Operating and installation instructions
Strainer PN6-160
1.0 General information on operating instructions
These operating instructions provide information on mounting and maintaining the fittings.
Please contact the supplier or the manufacturer in case of problems which cannot be
solved by reference to the operating instructions.
They are binding on the transport, storage, installation, start-up, operation, maintenance
and repair.
The notes and warnings must be observed and adhered to.
- Handling and all work must be carried out by expert personnel or all activities must be
supervised and checked.
It is the owner’s responsibility to define areas of responsibility and competence and to
monitor the personnel.
- In addition, current regional safety requirements must be applied and observed when
taking the fittings out of service as well as when maintaining and repairing them.
The manufacturer reserves the right to introduce technical modifications at any time.
These Operating Instructions comply with the requirements of EU Directives.
2.0 Notes on possible dangers
2.1 Significance of symbols
ATTENTION !
... Warning of general danger.
2.2 Explanatory notes on safety information
In these Operating and Installation Instructions dangers, risks and items of safety
information are highlighted to attract special attention.
Information marked with the above symbol and “ATTENTION ! ” describe practices, a
failure to comply with which can result in serious injury or danger of death for users or third
parties or in material damage to the system or the environment. It is vital to comply with
these practices and to monitor compliance.
All other information not specifically emphasised such as transport, installation, operating
and maintenance instructions as well as technical data (in the operating instructions,
product documentation and on the device itself) must also be complied with to the fullest
extent in order to avoid faults which in turn can cause serious injury to persons or damage
to property.
3.0 Storage and transport
ATTENTION !
- Protect against external force (like impact, vibration, etc.).
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See catalog sheet for weights.
- At -20°C to +65°C.
- The paint is a base coat to protect against corrosion during transportation and storage. Do
not damage paint protection.

4.0 Description
4.1 Scope of applications
Strainers are used for "cleanin flowing mediums“.
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
- Certain media require or preclude the use of special materials.
- The valves are designed for standard operating conditions. If conditions exceed
these requirements, e.g. aggressive or abrasive media, the operator should
state the higher requirements when ordering.
- Valves made from grey cast iron are not authorised for use in systems subject
to TRD 110.
The information complies to the Pressure Equipment Directive 2014/68/EU.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the catalogue sheet to see which materials are used in standard versions.
Please contact the supplier or the manufacturer if you have any questions.
4.2 Operating principles
The medium flows through the strainer screen in the direction shown on the strainer and is
thereby cleaned.

5.0 Installation
5.1 General notes on installation
The following points should be taken into account besides the general principles governing
installation work:
ATTENTION !
- Remove flange covers if present.
- The interior of valve and pipeline must be free from foreign particles.
- Note installation position with reference to flow direction, see mark on valve.
- Steam line systems should be designed to prevent water accumulation.
- Lay pipelines so that damaging transverse, bending and torsional forces are avoided.
- Protect valves from dirt during construction work.
- Connection flanges must mate exactly.
- Connecting bolts for pipe flanges should be mounted preferably from the
counter flange side (hexagon nuts from the valve side).
At DN15-32: If valves should be mounted directly to valves, the upper flange
connecting bolts should be preferably executed with studs and hexagon nuts on
both sides.
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See data sheet for weights.
- Leave sufficient space to remove the screen basket during installation in
pipelines.
- Installation position:
a) The screen basket should never be at the top, otherwise the dirt will
fall back into the pipe.
b) If water hammer is possible due to condensation in steam lines,
never install the trap with the screen basket at the bottom, but install
it so that it is horizontal.
- Centre gaskets between the flanges.
- Install compensators to compensate for thermal expansion of the piping.
- Planners / construction companies or operators are responsible for positioning and
installing products.
- The valves are designed for application, not influenced from weather.
- For application outside or in adverse environments like corrosion-promoting conditions
(sea water, chemical vapours, etc.), special constructions or protective measures are
recommended.

5.2 Installing valves with butt weld ends
Please note that only qualified persons using appropriate equipment and working in
accordance with technical rules are allowed to install fittings by welding.
The responsibility for this lies with the system owner.
Refer to the data sheet for information about the shape of the butt weld ends.
6.0 Putting the valve into operation
ATTENTION !
- Before putting the valve into operation, check material, pressure, temperature
and direction of flow.
- Regional safety instructions must be adhered to.
- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.
- Touching the valve when it is operating at high (> 50°C) or low (< 0°C) media
temperatures can cause injury.
Affix warning notice or protective insulation as appropriate!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- All works has been completed!
- The valve is in the correct position for its function.
- Safety devices have been attached.

Strainer PN6-160
7.0 Care and maintenance
The strainer screens must be cleaned regularly. Maintenance and maintenance-intervals
have to be defined by the operator and depends on the degree of dirt accumulation in the
system.
- If necessary, the strainer can be fitted with an additional start-up filter (e.g. filter with
supporting basket) to start up the system.
- Flush the plant thoroughly before starting it.
- The strainer requires little maintenance.
ATTENTION !
Refer to point 10.0 before opening the strainer.
- Contaminated strainers in suction-lines will result cavitation and damage the
pumps.
- Before reassembling the unit, remember that the bearing surface must be cleaned and a
new gasket (pos. 6) must be inserted.
- Set the strainer cover (pos. 2) in place.
- Tighten the hexagon nuts (pos. 4) evenly crosswise.
- Tightening torque‘s for hexagon nuts / bolts:
