the pressure equipment directive
97/23/EC & CE marking
The Pressure Equipment Regulations 1999 (SI 1999/2001) have now been
introduced into United Kingdom law. Valves with a maximum allowable pressure
greater than 0.5 bar are covered by these new Regulations. Valves are
categorised according to their maximum working pressure, size and rising level
of hazard. The level of hazard varies according to the fluid being carried.
Fluids are classified as Group 1, dangerous fluidsor Group 2, all other fluids
including steam. The categories designated are SEP (sound engineering
practice). Valves up to and including 25mm (1“) are designated SEP regardless
of the fluid group. Those identified as having increased hazard are
categorised as, I, II, III or IV. All valves designated as SEP do not bear the
CE mark nor require a Declaration of Conformity. Categories I, II, III or IV
carry the CE mark and require a Declaration of Conformity. Valves classified
from the piping chart wouldnot be included in Category IV.
CE marking & the ATEX Directive 94/9/EC
Concerning equipment and protection systems intended for use in potentially
explosive atmospheres.
This has been implemented in United Kingdom law by the Equipment and
Protective Systems Intended for Use in Potentially Explosive Atmosphere
Regulations 1996(31 1996/192) and amended by The Equipment and Protective
Systems (amendment) Regulations 2001 (SI2001/3766). The regulations apply to
all valves where each valve: a) has its own potential source of ignition. b)
operates in a potentially explosive atmosphere created by:
i) the presence of air/dust mixtures external to the valve.
ii) the presence of gases, vapours, mists released from the valve through
leakage.
The regulations will not apply to a valve without a potential source of
ignition, which operates in a dust free environment and the fluid being
transported is cold, inert gas or nonflammable liquid. The requisite level of
protection for valves not exempt from the regulations is defined as Group II
category 2 and shall bear the following markings: ExII 2 GD X
valve selection
selection, storage & protection
Valves must be properly selected for their intended service conditions.
Provided it is installed correctly and receives adequate preventative
maintenance it should give years of trouble-free service. They must be
compatible with the system design, pressure and temperature requirements and
must be suitable for the fluids that they are intended to carry. Interactions
between metals in the pipe system and the valve must be considered as part of
the valve selection.
Valves should be stored off the ground in a clean, dry, indoor area. Where
desiccant bags are included with the valve these should be changed after a
period of 6 months.
Pegler valves are supplied in cardboard cartons or are bagged as appropriate
and so adequate protection from damage is provided.When Pegler valves are
fitted with pressure equipment or assemblies, suitable protective devices may
be required.
pressure/temperature rating
Valves must be installed in a piping system whose normal pressure and
temperature does not exceed the stated rating of the valve. The maximum
allowable pressure in valves as specified in the standards is for non-shock
conditions. Water hammer and impact should also be avoided.
If system testing will subject the valve to pressures in excess of the working
pressure rating, this should be within the “shell test pressure for the body”
to a maximum of 1.5 times the PN rating and conducted with the valve fully
opened.
It may be hazardous to use these valves outside of their specified pressure
and temperature limitations and also when not used for the correct
application.
location/end-of-line service
To ensure ease of operation, adjustment, maintenance and repair, valve siting
should be decided during the system design phase. To prevent imposing strain
on the valve seat,
pipe work and valves they must be adequately supported.
The 1072, 1070/125, 1065 and 1068 Gate valves are suitable for end of line
service but we strongly recommend the fitting of a blanking plug to the
downstream end of the valve. Pegler Ball, Globe, Check, Flanged and Lever Gate
valves are not suitable for end-of-line service.
Installation
health & safety
Before starting work on any installation a risk assessment must be made to
consider the possibility of operational limits being exceeded and reduction or
elimination of any
potential hazards.
- Protective clothing and safety equipment must be utilised as appropriate to the hazard presented by the nature of the process to which the valve is being installed or maintained.
- Before installing or removing a valve the pipeline circulating pumps (when fitted) must be turned off. The pipeline must be depressurised, drained and vented. Valves must be fully opened to ensure release of any pipeline or valve pressure.
- Fitters must be trained in manual and mechanical handling to enable them to safely lift and install Pegler valves.
- The valve selected must be suitable for the required service conditions. The pressure and temperature limitations are indicated on the valve nameplate, body or data plate. These must not be exceeded.
- Valve seats, seals and internal components can be damaged by system debris. Protective devices may need to be fitted and system flushing may be required.
- Any flushing fluid used to clean the pipeline must not cause any damage to the valve and its components.
- Pegler valves must not be misused by lifting them by their hand wheels, levers or stems.
