ISO 5211 is an international standard that defines the mounting interface between pneumatic actuators and industrial valves or other rotary equipment. Pneumatic actuators compliant with this standard ensure interchangeability and simplify integration across different manufacturers.
Key Features of ISO 5211 Pneumatic Actuators:
- Standardized Mounting – The flange dimensions, bolt patterns, and drive shaft specifications are uniform, enabling easy replacement or upgrades.
- Compatibility – Works with quarter-turn valves (e.g., ball, butterfly, plug valves) from various brands.
- Robust Design – Typically made from aluminum, stainless steel, or engineered plastics for durability in harsh environments.
- Efficient Operation – Converts compressed air into mechanical motion (double-acting or spring-return models available).
Applications
Widely used in oil & gas, water treatment, chemical processing, and automation systems where reliable valve actuation is critical.
By adhering to ISO 5211, manufacturers and end-users benefit from reduced downtime, simplified maintenance, and global supply chain flexibility.
For detailed specifications, refer to the official ISO 5211:2017 standard documentation.
