This document specifies:
a) field of application;
b) requirements for pressurised air inlet valves;
c) dimensional and the physico-chemical properties and the properties of general hydraulic, mechanical and
acoustic design of pressurised air inlet valves DN 15 to DN 50;
d) test procedure and requirements for verifying these properties;
e) marking and presentation;
f) acoustics.
This document specifies the characteristics of pressurised air inlet valves DN 15 to DN 50 that are suitable for
use in drinking water systems at pressures up to 1 MPa (10 bar) and temperatures up to 65 °C and for 1 h at
90 °C.
