Status: active
Page Count: 26
ICS Code (Drinking water): 13.060.20
ICS Code (Check valves): 23.060.50
scope:

This document specifies the field of application, the dimensional, the physico-chemical, the design, the hydraulic, the mechanical, and the acoustic characteristics of in-line anti vacuum valve family D Type A.

This document covers in-line anti vacuum valve family D Type A, intended to prevent pollution of potable water by backflow, caused by backsiphoning only.

It is applicable to in-line anti vacuum valve in denominations DN 10 up to DN 50.

It covers in-line anti vacuum valve of PN 10 that are capable of working without modification or adjustment:

- at any pressure, up to 1 MPa (10 bar);

- with any pressure variation, up to 1 MPa (10 bar);

- in permanent duty at a limited temperature of 65 °C and for maximum 1 h at 90 °C.

It specifies also the test methods and requirements for verifying their characteristics, the marking and the presentation at delivery.
