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.

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 acopording to EN 1717 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 http://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 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 to entry 2: 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 i.e. frost

taps)

Note 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.
