Description
A triple offset wafer-type butterfly valve featuring metal-to-metal sealing for and reduced seat wear. The wafer body is designed for installation between pipeline flanges in space-constrained applications. Suitable for high-temperature and high-pressure service in oil and gas, chemical processing, and energy industries.
Selection notes
This butterfly valve is a wafer type, triple eccentric and triple offset pattern, supplied for wafer installation.
Sizes run NPS 16, 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 and natural gas.
It is catalogued for Oil & Gas.
Working temperature is -29°C to 200°C.
Built to API 609, ASME B16.10, API 6D, API 598 and ASME B16.34.
