Service Fluid
Characteristics

Conformity to PED/PER on Service Conditions
1.1Application to Dangerous and Harmful Fluid
For servicing the following kinds of fluid, as specified in PED Article 13 Section 1(a), and PER
SCHEDULE 3 Section 3, use of products shall be limited to only those marked Fluid Group 1 on
affixed CE/UKCA labels/nameplates.
Group 1 consisting of substances and mixtures, as defined in points (7) and (8) of Article 2 ofRegulation (EC) No 1272/2008, that are classified as hazardous in accordance with the following
physical or health hazard classes laid down in Parts 2 and 3 of Annex I to that Regulation:(i) unstable explosives(ii) flammable gases(iii) oxidising gases(iv) flammable liquids(v) flammable liquids(vi) flammable solids(vii) self-reactive substances and mixtures(viii) pyrophoric liquids(ix) pyrophoric solids(x) substances and mixtures which in contact with water emit flammable gases(xi) oxidising liquids(xii) oxidising solids(xiii) organic peroxides(xiv) acute oral toxicity(xv) acute dermal toxicity(xvi) acute inhalation toxicity(xvii) specific target organ toxicity - single exposure

For any of the above kinds of fluid, do not use products which are marked
Fluid Group 2.
Also select products in accordance with applicable laws, regulations, safety
standards and engineering standards, where legally, or contractually required to
do so.
1.2Fluid Characteristics Not Recommended for Use of KITZ General Purpose Valves
For the following kinds of fluid, standard trim and sealing materials of KITZ general purpose valves
are not suitable, and resultant fluid leakage may cause danger or harm to servicing personnel andcontaminate the environment. It is recommended to advise us or our authorized distributors fortechnical advice in advance, if you intend to use KITZ general purpose valves to service any one ofthese kinds of fluid.
① Fluid which chemically reacts with air or water (e.g. ammonia)② Fluid which chemically reacts with oil or grease (e.g. oxygen)
KITZ general purpose valves shall not be used for the fluid which chemicallyreacts with pure oxygen or oil to cause spontaneous combustion. Oil-freetreated products marked Fluid Group 1 must be used instead for suchapplications.

Ensure, at all times, that the valve shell, trim and sealing materials are properly selected for the specificservice conditions when you buy and use KITZ general purpose valves. Shell and trim materials of ourindustrial valves are indicated on the nameplates, while detailed material information is provided in our
product catalogs. Improper selection of these materials may cause corrosion of valve internals or
deterioration of material strength, and result in fluid leakage, functional failure and a reduced productlife cycle. Accordingly, upon request, we are ready to provide customers with valve material corrosion
resistance data for their referenced information.
2.1 General
The mechanical strength of main pressure bearing parts of KITZ general purpose valves are designed
and manufactured for safe application to the maximum pressure allowable under the service
temperature specified in the pressure-temperature rating of a relevant valve design standard.

Conformity to PED/PER on Service Conditions
One problem for these valves is that structural design and selection of sealing components are intended
for use in the service conditions, which are rather common, universal and typical in the field. This may
limit application of these valves to some specific service pressures, temperatures and fluid flow
conditions. Users of KITZ general purpose valves are thus recommended to pay a careful attention to
the following remarks when make an off-the-shelf selection of these valves at our distributors.
2.2 Selection of valves provided with non-metallic components
Regardless of the nominal design pressure indicated often on the valve bodies, application of valvesusing non-metallic components such as seats, packing rings and gaskets is often restricted, dependingon actual service conditions, because of inherent properties of such component materials. Typicalexamples are:(1) Valves with PTFE seats and sealing materials(2) Valves with rubber seats and sealing materials
Ensure that on-site process service pressure and temperature should never exceed the range specified in
our product catalogs. The maximum service pressure and temperature are also indicated on CE/UKCA
labels/nameplates.
2.3 Care of Extraordinary Pressure Rise
Ensure selection and used of valves of an appropriate pressure class for services where the valve
internal pressure may extraordinarily rise due to the following causes:(a) Heating(d) Explosion(g) Blocked discharge(b) Exothermic reaction(c) Endothermic reaction(e) Fire(f) Supply fault(h) Blow back from upstream equipment

2.4 Vacuum and Underground Service(1) Vacuum service
Our valves are designed and constructed to have sufficient strength for vacuum service.
However, stem seals of general purpose valves are designed only to resist the valve internal pressure
and leakage is likely to occur through stem seals in case of vacuum service. We recommend use of thevalves specifically designed for vacuum service for this application.
(2) Underground service
Our valves are designed and constructed to have sufficient strength for underground service.
However, besides operation and maintenance difficulty, electric or galvanic corrosion and bacterial
corrosion are inherent problems. Sufficient and adequate care must be taken beforehand to inhibit orprevent such type corrosions occurring on this kind of installation.
2.5 Care of Extreme Temperature Conditions
For the following service environments, valves must be selected with an adequate margin for theservice temperature ranges, to minimize the problems encountered with:(a) Overheating, blockage by scale, distortion and creep caused by high temperature fluid(b) Failure of neighboring accessories or components and distortion caused by high temperatureenvironment(c) Joule Thompson effect and its resultant leakage and destruction caused by low temperature fluid andenvironment(d) Temperature rise caused by heat impact and its resultant material destruction and valve malfunction(e) Material fatigue and destruction caused by repetitive heating.
(f) Valve operational failure caused by frozen lubricant and/or water in low temperature environment(g) In case of hydrostatic piping systems, damage of valves and pipes caused by frozen line water under
rapidly reduced environmental temperature3

