Alwa Sampling Valve

Product specification sheet

Application

Sampling valve for chemical and microbiological parameters in
drinking, bathing and swimming pool water.

Suppliers of drinking water for public use have to commission an
annual investigations of water to prevent Legionella occurrence
according German regulations TrinwV §§4, 14 (6) and 19 (7) and
Appendix 4.

There are defined sampling locations for the determination of
drinking water system contamination by Legionella.

Special Features

• May be retrofitted to any Alwa F/KFR/R fittings from DN15 to
DN80

• Valve body and outlet bend may be rotated through 360° and
hence may be aligned in any direction

• Outlet volume may be regulated and the valve may be shut off
by means of an allen key

• Certificate regarding suitability for sampling in accordance
with VDI 6023 and German water regulations

• Correct sampling procedure possible

• A sampling valve for all types of sampling

• All parameters to be determined may be taken at one point

• Horizontal and vertical mounting possible

• Sampling equipment is simple to operate and may be flame
sterilised

• Stable, long, stainless steel outlet bend generates a straight
water jet

• Valve body and parts in contact with the medium in red
bronze

• High quality, hygienic EPDM seat seal with German health
ministry plastics and water approval

Range of Application

Medium The sampling valve was developed for usage in cold

or hot drinking water systems, swimming pools and
bathing water systems.

The sampling valve should be used for investigation of Legionella
contamination at determined locations in potable water systems.

Method of Operation

Operators who supply drinking water to the public must commis­sion tests for legionella once a year.

There are often no suitable sampling valves in the drinking water
system, so that sampling takes an unnecessarily long time and

G

cannot always be carried out correctly.

The sampling valve may be fitted horizontally or vertically on any
Alwa F/KFR/R fitting with a drain plug.

A flame is applied around the fitting to disinfect the stainless steel
outlet pipe. The sampling valve can be regulated and the flow
volume regulated with an allen spanner.

The sample is taken beneath the installation. Splashing is mini­mised by the form of the outlet pipe.

The stainless steel outlet tube can be swung out of the operating
area to either side.

Installation Guidelines

• Positioning of the sampling location must be determined by
the person carrying out sampling. The defined positions must
be identified in the plan for sampling locations in drinking
water systems.

• The sampling valve can be installed horizontally or vertically
to any valve with testing lobes.

• Insure the piping system is pressure-free before installing the
sampling valve

• The valve housing is only tightened at closed position due to
possibility to align valve to right position during installation.

• Please check for closed condition after installing.
