NEN-EN-ISO 21787

Industrial valves - Globe valves of thermoplastics materials

active
Organization: NEN
Publication Date: 1 April 2006
Status: active
Page Count: 29
ICS Code (Globe valves): 23.060.10
scope:

This International Standard specifies requirements for the design, functional characteristics and manufacture of globe valves made of thermoplastics materials intended for isolating and control service, their connection to the pipe system, the body materials and their pressure/temperature rating between - 40 C and 120 C, for a lifetime of 25 years, and also specifies their tests. This International Standard is applicable to hand- or power-operated valves to be installed in industrial pipe systems, irrespective of the field of application and the fluids to be conveyed.
