DATA SHEET

The BFS series of butterfly valve has a 316 Stainless Steel body, PTFE coated 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 a high quality anodised aluminium spring return pneumatic actuator (rack and pinion design). The spring return design of the actuator allows it to have a fail safe position should air be lost. The unique bonded catridge design of the valve 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. If sizes above 300mm are required please contact us.
