plated carbon steel body and caps.

M10HPi3 ISO Stainless steel body and caps.

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: 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 2 below).

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

four securing screws (14 and 14a). The complete body assembly can then be removed and any new parts fitted.

Whenever the valve is dismantled, the cap 'O' rings (17) and seat 'O' rings (15 - 2" RB and 1½" FB only) 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), seat 'O' rings (15 - 2" RB and 1½" FB only) and cap 'O'

rings (17).

-Fit new seats (5), seat 'O' rings (15 - 2" RB and 1½" FB only) and cap 'O' rings (17) pushing them into

the body and seat 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 20).

6.5 Reassembly

Reassemble in reverse order to instructions given above. The securing screws (14 and 14a) should be

tightened to the recommended torques shown in Table 1 opposite.

After 24 hours in service, retighten the securing screws.

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

or protective devices.

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.
