Specifications:
The document provides detailed specifications for the JHA0255DA model, a rack and pinion pneumatic actuator. Key dimensions are provided in millimeters, including various component measurements such as A (68 mm), B (75 mm), and others up to φd (23 mm). The air connection is specified as M5*8 G1/4”.

Performance Data:
The actuator's performance is detailed in terms of air supply pressure, both in bar(g) and psi, with corresponding output torque values in N.m and lbf.in. The pressure range is from 2 to 8 bar(g), and the media used should be clean, dry, and non-corrosive compressed air.

Operating Conditions:
The actuator operates within a temperature range of -40 to 150°C, depending on the specific model variant (high, standard, or low temperature). The stroke is specified as 90±5°.

Standards and Compliance:
The actuator complies with EN 15714-3 and ISO 5211 standards. The flange and bi-square drive are also compliant with ISO 5211, and the solenoid valve mounting interface follows VDI/VDE 3845 (NAMUR) standards.
