Add symbols, arrange them in order (air preparation → valve → cylinder), and send them with your request — it helps us understand faster exactly what you need. The symbols follow the DIN ISO 1219-1 standard, not invented — simplified only for size, not for construction. This is not a precise CAD tool.
Drag symbols to arrange them. Double-click a symbol to delete it. The blue tools (Relay/PLC/Flow meter) are control/measuring elements, not pneumatic — for sketching the signal/control part.
Builds automatically from the symbols you place. Copy it into your request — we'll match it to specific product codes and quote from our Riga stock.
This tool only places symbols — it does NOT draw the tubing automatically. The exact model is chosen by pressure, size and application — send us the list and we'll match it to specific products from stock.
The generic ISO 1219 energy-source symbol (circle + open triangle) — the compressor is the energy source, not a pneumatic component downstream.
Filter (diamond + dotted line + drain funnel) – Regulator (square + two-way arrow + adjustability arrow + relief path) – Lubricator (empty diamond), enclosed by a dashed line = an "Air combination" unit.
5 ports: 4/2 on top (to the cylinder), 1 bottom-centre (supply), 5/3 exhausts with "T" closed ends.
Body + piston (filled bar) + a rod running from the piston through the chamber and out (not a detached stub). Two ports at the bottom on both ends.
A contact-switch symbol — a SIGNAL, not an air line.
The simplest valve — either passes or blocks (T-shaped closure). Good for shutting off the main air supply.
3 ports, 2 positions — the standard choice for controlling a single-acting cylinder.
An internal spring returns the rod — needs only ONE air port. Cheaper, but a weaker return stroke than a double-acting one.
Rotates (rather than slides) — for gates/dampers/turn assemblies, typically 90°-180°.
Passes air in only ONE direction — a ball/seat symbol. Good for preventing backflow / holding pressure.
An adjustable restrictor (top) + a free-flow check valve (bottom) — throttles in ONE direction, passes freely in the OTHER. The standard cylinder speed controller.
Lets the cylinder’s exhaust air escape LOCALLY, not back through the long tube and valve — speeds up the motion.
Fitted on the valve exhaust port — reduces the noise of escaping compressed air. Cheap, often forgotten, but essential for workplace safety/noise.
A Venturi constriction turns compressed air into vacuum — no moving parts.
Circle + needle = a pressure indicator. Handy on the FRL outlet to see the working pressure.
Switches an ELECTRICAL contact when pressure crosses the set threshold — a signal to the PLC/relay, not an air line.
Two inlet ports, one outlet — whichever signal is first/stronger passes through. Good for two-hand safety / OR-logic circuits.
An electrical-schematic coil, not a pneumatic symbol — simplified (2 terminals, rectangle). (an electrical part, not a pneumatic component).
Has no unique ISO symbol of its own — always a labelled rectangle with I/O lines. (not a pneumatic product).
Not in the ISO1219 4-page symbol table itself — the widely-accepted instrument-"bubble" convention (circle + letters), like the pressure gauge.
