Industrial valves - Check valves of thermoplastics materials (ISO 16137:2006)
EN ISO 16137:2006

This European Standard specifies requirements and tests for check valves of thermoplastics materials with the function to allow the flow of liquid fluids through the valve in one direction only and to prevent backflow.
This standard is applicable to check valves to be installed in industrial pipe systems, irrespective of the field of application and the liquid fluids to be conveyed. For other and/or special applications special requirements may apply.
The range of DN is:
DN 8, DN 10, DN 15, DN 20, DN 25, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300, DN 350, DN 400, DN 500 und DN 600.
The range of PN and Class is:
PN 4, PN 6, PN 10, PN 16, PN 25, Class 150 und Class 300.
The requirements specified by this standard concern the design, functional characteristics and manufacture of diaphragm valves, their connection to the pipe system, the body materials and their pressure/temperature rating between - 40 °C up to + 120 °C, for a lifetime of 25 years.

This document specifies, the dimensional, the physical-chemical, the design, the hydraulic, the mechanical and the acoustic characteristics of mechanical disconnectors flow actuated Family G, type B.
This document is applicable to mechanical disconnectors flow actuated in nominal sizes DN 8 up to DN 250, intended to prevent the return of water having lost its original sanitary and drinking qualities (called “polluted water” in this document), into the potable water distribution system whenever the pressure of the latter is temporarily lower than in the polluted circuit.
This document covers the mechanical disconnector of PN 10 that are capable of working without modification or adjustment:
- at any pressure up to 1,0 MPa (10 bar);
- in permanent duty at a limit temperature of 65 °C and 90 °C for 1 h maximum.
It specifies also the test methods and requirements for verifying these characteristics, the marking and the presentation at delivery.
