Description
A concentric butterfly valve in which the valve stem axis, butterfly plate centre, and body centre are coaxial. Designed for on-off and flow control duties in pipeline systems across a wide range of media. Material selection for disc, stem, and seat allows adaptation to demanding services such as desulphurisation, vacuum, and seawater desalination.
Selection notes
This butterfly valve is a concentric pattern, supplied for flanged installation.
Sizes run DN50 to DN1600, in PN2.5, PN6, PN10, PN16, PN25, Class 75, Class 150.
The body is offered in Cast Iron, Carbon Steel, Stainless Steel and Alloy Steel, so the grade can be matched to the service rather than the other way round.
Stated service media include water (supply and drainage), gas, petroleum products, chemical media, food-grade media and pharmaceutical media.
It is catalogued for Water & Wastewater.
Working temperature is -46°C to 120°C.
Built to API 609, GB/T 37621, GB/T 12238, GB/T 12224 and ASME B16.10.
