This chain wheel is made from ductile iron, sized for a 6 to 7.5 in diameter range. Chain wheels of this type fit onto the handwheel or gearbox shaft of a manually or chain-operated valve, allowing the valve to be opened and closed from floor level via a hanging chain where the valve itself is mounted out of reach.

Exact bore size, keyway, and hub configuration for this wheel are not recorded against this catalog entry, and this item is marked as discontinued, so fitment should be confirmed against your specific valve/gearbox shaft before ordering. Supplied by Z&F Corporation — our technical sales team can help confirm fitment or source a current equivalent when requesting a quote.
