Description
Butterfly valve designed for industrial ventilation and gas transportation systems, featuring a high-strength carbon steel or stainless steel valve body with a low-torque sealing structure for regulating large gas flows. Available in centreline or eccentric configurations with a multi-level sealing system and wear-resistant sealing rings for dusty or high-temperature environments. The valve stem and butterfly plate are integrally forged, providing high strength and extended service life. Suitable for flow regulation and shut-off duty in ventilation and dust-removal ducting across power, metallurgical, chemical, building materials, and glass industries.
Selection notes
This butterfly valve is a ventilation, centreline and eccentric pattern, supplied for flanged and butt weld installation.
Sizes run DN100 to DN4000, in PN6.
The body is offered in 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 air, gas, dusty cold air and dusty hot air.
It is catalogued for HVAC.
Working temperature is 0°C to 600°C.
Built to API 609, ASME B16.34, JB/T8692, ASME B16.10 and GB/T12221.
