Codes indicated with numbers:

11xxx.1 supplied with G 3/8" coupling

11xxx.2 supplied with G 1/2" coupling

11xxx.3 supplied with G 3/4" coupling

1. To require chemical nickel plating add NK to the article's code
ex. 11001.1NK

2. To require ceramics water head valve (1/4 turn) add C to the article's code
ex. 11001.1C



Water taps can be supplied with oil bath head valve and sealing in EPDM or with ¼ turn ceramics head valve.

Nozzle with possibility of disassembly in compliance with DIN 12898 regulation.

Handles in compliance with EN13792:2000 norm, manufactured in ABS;
acid resistant material.

Threads in compliance with IS0228/1 regulation, B tolerance class.

Taps are built following the DIN12918 norm.


FAR can furthermore supply for demineralised water all the series with an internal chemical nickel-plating with a tickness of 17 microms, to have the desired article with this treatment the customer just needs to add to the article the NK abbreviation.

For ultra pure waters FAR manufactures PP and PVDF taps with recirculation.
Maximum working pressure 10 Bar.


Hereunder are shown the charts of water taps output; these results were acquired in the following conditions: operational pressure 10 Bar, temperature included between 10° and 25° and with a range of measurement uncertainty of +/- 2%.

The output curves "Qw" as a function of the supply pressure "P" hereunder indicated were interpolated previously, using the method of square minimums, in order to reach the equation of the characteristic curve Qw = f x (p) of the general kind Q = k x p raised to the nth power.
