ISA 96-03 Test for Pneumatic Actuators

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISA 96-03 testing. This standard provides the basic requirements for double-acting and single-acting types of pneumatic valve actuators used for on-off and modulating valve duties. It contains guidelines, recommendations and methods for manufacturing, process control, device protection and testing. It does not apply to pneumatic actuators that are integral parts of control valves.

Other requirements or conditions of use that differ from those specified in this standard should be notified to the manufacturer by the purchaser prior to ordering.

• Pneumatic actuator: A device that converts compressed air into mechanical motion to operate a valve.
• Piston: The component that converts pneumatic energy into linear motion.
• Spring: A component used to return the actuator to its normal position in the absence of pneumatic pressure.
• Diaphragm: A flexible membrane used to transmit pneumatic force from the actuator to the valve stem or stem.
• Actuator size: The size of the actuator, typically expressed in terms of the diameter of the piston or diaphragm.
• Actuator stroke: The maximum linear distance the actuator can travel.
• Air pressure rating: The maximum pneumatic pressure the actuator can withstand.
• Flow capacity: The amount of air flow required to operate the actuator.
• Positioner: A device that receives a control signal and adjusts the position of the actuator to achieve the desired valve position.
• Pilot valve: A valve that controls the flow of compressed air to the actuator.
• Solenoid valve: An electrically operated valve to control the flow of compressed air to the actuator.

By following these standard definitions and terminology, designers, manufacturers and end users of pneumatic valve actuators can more effectively communicate about actuator requirements, capabilities and performance. This ultimately helps ensure that pneumatic actuators are designed and operated safely and efficiently.
