The standards behind every Valvax valve
A quick reference to the design, testing and dimensional standards our range is built and certified to.
| Standard | What it governs |
|---|---|
| API 6D | Pipeline ball and check valves — design, testing and documentation for pipeline service. |
| API 600 | Bolted-bonnet steel gate valves for petroleum and natural gas industries. |
| API 602 | Compact forged gate, globe and check valves up to 4" NB. |
| API 598 | Valve inspection and testing — the shell and seat test every Valvax valve passes before dispatch. |
| API 607 / 6FA | Fire type-testing for quarter-turn and other valves with soft seats. |
| API 609 | Butterfly valves — double-flanged, lug and wafer styles. |
| ASME B16.34 | Pressure–temperature ratings for flanged, threaded and welding-end valves. |
| ASME B16.5 | Pipe flanges and flanged fittings — governs our flanged end connections. |
| ASME B16.10 | Face-to-face and end-to-end dimensions of valves. |
| ASME B16.25 | Butt-welding end preparation. |
| ISO 17292 | Metal ball valves for petroleum, petrochemical and allied industries. |
| BS 1873 | Steel globe and globe stop-and-check valves for the petroleum industry. |
| BS 5156 | Diaphragm valves — the standard behind our diaphragm range. |
Common Questions
Asked by specifiers, answered by engineers
How do I get a datasheet or dimensional drawing?
Request it through the contact form with the valve model or category — we issue documentation per enquiry so you always receive the current revision, usually within one working day.
What pressure classes do you manufacture?
ASME Class 150 through 2500 across the cast range, and Class 800–2500 in compact forged valves. Diaphragm valves are rated PN 10–16.
Which materials are available?
Standard bodies in ASTM A216 WCB carbon steel, A351 CF8/CF8M stainless and A995 5A duplex; forged valves in A105, F304/F316 and F11/F22. Exotic materials and NACE MR0175 sour-service options are quoted per enquiry.
How is every valve tested?
Each valve is hydro-tested to API 598 — shell, seat and backseat — in test bays rated to Class 2500. Fire-safe designs are type-tested to API 607 / 6FA. Third-party witness inspection is welcome.
What are typical lead times?
Standard catalogue valves typically ship in 6–10 weeks depending on size and class. Bespoke configurations are quoted with a firm delivery at the engineering-review stage.
Can you match a competitor valve or legacy installation?
Yes — send the nameplate details or the original datasheet and we will propose a dimensionally interchangeable equivalent from our range.
