Butterfly valves give you quarter-turn isolation and throttling in a compact, lightweight body — the practical choice where a gate valve would be too heavy, too tall or too slow to operate. A single disc rotates 90° within the pipe bore, so face-to-face length stays short and actuation is fast.
The Niagara butterfly valve range
Our range covers the FFB20 / FFB21, FFSD25 / FFSD30 / FFSD80 / FFSD81 / FFSD150, FSD30 / FSDG50 and FFS40 / FFS41 / FFS80 series, in wafer, lug and flanged configurations, with gear-operated and lever-operated options.
Where they are used
Water treatment and distribution, HVAC chilled and condenser water, fire protection loops, irrigation headers, and general industrial process lines — anywhere frequent isolation or flow regulation is required.
Selecting a butterfly valve
Specify by nominal size (DN), body style, pressure rating, seat and disc material for your medium, and whether you need manual, gear or actuated operation. Our engineering team can confirm the right configuration for your duty.
