What is ISO 16139— Gate valves of thermoplastic materials about?
ISO 16139 specifies requirements for the design, functional characteristics and manufacturing of gate valves made of thermoplastics materials intended for isolating 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.
ISO 16139 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.
NOTE 1 Industrial pipe systems also include systems for water supply for general purposes, drainage and sewerage.
NOTE 2 Special requirements can apply to pipe systems for water for human consumption.
NOTE 3 Different DN and/or PN can be declared by the manufacturer.
