1 Scope
This document specifies:
a) the field of application;
b) the requirements of hose union anti vacuum valves;
c) dimensional and physio-chemical properties, and properties of general hydraulic, mechanical and
acoustic design of hose union anti-vacuum valves of nominal sizes DN 15 up to and including DN 25;
d) marking and technical product information.
This document specifies the characteristics of hose union anti-vacuum valves of nominal size DN 15 up
to and including DN 25 that are suitable for use in drinking water systems at pressures up to and
including 1 MPa (10 bar) and temperatures up to and including 65 °C and for 1 h at 90 °C.
HB protects against back siphonage only and is installed in vertical downward flow position.
HD protects against back flow and is installed in vertical downward flow position.
HB and HD anti-vacuum valves are for installation exclusively at the connecting point between stop valve
and hose in vertical downward flow position.

3 Terms and definitions
For the purposes of this document, the terms and definitions in EN 1717:2000 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at https://www.iso.org/obp
3.1
hose union anti-vacuum valve HB
valve equipped with air inlet ports, which are closed at zero flow and when water flows in the intended
direction above atmospheric pressure
Note 1 to entry: The air inlets are opened if there is subatmospheric pressure at the water inlet and closed to be
watertight again when the supply lines are back to at least atmospheric pressure
Note 2 to entry: For the purpose of this standard, “hose union anti-vacuum valve(s)” are hereafter referred to as
“device(s)”
3.2
hose union anti-vacuum valve HD
valve HB with integrated check valve EB located upstream (monoblock/combined products e.g. frost
taps)
Note 1 to entry: For the purpose of this standard, “hose union anti-vacuum valve(s)” are hereafter referred to as
“device(s)”
4 Nominal size
The nominal size of the devices (DN designated) shall correspond to the nominal size of the threaded
inlet connection according to Table 1.
