As a process engineer with over 15 years at KOSA Valve, I’ve seen firsthand the challenges chemical and petrochemical engineers face with corrosion resistance and fugitive-emission control. Our Flow-Control Valves product line addresses these issues head-on, offering sanitary and industrial control valves, actuation, and flow components designed to meet the stringent demands of high-purity industries.
Material Selection and Corrosion Resistance
Choosing the right material is crucial for corrosion resistance. We predominantly use 316L stainless steel, known for its excellent resistance to a wide range of chemicals. This alloy selection ensures that our valves can withstand harsh environments without degrading over time. For even more demanding applications, we offer valves in exotic alloys like Alloy C-276 and Hastelloy, which provide superior corrosion resistance in highly aggressive media. We also ensure all our products meet ISO 15848 standards for fugitive emissions, a critical factor in maintaining process integrity and safety.
Our valves are designed with corrosion-resistant housings, ensuring longevity and reliability. The 316L stainless steel used in our valves has a minimum tensile strength of 485 MPa and a yield strength of 170 MPa, providing the necessary mechanical integrity for high-pressure applications.
For example, a contract fill-and-finish operation was struggling with valve failures due to corrosion in their acid washing process. Switching to our 316L stainless steel valves with corrosion-resistant housings solved their issue, providing reliable operation and reducing downtime.
Fugitive Emission Control
Fugitive emissions are a significant concern in chemical and petrochemical processes. Our valves are designed to minimize these emissions, adhering strictly to ISO 15848 standards. This ensures that our valves meet the highest standards for leak tightness, helping to maintain process efficiency and safety. We use advanced sealing technologies, including PTFE and elastomeric seals, to achieve leak rates of less than 0.1 mg/m³·h for helium at 50 bar, ensuring compliance with ISO 15848-1 Class B.
Our actuation systems are engineered to provide precise control, reducing the risk of fugitive emissions. We offer a range of actuators, including pneumatic and electric options, tailored to meet specific application requirements. These actuators provide repeatable and reliable performance, ensuring consistent operation and minimal emissions.
Chemical Compatibility
Chemical compatibility is another critical factor in valve selection. Our valves are designed to handle a wide range of chemicals, from acids and bases to solvents and hydrocarbons. We provide detailed chemical compatibility charts for all our materials, ensuring that engineers can select the right valve for their specific application. Our valves are also designed to meet ATEX requirements, ensuring safe operation in explosive atmospheres.
- Acids: Sulfuric, Hydrochloric, Nitric
- Bases: Sodium Hydroxide, Potassium Hydroxide
- Solvents: Methanol, Ethanol, Acetone
- Hydrocarbons: Methane, Ethane, Propane
Standards and Certifications
We adhere to a range of industry standards and certifications to ensure the quality and reliability of our products. Our valves meet ASME BPE 2019 and 3-A Sanitary Standard 2022, ensuring they are suitable for use in food, beverage, and pharmaceutical applications. We also provide valves certified for use in explosive atmospheres, meeting ATEX requirements. This commitment to standards ensures that our valves provide reliable performance in a wide range of applications.
Our valves are manufactured to meet stringent quality control standards, ensuring consistent performance and reliability. We use advanced manufacturing techniques, including CNC machining and precision welding, to ensure the highest quality products. Our quality control processes include 100% inspection of critical dimensions and rigorous testing to ensure compliance with all relevant standards.
Customization and Application Engineering
We understand that each application is unique, and our valves are designed to be customized to meet specific requirements. Our application engineers work closely with customers to understand their needs and provide tailored solutions. We offer a range of customization options, including different materials, sizes, and actuation types, to ensure that our valves meet the specific demands of each application.
Our valves are designed to be easily integrated into existing systems, providing a reliable and efficient solution for flow control. We provide detailed technical documentation and support to ensure that our valves are installed and operated correctly. Our application engineers are available to provide expert advice and support, ensuring that our valves provide reliable performance in a wide range of applications.
For example, a chemical manufacturing plant needed valves that could handle a specific corrosive chemical and operate in an explosive atmosphere. We provided customized valves that met all their requirements, ensuring safe and reliable operation.
