Frequently Asked Questions
Common questions about ANYI gas cylinder valves and industrial gas valves.
Selection
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.
Each model page shows the connection designations recorded for that model. Tell us the connection your cylinder uses and the one your equipment or filling line uses, and send photos of both ends of the valve you use today, including any markings on it.
A connection is never assumed from a family name: the fit is confirmed for the exact model before quotation.
Documents & certificates
The certificates ANYI holds are published on the Certifications page, each shown as it was issued: an ISO 9001:2015 quality management system certificate, a TUV Rheinland type approval for transportable pressure equipment, a Bureau Veritas manufacturer proficiency test certificate, and a Korean KGS manufacture registration.
What a certificate covers is what the certificate itself states, and the page links to the original document so you can read it. Whether a certificate applies to the exact model you need is confirmed with our team before quotation.
Tell us the exact model and which document you need — a drawing, a datasheet, a manual or a certificate — and our team will tell you what can be provided for that model and send it to you.
A document is never implied for a model that does not have one. If something cannot be provided, we say so rather than sending you the document of a similar model.
Every value on a model page belongs to that exact model, not to its family. Where a value has not been confirmed for that model yet, the page says so instead of showing a figure that might not hold.
Nothing on a model page is estimated or carried over from a similar model. If you need a value the page marks as still to be confirmed, tell us the model and which value you need, and our team will confirm it before quotation.
Enquiries & contact
The exact model if you know it, the gas, the working pressure, the connections your cylinder and equipment use, the quantity and the delivery country. Photos of the valve you use today, including the markings on its body, help us match it.
By email, WhatsApp or phone — the details are on the contact page and at the foot of every page. On a product page the email and WhatsApp links already name the model you are looking at.
