BF Equalizers® utilize an elastomeric bladder which prevents contact between the process fluid and the compressed air or gas. When a pulse is created, fluid enters the wetted chamber of the BF Equalizers®, displaying the bladder, compressing the air/gas, and absorbing the shock. When the liquid pressure decreases, the gas expands, pushing the fluid back into the process line. Wilden offers the BF Equalizers® in sizes ranging from .953 cm (3/8") to 7.62 cm (3"), bolted, as well as flanged connections (ANSI and DIN). Wilden also offers high pressure dampeners, food grade with tri-clamp, sanitary with tri-clamp, as well as an extended Teflon® family.
