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.
