Description

Wafer type centerline butterfly valve for installation between flanges. Available in NPS 2 to NPS 8 at 150LB pressure class, with cast iron or ductile iron body options. Seat materials include EPDM, NBR, FKM, and PTFE, suitable for a range of media including air, sewage, steam, gas, and oil.

Selection notes

This butterfly valve is a wafer type and centerline pattern, supplied for wafer installation.

Sizes run NPS 2" to NPS 8", in Class 125.

The body is offered in WCB and QT450 (EN-GJS-450-10), so the grade can be matched to the service rather than the other way round.

Seat and trim options are EPDM, NBR, FKM and PTFE. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.

Stated service media include air, sewage, steam, gas and oil.

It is catalogued for Water & Wastewater, HVAC and Industrial Process.

Built to API 609, MSS SP-67, DIN3202, BS EN558-1 and API 598.
