TS ISO 14617-4

TS ISO 14617-4 defines the part of the graphical-symbol system used in diagrams for actuators and related devices. Its focus is on giving a consistent way to represent elements that produce motion, force, or position change in a system so they can be identified clearly in technical drawings.

What actuator symbols represent

In general technical usage, an actuator is the element that converts a control signal or an input energy source into physical movement. That can occur in pneumatic, hydraulic, electrical, or mechanical drive arrangements. The symbols used in diagrams help distinguish basic actuator elements, complete actuator assemblies, and the associated actuating devices that drive them. This makes the same function easier to read across design, maintenance, and system documentation.

Position within the ISO 14617 family

This part belongs to the ISO 14617 series and refers users to ISO 81714-1 for the fundamental rules for creating and applying graphical symbols in diagrams. ISO 14617-1 provides the broader framework for symbol identification, registration numbers, presentation, and application. In that sense, TS ISO 14617-4 is not a general drawing guide; it concentrates on standardizing graphical representation for the actuator domain.

• Supports consistent visual representation of actuators in diagrams.
• Covers basic elements in actuators, complete actuators, and related actuating devices.
• General symbol-creation rules are found in ISO 81714-1 and the overview in ISO 14617-1.
• Useful for machine, process, and automation schematics.
