Metallic and non-metallic Valve

Non-metallic materials are commonly used for valve components. The selection of non-metallic materials for valve design and for application-specific conditions is critical to ensuring product reliability. Like metallic materials used in valve designs, to meet reliability target selection of non-metallic materials is important to fulfill the design function of the component in the intended applications. In this article, we address some key areas to aid in the design and selection of non-metallic materials.

NON-METALLIC MATERIALS USED IN VALVES

Understanding material properties is essential for selecting the appropriate material for the valve design function and ensuring compatibility with the application requirements. It is crucial to have a thorough understanding of both the chemical and physical properties of the materials used in construction to effectively utilize a specific material for the intended purpose. By examining these properties carefully, one can make informed decisions to ensure the optimal performance and longevity of the valve system.

Application

• Chemical composition of the flow medium (critically important)
• Elastomer liners must withstand chemical attack and swelling
• Temperature limits of the material
• Solids content of the flow, if any (is there risk of abrasion?)
• Flow rates or velocity

The chemical properties of a material determine whether it can be used within a particular application includes:

• Chemical compatibility/corrosion resistance/chemical resistance
• Crystallinity
• Permeation
• Electrical conductivity
• Food safety

The physical properties of the material need to be taken into account to ensure functional performance, including under a full range of operating conditions:

• Strength: tensile, yield, compressive
• Elongation
• Flexural modulus
• Compression set
• Deformation under load
• Hardness (Shore durometer)
• Volume change: swelling, especially due to the flow medium
• Abrasion resistance
• Extrusion resistance
• Temperature rating: performance within given temperature range (Figure 1 shows examples)
