Overview
ISO 22153:2020 - Electric actuators for industrial valves: General requirements defines basic requirements and guidance for electric actuators used on on‑off and control valves. The standard covers classification, design principles, enclosure and corrosion protection, performance and conformity assessment methods. Combinations of electric actuators and gearboxes supplied by the actuator manufacturer are included. The standard explicitly excludes solenoid actuators, electro‑hydraulic actuators and electric actuators that are integral to valves.
Key topics and technical requirements
ISO 22153:2020 organizes technical requirements and guidance across the following areas:
- Classification and designation
- Actuator types, duty classes and actions on loss of power (stay‑put vs fail‑safe).
- Design and performance
- Endurance requirements for part‑turn, multi‑turn and linear actuators.
- Environmental design: ambient temperature, humidity, altitude, vibration, seismic loading.
- Enclosure protection (IP ratings) and external corrosion protection.
- Attachment interfaces to valves (references to ISO 5210 / ISO 5211).
- Self‑locking/braking, manual operation, travel and torque/thrust limitation.
- Motors, gearing lubrication, structural integrity and noise considerations.
- Electrical and control
- Cable entries, electrical connections, power‑supply tolerances and actuator duty performance.
- Optional controls: positioners, controllers, speed control, field‑bus interfaces, torque/position transmitters and data logging.
- Verification and lifecycle
- Type and production testing, endurance test procedures (Annex A), production process control.
- Marking, mandatory and optional documentation, packaging and conformity assessment.
- Supplementary guidance
- Informative annexes for actuator selection (Annex B) and load profiles (Annex C).
Practical applications and users
ISO 22153 is applicable wherever electric valve actuators are specified, procured, manufactured, installed or maintained, including:
- Valve and actuator manufacturers
- Process, petrochemical, water, power, HVAC and manufacturing engineers
- Specifiers, procurement teams and asset owners
- Testing and certification laboratories
Use cases include selecting actuators for safety or control applications, specifying environmental protection and corrosion resistance, defining fail‑safe behavior, and ensuring conformity through type and production tests.
