VALVA provides a comprehensive range of stainless steel valves engineered for durability, corrosion resistance, and high-pressure integrity. From standard industrial processing to demanding chemical environments, our stainless steel solutions are manufactured to meet the highest API, ASME, and DIN standards.
Core Materials & Properties
We specialize in the two most critical grades of stainless steel used in modern industry:
- 304 / 304L Stainless Steel:The most versatile and widely used stainless steel. It offers excellent weldability and good resistance to atmospheric corrosion and many organic and inorganic chemicals.
- Best for: Food processing, water treatment, and mildly corrosive industrial environments.
- 316 / 316L Stainless Steel:Containing molybdenum for enhanced performance, 316L provides superior resistance to chlorides and pitting. The “L” (low carbon) version ensures better protection against intergranular corrosion after welding.
- Best for: Marine applications, chemical processing, and pharmaceutical industries.
Why VALVA Stainless Steel?
- Precision Casting: Our valves utilize high-quality investment casting (lost wax) and sand casting processes to ensure a smooth surface finish and internal structural integrity.
- Strict Quality Control: Every valve undergoes 100% pressure testing and material chemical analysis (spectroscopy) to verify alloy composition.
- Standard Compliance: Fully compliant with API 600, API 603, API 608, and ASME B16.34 for global project compatibility.
Major Application Fields
- General Industry: Steam, water, and gas pipelines.
- Chemical & Petrochemical: Handling corrosive fluids and refined products.
- Food & Beverage: Ensuring hygiene and easy cleaning (Sanitary Grade options available).
- Power Generation: High-temperature and high-pressure water/steam cycles.