Conformity to PED/PER on Service Conditions
2.6 Cavity Pressure Relief Provision
An extraordinary increase of the fluid pressure trapped within the valve body cavity may be caused by
the line fluid temperature or the atmospheric temperature and result in damage of valve internals.
A provision for relief of excessive cavity pressure must be included in customers’ valve specifications,
if there is such a concern. For standard provision of cavity pressure relief for KITZ ball valves, refer tothe details given in our product catalogs.
2.7 Fluid Flow
If types and specifications of valves are not properly selected to satisfy service conditions of line fluid
flow, the following troubles may occur. Selection of proper valves by advising service condition details
to manufactures and distributors in advance is customers’ responsibility for the ultimate performance ofvalves.
It is also important that customers take immediate remedial actions to solve problems, if they occur
on-site.
(a) Pitching, generation of disturbing noise or water-hammering caused by the condition of fluid passage(b) Chattering, hunting or vibration caused by pulsating flow(c) Abrasion, damage or overheating caused by excessive or insufficient flow volume, or extreme change offlow volume(d) Abrasion of valves at flow passing or turbulent area caused by extreme pressure drop or cavitations(e) Erosional wear(f) Vibration or fatigue destruction of valve internal parts caused by high flow velocity(g) Flow obstruction caused by fluid blockage(h) Operation failure or wear caused by fluid residue stuck within the valve interior
2.8 Post-piping Pressure Test
(1) Pneumatic pressure test
Take care of safety issues such as visual inspection of tightened boltings and external leakage at eachstage of pressure increment, when air or nitrogen gas is used as testing media.
Do not over pressurize valves for testing, thereby exceeding the maximum
allowable pressures specified. External leakage of high pressure gas will cause
serious harm and damage to the personnel and test equipment.
(2) Hydrostatic pressure test
When testing, ensure use of clean water containing no solids such as sand or other foreign objects,
which accumulate in piping and may cause trouble to valves and test equipment. Chlorine
concentration in the water shall be less than 100ppm (or less than that legally or contractuallyspecified), when testing austenitic stainless steel and nickel based alloy valves. High chlorine content
in the test media may cause corrosion.
(3) Valve application for installation as piping ends or pressure gates
All valve types shall not be installed for use as piping ends or pressure gates.

Do not install valves for pipe end service, which may cause the external
leakage. In such a case, blank flange or cover shall be securely fitted to thevalve end flange to prevent leakage.

Conformity to PED/PER on Areas, Facilities and the Environment
When valves are installed in facilities and equipment or apparatus for any of the following conditions,
we recommend that proper actions are taken to minimize resultant negative effects such as excessive
load stress, reduced mechanical strength of parts or deterioration of valve materials.
(a) Excessive mechanical or thermal load such as compression or tension caused by piping systems(b) Excessive vibration and dynamic load caused by piping systems(c) Danger of explosion or fire(d) Excessive heat caused by conduction and radiation(e) Excessive heat caused by environmental temperature rise(f) Gaseous or corrosive environment which attacks metallic valve materials(g) Contact with water or high humidity to cause corrosion and damage of valve materials(h) Installation as piping ends
Take proper actions to prevent danger when valves are installed where the following conditions exist.
(a) Questioned durability of valve materials against snow load or wind freezing(b) Mechanical or electrical damage caused by flood(c) Valve operation failure or wear caused by dust(d) Material deterioration caused by radiation(e) Electrical corrosion(f) Bacterial corrosion(g) Accelerated load when valves are installed on mobile equipment or apparatus to affect mechanicalstrength of valves
When installing valves, ensure orientation by properly aligning the correct position, according to each
operation manual, understanding the construction mechanism of valves. Improper installation may
cause problems such as valve malfunction, mechanical damage or deteriorated sealing performance.
The followings are typical examples of the problem.
(a) Reverse installation of check valves against flow direction(b) Installation of check valves on vertical and oblique piping (Note: Lift check valves provided with springs
are acceptable for such piping)(c) Reverse installation of globe valves against flow direction(d) Reverse installation of gate valves provided with vent hole on the disc against high pressure side.
(e) Installation of gate, globe, ball, and butterfly valves with the stem positioned downwards on horizontal
piping.

(f) Functional failure caused by excessive soldering heat in case of soldered copper alloy valves.

It is recommended to ensure proper operation of valves according to KITZ valve operation manuals
and MSS SP-92 “Valve User Guide”, after having checked and confirmed that:(a) Correct power sources are prepared, if applicable.
(b) Valves are facilitated for emergency shutdown, if required.
(c) Corrective actions for operational failure are known to valve operation personnel.

Disassembly and maintenance of products including replacement of trims and sealing components
must be carried out according to the instructions given in KITZ valve operation manuals. We
recommend that users employ our genuine parts or, at a minimum, the parts recommended by us, sothat the design and the ultimate product performance intended by our engineers may not be affected.
When CE/UKCA marked products are disassembled for maintenance, ormodified by purchasers or users, the legitimacy for conformity to PED/PER
requirements becomes invalid, and they are not entitled to claim benefits
granted by PED/PER and its related laws or regulations. Therefore, whenvalves are reassembled after maintenance or modified by purchasers or users
for resale within EU countries, the procedures specified for re-qualification to
PED/PER and its related laws or regulations must be followed. In such a case,
we recommend purchasers or users to contact the notified bodies concerned foradvice and actual re-qualification works (See Note).
KITZ Corporation assumes no liability, nor guarantees the performance,
function and safety of even new products, if purchasers or users disassemble
products for maintenance including replacement of parts, or for modification of
