Material selection is one of the most critical decisions in industrial valve engineering. The right choice affects not only how well a valve performs, but also how long it lasts and how safely it operates. Stanvalves & Control Systems helps clients across sectors select materials suited to their pressure, temperature and chemical exposure requirements — ensuring that valves function reliably over time.
Industrial environments vary significantly. From marine conditions and corrosive chemical processes to high-temperature steam systems, no single valve material is suitable for every situation. Understanding the properties of commonly used metals and alloys helps match valve construction to real-world demands.
Stainless steel is widely used in valve manufacturing due to its strong corrosion resistance and mechanical strength. Grades such as SS304 and SS316 are common choices across chemical, water treatment and food-grade applications.
Key advantages include:
Stanvalves & Control Systems uses stainless steel in valves designed for pharmaceutical processing, water systems, and offshore operations, where durability and cleanliness are critical.
Brass is often chosen for its ease of machining and affordability. It offers moderate corrosion resistance and is well-suited to low- to medium-pressure applications.
Typical benefits:
Stanvalves & Control Systems recommends brass for applications with minimal chemical exposure, such as building services, HVAC systems or light industrial use.
In highly corrosive or high-temperature environments, exotic alloys such as Hastelloy, Monel or Inconel are often required. These materials are engineered for resilience in extreme conditions, especially in marine, oil & gas and chemical production sectors.
Characteristics include:
Stanvalves & Control Systems supplies custom-fabricated valves using exotic alloys for critical infrastructure projects and aggressive fluid handling systems. Though these materials increase upfront cost, they often provide long-term value through reduced maintenance and replacement needs.
Corrosion is one of the leading causes of valve failure. In chemical plants, exposure to strong acids or solvents can degrade valve bodies and seals over time. In marine environments, salt and humidity accelerate material decay, particularly at interfaces and flanges.
The right material — or combination of materials — ensures that valves:
Stanvalves & Control Systems works with clients to analyse their fluid properties, operating temperatures and environmental conditions, ensuring corrosion resistance is engineered from the outset.
In addition to base materials, many valves benefit from protective coatings or internal linings. These add another layer of defence against corrosion, abrasion, and chemical degradation.
Common options include:
Stanvalves & Control Systems offers these solutions across its valve product lines, tailoring surface protection to each application’s specific needs.
The wrong material can lead to accelerated wear, safety risks or process contamination. Stanvalves & Control Systems helps customers make informed choices based on:
Each project is reviewed on a case-by-case basis. Where necessary, Stanvalves & Control Systems provides documentation, certificates and traceability to meet international quality and material assurance standards.
Material selection is more than a technical detail it's a strategic decision that affects performance, compliance and cost. Contact the team at Stanvalves & Control Systems to discuss the ideal valve material for your specific application and operating environment.
