Handwheels
Suited for Cameron products
6- to 48-in sizes, many in recessed or flat versions.
Memory-Stop Device
DYNATORQUE accessory
Cameron gear operators are modified with an infinitely adjustable memory-stop device suitable for valves and dampers, as well as most other quarter-turn applications requiring a self-locking mechanism. This configuration is ideal when a valve or damper ust always be opened or closed to the same exact position. The addition of a traveling nut module allows repeatable valve travel to the predesignated set point.
Our flexible manufacturing process allows us to offer both standard construction and custom configurations for customer-specific applications. Standard operators are available with various mounting interface dimensions. Custom-machined gears come with bores and bolt holes for direct mounting to the valve. Standard materials are cast gray or ductile iron, but we also offer a varied selection of alternate materials to your application requirements.
