About this app

Comprehensive reference guide for automation engineers, technicians, maintenance teams, students, and fluid power professionals.

Key Features:
- ISO 1219 Pneumatic Symbols: Directional control valves, cylinders, logic elements, air service units (FRL), regulators, sensors, and actuators.
- Working Circuit Schematics: Direct speed control, cylinder reversal, cascade sequencing, two-hand safety logic, and air-saving circuits.
- Interactive Airflow Simulation: Visualize supply lines, pilot paths, exhaust routing, and cylinder motion directly on schematic diagrams.
- Standard Port Numbering: Full ISO 5599 numeric port designations (1, 2, 3, 4, 5, 12, 14) and legacy letter designations (P, A, B, R, S, Z, Y).
- Detailed Component Specs: Working principles, port layouts, operational sequences, and typical industrial automation applications.
- Quick Search & Filters: Instant lookup by symbol name, DIN/ISO code, valve type, or circuit complexity (beginner to advanced).
- Bookmarks: Save essential schematics and valve references for quick access during workshop design and on-site troubleshooting.

Whether designing automation systems, interpreting machine drawings, or studying industrial pneumatics, this reference provides clear schematics and accurate engineering data.
Explore ISO 1219 pneumatic symbols, circuits, and interactive schematics.
