NEOTECHA SAPRO® SAMPLING VALVE SV FOR SAMPLING WITH PISTON SYRINGES

InstallatIon and MaIntenance InstructIons

Before installation these instructions must be fully read and understood

1 GENERAL INFORMATION

These installation and maintenance
instructions contain the information necessary
for safe and correct installation and operation
of the valve in the prescribed manner. If any
difficulties are encountered during installation
or operation which cannot be solved with
the aid of the installation and maintenance
instructions, please contact the supplier/
manufacturer for more information.
These installation and maintenance
instructions comply with the relevant applicable
EN safety standards.
When installing the valve, the operator
or the person responsible for the design
oftheinstallation must ensure that applicable
national regulations are complied with.
The manufacturer reserves all rights to make
technical changes and improvements at
anytime.
The use of these installation and maintenance
instructions assumes that the user is qualified
to 'Qualified Personnel' level.
Operating staff must be given appropriate
training in the operating and maintenance
instructions.

1.1 Validity of the installation and
maintenance instructions

These installation and maintenance
instructions are valid for all SAPRO
sampling valves for sampling into piston
syringes, whichhave been manufactured
since 28November 2001 by the Neotecha
AGcompany. The validity is only guaranteed
until the next revision change!

2 SAFETY

Please read these notes carefully.

2.1 General potential danger due to:

a. failure to observe the instructions
b. improper use
c. insufficiently qualified personnel

2.2 Correct use

2.2.1 Area of application

SAPRO sampling valves are valves which
allow a precisely measured sample of
highly corrosive, hot liquids and gases
tobe taken. Aspecial feature of the SV
isthe interchangeable soft seal, which can
be supplied in TFM or Perfluorelastomer,
depending on the medium used, together
with the different body, adaptor and operating
element variants.
The SV is suitable for vertical mountingand
also, subject to certain restrictions,
forhorizontal mounting. When the valve
is installed horizontally, it must always be
ensured that the pipe is filled with sufficient
medium, so that a representative sample can
be taken.
All product-wetted components are
manufactured in PFA/PTFE/TFM materials or in
stainless high-grade steel.
The materials used for components under
pressure are Mat. Nos. 1.4581, 1.0425,

1.4435, 1.4541. Depending on the medium,
other materials, various types of Hastelloy,
forexample, can also be used.

2.2.2 Method of operation

The valve spindle seals against the sampling
adaptor in the soft seat. Before and during
thespindle is lifted it must be ensured that
themedia pressure and temperature are in
themaximum allowable specification according

to the pressure and temperature diagram.
When the spindle is lifted by the plunger of
thepiston syringe, the spindle opens the
outlet and the medium flows into the cylinder
of the piston syringe. The air in the syringe
is compressed, but this does not present
aproblem, as the volume of air concerned
isnot very large.
When the valve spindle is closed, the
SAPRO sampling valve behaves almost
like a continuous section of pipe, because
of thespecially adapted shape of the body.
Verylow friction losses and turbulence
duetothe valve spindle are to be expected.

2.2.4 Usage restrictions

The product-wetted components must be
classified as resistant to the product to be
conveyed. Refer to appropriate literature or
consult the manufacturer or distributor for advice.

2.2.5 Modification prohibition

Mechanical modifications to the valves or the
use of other manufacturers’ parts for repair
purposes are not permissible. Safety is not
guaranteed ifthis requirement is disregarded.
Repair work must only be carried out by the
manufacturer’s trained personnel.

2.2.6 Warning about foreseeable misuse

Valves and their accessories must not be
misused as climbing aids.

2.2.7 Duty to comply with the instructions
foroperation, maintenance and servicing

These operating instructions are part of
thedelivery package and must be kept clean
andmade accessible to the user.

2.3 Sources of danger

2.3.1 Chemical external

The steel/PFA bodies of the DN 65 - 100
valves are made from mechanically processed
steel coated with a 2-part polyester paint.
Thecoating can be attacked externally by
strong solvents, leading to corrosion of
the body. Ifdamage of this nature occurs,
the effects on the environment should be
investigated and thedamage to the coating
made good.

2.3.2 Electrical

If static charges can lead to explosions,
thevalve must be earthed by means of the
earthing accessory.
Alternative: use valves with electrically
conductive linings. Please contact your
supplier!

2.3.3 Thermal

Due to the range of operating temperatures
between -20°C and +200°C, surface
temperatures from -20°C to over +200°C
can be present on thevalve body. Suitable
precautions should be taken at the installation
stage to protect against burns due to high or
freezing temperatures. Insulated gloves should
be worn when using thevalve.
In case of fire, the mechanical strength of the
PFA coatings is no longer guaranteed above
250°C.

2.3.4 Protection against inadvertent opening of the
sampling valve

The SAPRO sampling valve for sampling with
thepiston syringe can only be opened by
the attached piston syringe; under normal
circumstances, it is impossible for the valve to
remain open when the syringe is detached.

2.4 Qualified personnel

This means people who are familiar with
theerection, installation, commissioning,
operation and maintenance of the product and
have appropriate qualifications relating to their
activities and functions, such as, for example:

- Instruction in and duty to comply with all
installation-related, regional and internal
works regulations and requirements.

- Training or instruction in accordance with
theSafety Standards for personal care
and use of appropriate safety equipment
and protective workgear, like, for example,
personal protection equipment (insulated
gloves or similar), suitable for the operating
conditions.

Furthermore, these people must have read and
understood these instructions.
