DYNATORQUE 360
Multiturn worm-gear operator
DYNATORQUE 360 multiturn worm-gear operator is commercial grade, worm-geared, and made for applications that require multiple output turns but not withstanding thrust loading.
These worm-gear operators lack positive output stops but have bores, keyways, and mounting dimensions as listed on the individual operator envelope drawings. Operators are assembled in position II (clockwise input results in clockwise output), and have one shop coat of black oxide primer. Handwheels are sold separately.
These 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 meet your application requirements.
