Description
Covering 50 mm to 80 mm at PN 16, this is Honeywell’s manual Butterfly Valve, Gearbox Operated (DI Disc). The disc stays in the flow path when open, which costs a little pressure drop but keeps the valve short, light and cheap to support. Gear operation keeps the effort manageable at the larger bores, where a lever would need more force than one person can apply. Grey cast iron to IS 210 keeps the cost sensible in the larger sizes, provided the duty is steady rather than shock-loaded. The wafer body clamps between two pipe flanges, keeping face-to-face length and weight to a minimum. Every size in the range is listed above with its catalogue number and price.