- Pegler valves are not suitable for fatigue loading, creep conditions, fire testing, fire hazard environment, corrosive or erosive service, or for carrying fluids containing abrasive solids. There is no allowance for corrosion in the design of these valves. Designs for this valve do not allow for decomposition of unstable fluids and must not be used where this could occur.
- Pegler valves are not designed to withstand the effects of fire, wind, earthquakes and traffic.
- All Health and Safety Rules must be followed when installing and maintaining valves.
installation
Unpack the valve and check that the flow paths and valve threads are clean and
free from debris. Check the body markings and nameplate to ensure that the
correct valve has been selected for installation.
Gate valves and Globe valves may be fixed in “Vertical pipe work with stem
horizontal” or “Horizontal pipe work with stem vertical and upright”.
Globevalves are marked with a directional flow arrow on the body. The valve
willfunction correctly providing it is fittedso that the fluid transported
follows the indicated flow direction.
Make sure that a gate valve is fully closed during installation. Fitting a
gate valve in the open position may cause twisting and the gate and seating
may not mate properly. The valve should be operated from fully open to fully
closed to test that it has been correctly installed.
The valve should not be installed in horizontal pipe work with stem horizontal
because full closure may be impeded by an accumulation of system debris.
Pegler Valves are
manufactured to exacting standards and, therefore, should not be subjected to
misuse. The following should be avoided: careless handling of the valve
(Valves should not be lifted using the hand wheel, lever or the stem). dirt
and debris entering the valve through the end ports. *Excessive force during
assembly and hand wheel operation. Ball valves may be fixed in any
orientation, always leaving enough space for the 90° operation of the lever
handle. Horizontal and vertical pattern check valves may be fitted in
horizontal pipe work with the cap upper most and vertically with the flow in
an upwards direction. The valve is marked with a directional flow arrow on the
body. The valve will function correctly providing it is fitted so that the
fluid transported follows the indicated flow direction. Check valves having 6
diameters of straight length of pipe upstream and 3 diameters downstream are
suitable for velocities of 3 metres per second. If the valve is situated such
that non uniform or pulsating flow enters the valve, e.g. the valve is close
to reciprocating pumps, then the velocity should not exceed 2 metres per
second. Use suitable hangers close to both ends of the valve in order to
remove stresses transmitted by the pipe. Confirm that the pipe threading
length is correct to avoid excessive penetration of the pipe into the valve
that would otherwise cause damage. Care should be taken to apply jointing
compound to the pipe only and not inthe valve threads. Surplus compound will
then be forced outwards and will not enter the valve. Over use of compound can
lead to valve failure on the body ends. Threads should be engaged correctly
when tightening the valve onto the pipe. The wrench should always be fitted on
the body end adjacent to the joint being made. Severe damage can occur to
stems, valves and seats by the use of hand wheels or levers larger than those
originally supplied by the manufacturer, and by wheel keys. Anyelectrical
component e.g. actuators, limit switches must be explosion proof and comply
with the ATEX Directive and Standards as listed in BS EN 1127-1 clause 6.4.5.
operation
gate valves
To open – an anti-clockwise rotation of the hand wheel will open the valve.
When it will go no further return the hand wheel clockwise 1/2 turn. To close
the valve a clockwise rotation of the hand wheel will close the valve.
Closure will be confirmed when the handle can be turned no further.
caution: Service applications with extremes of temperature may cause the
wedge to become tight in the valve. The valve may be become stiff to operate
in these circumstances. Suitable hand protection should be worn when
operating valves used in extreme temperature applications. The valve should
only be used in the fully open or fully closed position. Gate valves are not
suitable for regulating and throttling service.
globe valves
To open – an anti-clockwise rotation of the hand wheel will open the valve.
When it will go no further return the hand wheel clockwise 1/2 turn. To close
the valve a clockwise rotation of the hand wheel will close the valve.
Closure will be confirmed when the handle can be turned no further.
caution: Suitable hand protection should be worn when operating valves
used in extreme temperature applications. Globe valves are suitable for
regulating and throttling service.
check valves
The Horizontal/vertical pattern check valves operate according to the flow
within the pipeline and there is no external method of operation.
ball valves
PB LEVER HANDLE To open – turn the lever 90° so that it is in line with
the pipe run in which it is installed. To close – turn the lever 90° so that
it is across the line of the pipe in which it is installed. Full opening and
closing is completed when a full 90° is achieved and the lever is firmly set
against the stop on the valve body.
PB T Models have lockable handles for use in both open and closed
positions. In the fully open position the T handle is in line with the pipe
work. To lock the valve in the open position a hexagon key of the appropriate
size can be used to remove the securing screw. The T handle can then be lifted
from the valve. This should then be rotated through 180° and refitted on to
the valve spindle ensuring the handle slot engages on to the body lug. Insert
the securing screw and re-tighten with the hexagon key.
