BF – DIN
The BF Series is a ball valve that matches a large range of applications. It features a split body construction and uses C-RPTFE seats for maximum chemical compatibility combined with minimum coefficient of friction. It is a bi-directional, zero leakage valve and has an ISO 5211 top works, which simplifies the actuator and gear operator mounting. It has a self-relieving seat design for cavity relief and is available in PN40 and PN16, short pattern F4/F5 and PN100, PN40 and PN16, long pattern F1.
