Description
The Fisher 2052 spring-and-diaphragm rotary actuator is used on rotary-shaft valve bodies for throttling or on-off applications. The compact design reduces valve/actuator envelope dimensions for greater mounting versatility. Features include linkage-less feedback via contactless magnetic array, single pivot linkage reducing lost motion, nested spring design requiring no bench set, ISO 5211 mounting interface, NAMUR VDE/VDI 3845 bolt pattern for accessory mounting, and field-reversible right- or left-hand mounting. All parts in the fail-safe mechanism (steel, cast iron, ductile iron) ensure safety integrity in fire events. Available in three sizes accommodating shaft sizes 12.7 to 38.1 mm.
