Description
A triple eccentric butterfly valve with metal-to-metal seating, designed for high-temperature, abrasive, and high-pressure applications. Features an offset disc geometry that minimises wear during operation. Available in multiple body materials including carbon steel, stainless steel, and various alloys.
Selection notes
This butterfly valve is a triple eccentric, metal seated and eccentric pattern, supplied for flanged installation.
Sizes run DN50 to DN600, in Class 150.
The body is offered in A216 Gr. WCB, A216 Gr. WCC, A216 Gr. WCA and A352 Gr. LCB, so the grade can be matched to the service rather than the other way round.
Stated service media include crude oil, natural gas, steam, gas and slurry.
It is catalogued for Oil & Gas and Industrial Process.
Working temperature is -29°C to 200°C.
Built to API 609, ASME B16.10, API 6D, API 598 and ASME B16.34.
