Description
A wafer-type butterfly valve manufactured to API standards in cast steel and stainless steel variants. Available in sizes NPS 2" to 48" with pressure ratings of Class 150LB and 300LB. Suitable for industrial applications requiring bidirectional sealing with worm gear actuation.
Selection notes
This butterfly valve is a wafer type pattern, supplied for wafer installation.
Sizes run NPS 2" to NPS 48", in Class 150, Class 300.
The body is offered in ASTM A216 WCB, ASTM A351 CF8 and ASTM A351 CF8M, so the grade can be matched to the service rather than the other way round.
It is catalogued for Oil & Gas.
Built to ASME B16.10, API 598, ASME B16.5 and ASME B16.47.
