Parameters / Specifications Model: Fisher 1052 Size 60 Actuation type: Spring‑return, rotary (diaphragm) Service: On/off or throttling for quarter‑turn valves Power source: Pneumatic Mounting adaptations: H and J styles available (for different shaft/coupling configurations) Output shaft diameters (H mounting) for size 60: 28.6 mm (1‑1/8 in) or 38.1 mm (1‑1/2 in) Torque limits (H mounting) for size 60: up to 10,680 in‑lb (~1,206 N·m) Mounting adaptation J coupling torque limits for size 60 vary by shaft diameter (up to ~12,000 in‑lb for certain keyed shafts) Actuator sizes: 60 is one of the larger sizes in the 1052 line (other sizes include 40, 70) Operating temperature: Standard temperature service (depending on elastomer/diaphragm materials) Features: Splined output shaft/lever linkage to minimize lost motion, adjustment via turnbuckle, optional travel stops, manual hand wheel option, mounting pad for positioner Control type: Compatible with on/off or throttling control, when used with a positioner or direct pneumatic signal Valve type compatibility: Ball valve, butterfly valve, eccentric plug valve, triple‑offset valve pproximate weight: Varies significantly depending on size and options; for size 60 actuation portion alone the weight is substantial (tens of pounds) Certifications/standards: Available with CE/PED, ATEX, CUTR options depending on variant Travel: Nominal 90° rotation for standard quarter-turn, with adjustable stops for less or more rotation depending on valve design Pressure/Diaphragm information: The factory‑set spring and diaphragm pressure determine closing/opening signal pressure; typical diaphragm casing pressures for size 60 are around 0 to ~3.8 bar (~0‑55 psig) depending on configuration
