Description:
The BFD (supersedes the BFK) series has a ductile iron body, 316 stainless steel disc, 
EPDM seat (as standard but also available in FKM) and a spring return pneumatic actuator making it suited to a wide range of industrial applications. 
These are Watermark, Standards Mark and WSAA (Water Service Association of Australia) certified (with and EPDM seat). 
These wafer butterfly valves will fit all standard flanges (DIN PN6/PN10/PN16/PN25, ANSI 150, JIS 5k/10k, AS2129 Table D/E) 
and are operated by a high quality spring return (rack and pinion design) anodised aluminium pneumatic actuator. 
This enables a fail safe position if air should be lost. 
The unique bonded cartridge design of the butterfly valve gives it a longer life span, 
allows vacuum to be run through it and enables the seat to be replaceable if ever the need should arise. 
Common applications include water trucks, irrigation, water treatment and other industrial applications. 
If using on a cement hopper please contact us. We recommend going up a size in actuator to compensate for the weight on the disc. 
If sizes above 600 mm are required please contact us. Please note that different sizes have different numbers of guide holes on the outside of the valve.
