3 factors to consider when choosing a material for fluid transfer systems.

When it comes to designing a valve, selecting the right material is crucial for ensuring efficiency, longevity, and safety. Here are three key factors to consider when choosing a valve material:

  1. Fluid Compatibility: Whether it is corrosive chemicals, hydraulic fluids, or delicate pharmaceutical compounds, the material chosen must exhibit compatibility with the intended medium to prevent degradation or contamination. Begin narrowing material possibilities by considering:
  • The nature of the medium that will flow through the valve.
  • Any chemical compatibility needs to prevent degradation or contamination.
  • Material recommendations: stainless steel for corrosive fluids, KYNAR for aggressive solvents, and medical-grade polymers for pharmaceutical compounds.
  1. Application Temperature and Pressure: By carefully assessing the anticipated operating conditions, engineers can select materials that ensure optimal performance and reliability. Further target possible material options by determining the following:
  • Evaluate the operating environment’s temperature to understand how the material will maintain functionality.
  • Determine the operating pressure parameters to verify material can handle the stress without failure.
  • Material recommendations: stainless steel for high temperatures, reinforced polymers for high-pressure conditions.
  1. Regulatory Compliance: Adhering to industry compliance regulations is a non-negotiable aspect of the material selection process. Familiarity with these regulations ensure that materials are not only safe but also legally approved for use in their respective applications. Some common regulations are:
  • National Sanitation Foundation (NSF): This organization sets the standard for food, water, and consumer goods products.
  • Food and Drug Administration (FDA): The FDA oversees the safety of drugs, medical devices, food, and other items affecting public health.

By carefully considering these three factors—fluid compatibility, application temperature and pressure, and regulatory compliance—engineers and designers can select materials that optimize the performance, durability, and safety of fluid transfer systems.
