Key Information:

1. Core Functionality and Classification

Drive Principle: Compressed air propels the piston, driving the rack-and-pinion mechanism to achieve either a 0-90° angular stroke or a linear stroke for the damper.

Types:

Single-Acting: Relies on spring return; the air source provides power in only one direction.

Double-Acting: Air source provides bidirectional drive, eliminating spring return and enabling faster response.

2. Pricing and Brands

Price Range: From budget options (e.g., AT52 square shaft actuator at ￥73.50) to premium models (e.g., Honeywell CN7220A2007 priced at ￥1266.00).

?Major Brands: BELIMO, Honeywell, Siemens, etc. The BELIMO SM230ASR model costs approximately ￥483.85.
