Special Alloy Valves for Corrosive Petrochemical Applications

The Alloy Valve Stockist stocks a broad range of alloy valves, in ball, globe, check, butterfly and knife configurations. As a valve stockist, we hold valves in titanium, hastelloy, duplex, super duplex, monel, incoloy, inconel, alloy 20, both in stock and can also deliver against tight lead times.

Alloys are made in many qualitied and forms: forged, cast, bar stock and other standards that are suitable for valve manufacturing. In order to unify the description of the material, you will often see the use of the Unified Numbering System denoted by the three-letter "UNS" tag prior to a single-letter plus five-digit code, such as UNS N04400 for monel, or UNS S32750 for Super Duplex.

A prefix of S indicates stainless steel alloys, C for copper, brass, or bronze alloys, T for tool steels, etc. The first three digits often match older three-digit numbering systems, while the last two digits indicate more modern variations. For example, Copper Alloy No. 377 (forging brass) in the original three-digit system became C37700 in the UNS System. The UNS is managed jointly by the ASTM International and SAE International . A UNS number alone does not constitute a full material specification because it establishes no requirements for material properties, heat treatment, form, or quality.

Customers are welcome to identify their material requirements by using the UNS when enquiring for our exotic alloy valves:
