DATA SHEET

The BFS series of butterfly valve has a 316 Stainless Steel body, 316 S.S disc and a PTFE coated NBR seat making them suited to a wide range of high end applications. These wafer butterfly valves will fit all standard flanges and are operated by either a lever (304 Stainless Steel) or gear box (FBE coated Ductile Iron however full stainless steel gear box is available upon request). The unique bonded catridge design gives them a longer life span, allow vacuum to be run through them and makes them replaceable if ever the need should arise. Common applications include food industry, chemicals, pharmaceuticals and other industrial applications.
