Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Enclosure rating — Series 92 | NEMA 4X + NEMA 7 (hazardous locations) + ATEX Exd IIB T4 | Asahi/America — Actuation Basics (Electric & Pneumatic Actuator Engineering Reference) |
| Output torque range (electric line) | 150 in-lbs to 48,000 in-lbs | Asahi/America — Actuation Basics (Electric & Pneumatic Actuator Engineering Reference) |
| Max ambient temperature | 150°F (Series 92/94/10) | Asahi/America — Actuation Basics (Electric & Pneumatic Actuator Engineering Reference) |
| Sizing safety factor | Minimum actuator output torque = valve torque × 1.25 (Asahi's standard 25% safety factor) | Asahi/America — Actuation Basics (Electric & Pneumatic Actuator Engineering Reference) |
Asahi's design is declutching — manual override disengages the motor from the output gearing before hand-cycling. Non-declutching designs used by some other manufacturers instead wind the motor backwards during manual override, "often times damaging the windings and armature" — a real reliability failure mode worth checking before swapping actuator brands on an existing water-treatment valve.
Series 92 is the only Asahi electric actuator line with full hazardous-location certification (NEMA 7, UL1203 Class 1 Div 1&2, ATEX) — the right call isn't 'an actuator,' it's matching the enclosure rating to whatever classified area the valve sits in, something a generic torque-only spec sheet won't flag.
