Sɛ nsɛnkyerɛnne no nhyɛso no kɔ soro a, push poma no kɔ fam, a wɔfrɛ no actuator a ɛyɛ papa-actingator; Sɛ sɛnkyerɛnne no nhyɛso no kɔ soro a, wɔfrɛ vertebral rod no kɔ soro no, wɔfrɛ no reaction-acting actuator.
Nea ɛto so abien no, nkyerɛase a wɔde ma wɔ mframa a wɔde yɛ adwuma ho:
Ɛyɛ actuator a ɛde mframa nhyɛso di dwuma de ma valve a ɛbue, ɛto mu anaa nea ɛhyɛ so no kɔ. Wɔsan frɛ no mframa a ɛma mframa bɔ anaasɛ mframa a ɛma mframa bɔ kɛse, nanso mpɛn pii no wɔfrɛ no mframa a ɛma mframa bɔ kɛse.
Actuator ne adjustment mechanism a pneumatic actuator no yɛ nkabom mũ, na actuators no bi ne membrane type, piston type, fork type ne rack ne pinion type.