PB EL models are fitted with an extended spindle mechanism that lifts the
lever away from the body and is particularly useful when pipe insulation is
being used. This version is only available with a standard lever handle.
Caution: Service applications with extremes of temperature may cause the ball
to become tight in the valve. The valve may be become stiff to operate in
these circumstances. Suitable hand protection should be worn when operating
valves used in extreme temperature applications. The valve should only be used
in the fully open or fully closed position. Ball valves are not suitable for
regulating or throttling applications.
maintenance
A regular maintenance program is the most efficient method of ensuring longer term operational efficiency of the selected valve. Such a program would need to include a risk assessment and a planned procedure of how the maintenance will be carried out. The possibility of operational limits being exceeded and the potential hazards ensuing must be considered as part of this assessment. This should be implemented to include visual checks on the valve’s condition and any development of unforeseen conditions, which could lead to failure. The correct fitting tools and equipment should be used for valve maintenance work. Separate means of draining the pipe work must be provided when carrying out any maintenance to valves. Where there may be any system debris this should be collected and/or filtered by installation of the appropriate protective device.
gland adjustment
The gland may need adjustment during installation and then periodically
thereafter to maintain a stem gland seal.
note:
it is recommended that within the 1st year the gland be inspected at 3 monthly
intervals to check for gland leakage.
gland replacement
Under normal working conditions Pegler gate and globe valves do not normally
require any maintenance, however, in the event of maintenance being necessary,
the following
procedure should be followed: Before starting work, de-pressurise the system,
turn off any circulating pumps. Slacken the hand wheel nut and remove the nut,
nameplate and
hand wheel. Remove the gland nut and gland ring. Using a suitable tool, lift
out the existing packing and makesure the stem and stuffing box are clean &
free from debris. Care must be taken not to damage the valve stem.
Fit a replacement Pegler packing gland into the stuffing box and push down
firmly.
Re-assemble the gland ring and gland nut.
Re-attach the handwheel, nameplate and nut.
Tighten the gland nut and confirmstem resistance while operating the valve.
Once line pressure is reestablished a check for leak tightness should be made,
further adjust the gland nut as required necessary to achieve a satisfactory
seal.
Note: maintenance Permanent removal of the gland nut and /or the Data.
Plate will invalidate the CE compliance of this valve. Pegler Ball valves and
Check valves are generally NOT suitable for maintenance.
According to valve type, gland packing and valve discs may be replaced. Valves
within the scope f the ATEX Directive with a protective level defined as
Group II category 2 will operate in Zone 1 (gases/vapours) or Zone 21 (dust)
designated in BS1127-1 Explosion prevention and protection. Tools are either
“single spark” e.g. screwdriver, spanner, impact screwdriver or “shower of
sparks” e.g. sawing or rinding. Only steel “single spark” tools are permitted
in Zones 1 & 21. Tools causing showers of sparks are only permissible if: a)
no hazardous explosive atmosphere is present. b) dust deposits have been
removed and no dust cloud is present. The use of tools on equipment in Zones 1
and 21 should be subject to a “permit to work” system. 1029 renewable valve
disc replacement Before starting work de-pressurise the system, turn off any
circulating
pumps, and ensure the valve is empty of fluid. Using a suitable wrench remove
the complete bonnet assembly from the valve. Care should be taken to ensure
the pipework is
held securely during this process so that there is no distortion to the valve
threads. Any damage to the threads could lead to valve failure. Slacken and
remove disc nut and disc. Assess damage to valve seat replacing the whole
valve if necessary.
The valve disc can be replaced with an equivalent size disc and type as
appropriate. Re-attach a replacement disc and disc nut. Re-assemble the bonnet
in to the valve body, checking for damage. Ensure the valve bonnet is joined
securely to body and will not leak.
note:
the 1029 Globe valves have nonmetallic PTFE valve discs. installation,
operating & maintenance instructions are available from sales office
Pegler recommended spares must be used. Refer to Pegler Technical Department
for further information. product life span When a valve is properly selected
for its service conditions it should give years of trouble-free service
provided it Is installed correctly and receives adequate preventative
maintenance. By not considering the compatibility of the system design and the
pressure and temperature requirements the life expectancy of the valves can be
adversely affected and valve failure may occur. The nature of the fluid being
carried through the valve could also affect the valve performance as this
could lead to premature valve failure. There may also be interactions between
metals in the pipe system and the valve which need to be considered.
Appropriate flushing and cleaning of the pIpe work Installation should take
place when commissioning the system as this would help extend the valve life.
