Description

Wafer-type butterfly valve with a cast iron body designed for installation between flanges. Available in multiple body, disc, seat, and stem material combinations to suit a range of media. Suitable for water supply, HVAC, industrial circulation, and wastewater treatment applications.

Selection notes

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

Sizes run DN50 to DN1000, in PN10, PN16, Class 150, Class 300.

The body is offered in CI, DI, CS and SS, so the grade can be matched to the service rather than the other way round.

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

Stated service media include chemicals, air, water, steam, oil and salts.

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

Working temperature is -30°C to 135°C.

Built to API609, ANSI16.34, JISB2064, GB T12238 and DIN3202.
