Description
A wafer-type butterfly valve with a ductile iron disc and EPDM seat, fitted with a gear operator for controlled operation in medium to large diameters. The body is available in cast iron, ductile iron, carbon steel, or stainless steel. Designed for shut-off service in water supply, wastewater, cooling, and building services pipelines.
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, PTFE, FKM and NBR. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
Stated service media include water, chemicals, air, steam, oil and salts.
It is catalogued for Water & Wastewater, HVAC and Industrial Process.
Working temperature is -30°C to 135°C.
Built to API 609, ANSI 16.34, JIS B2064, GB/T 12238 and DIN 3202.
