Start from the gas. ANYI valves are grouped by the medium they are built for, then by product family, and each family lists its exact factory models with the working pressure, bore and connection designations recorded for them.

If you are unsure, send us your details through Technical Matching and our team will suggest the models to look at.

The catalogue is organised by medium: oxygen and multi-gas, CO2, nitrogen / argon / helium, hydrogen, acetylene, fuel gas and CNG, N2O, chlorine, and specialty gas. Each medium lists the valve families built for it, and each family lists its exact factory models.

Whether a particular model suits your gas, your working pressure and your cylinder is an exact-model question. Open the model page for the recorded values and confirm them with our team before ordering.

Send clear photos of the valve from several sides, of the markings stamped on it and of both connections. Our team compares them with ANYI factory records and tells you whether an ANYI model corresponds, or what still needs to be confirmed.

Not automatically. Models in one family can differ in working pressure, bore and connections. Each product page lists the models of its family side by side; confirm the choice with our team before ordering.
