Babbitt Chain Wheels & Pocket Wheels For Valves | Boiler Supplies Solid Hub Hammerblow Chainwheels
Solid hub hammerblow chainwheels with ductile iron rims and malleable iron guide arms. Use these chainwheels to operate high pressure valves or valves that are hard to open and close. These chainwheels mount directly to the valve shaft, eliminating the valve hand wheel. These chainwheels come complete with rim and chain guide. This style is also available in the safety wheel configuration. Babbitt solid hubs eliminate the need for handwheels by mounting directly to the valve or geared operator stem. Like all Babbitt chain wheels, the solid hub controls overhead valves economically and permits direct-to-shaft operation providing safety and versatility. Hubs can be bored to user specifications, or shopped solid for customer drilling. Consult PPI for custom boring charges. Custom bored chain wheels are non-returnable.
Chain Wheel uses Brass Chain.
