Nickel Alloy Valves

We supply nickel alloy valves – including forged and cast gate, globe, and check valves – available for both project installations and emergency/maintenance requirements. These valves are engineered to connect with industrial equipment and provide precise control over liquids, gases, and pressure processes.

Materials

Our valves are manufactured from high-performance nickel alloys, most commonly:

Copper-Nickel

Monel® (copper–nickel alloy with enhanced strength and corrosion resistance)

Inconel® (nickel–chromium alloy designed for high-temperature, high-stress environments)

Key Properties of Nickel and Its Alloys

Nickel itself is known for its high strength, ductility, malleability, and corrosion resistance. When alloyed with copper, chromium, or other metals, these properties are further enhanced to meet demanding industrial requirements.

Performance Characteristics

Hard metal with excellent wear resistance

High mechanical strength and creep strength at elevated temperatures

Good electrical conductivity (especially with copper-nickel alloys)

Heat resistance for high-temperature applications

Corrosion resistance in aggressive environments including seawater, chemical, and petrochemical media

Excellent durability with long service life

High-pressure tightness, ensuring safety and reliability under demanding conditions

Specification

Features

It is used extensively because of their corrosion resistance, high-temperature strength, and special magnetic and thermal expansion properties.

The major alloy types that are used are:

· Copper-Nickel alloys and Nickel-Copper alloy valves

· Nickel-Chromium and Nickel-Chromium-Iron alloy valves

A typical nickel-copper alloy valve is the 400 grade (UNS N04400). This contains 63% nickel minimum, 28-34% copper, and a maximum of 2% manganese and 2.5% iron. These nickel alloy valves are used where higher strength is required compared to pure nickel. They have a wider range of environments where they resist corrosion but in some specialized applications, such as strong alkali contaminants, nickel would be superior. They find wide applications in oil refining and marine applications where long corrosion-free life is required. Because of their good thermal conductivity, they frequently are used for heat exchangers where seawater is one of the fluids concerned.

These nickel-chromium base alloy valves are used extensively in applications where heat resistance and/or corrosion resistance are required. Where corrosion resistance is significant, molybdenum is used as an alloying addition. Common trade names are HASTELLOY, INCOLOY, INCONEL, NICROFER, and NIMONIC.
