Food & Dairy Flow-Control Valves for KOSA Filter: precise, leak-tight control with 316L stainless steel

Ensuring Hygienic and Reliable Flow Control in Food, Beverage, and Dairy Processing

As a process engineer with 15 years at KOSA Filter, I've seen firsthand how critical reliable, hygienic flow control is in food, beverage, and dairy processing. Our Flow-Control Valves product line meets these demands, ensuring sanitation, cleanability, and low risk of contamination. Let's dive into the specifics of why and how our valves stand out in this industry.

Materials and Construction for Hygienic Design

Our valves are constructed from 316L stainless steel, chosen for its excellent corrosion resistance and compatibility with a wide range of chemicals used in CIP (Clean-In-Place) systems. All product contact surfaces are polished to a 32Ra or better finish, meeting 3-A Sanitary Standard 2022 requirements. This polish minimizes surface roughness, reducing the risk of bacterial adhesion and making the valves easier to clean. The use of hygienic housing designs with smooth, crevice-free surfaces further supports easy cleaning and inspection.

For gaskets and seals, we use FDA-compliant materials that meet USDA and EHEDG guidelines. These materials ensure low extractables and minimal risk of contamination. In critical applications, we offer diaphragms with <1 ppb extractables, providing peace of mind for sensitive processes.

Design for Cleanability and Hygiene

Our valves are designed with cleanability in mind. We incorporate features like self-draining cavities and sloped surfaces to prevent fluid traps and ensure complete drainage. All valves are fully CIP-able, allowing for efficient and effective cleaning. We also offer options for steam-in-place (SIP) capabilities, enabling sterilization without disassembly. This is crucial for maintaining hygiene and reducing downtime in food and dairy processing.

Actuation and Control for Precision and Reliability

We offer a range of actuation options, from manual to pneumatic and electric actuators. Each is designed to provide precise control and reliable operation. Pneumatic actuators are commonly used in food processing due to their explosion-proof capabilities and suitability for hazardous environments. Electric actuators offer precise control and are ideal for applications requiring frequent adjustments.

Our actuation systems are designed to withstand the harsh conditions of food processing environments. They are constructed with stainless steel housings and food-grade lubricants, ensuring durability and compliance with food safety regulations. Additionally, we offer intelligent actuation systems with integrated sensors and control features, providing real-time monitoring and data logging for enhanced process control and traceability.

Meeting Industry Standards and Regulations

Our Flow-Control Valves are designed and manufactured to meet stringent industry standards and regulations. We comply with 3-A Sanitary Standards, EHEDG guidelines, and USDA requirements, ensuring our valves meet the highest hygienic standards. All our products are manufactured in accordance with ASME BPE 2019, guaranteeing consistent quality and performance. We also offer certificates of compliance and detailed documentation to support validation efforts.

Application Example: Contract Filler Case Study

One of our contract filler clients struggled with frequent product contamination due to inadequate valve design. Their existing valves had poor cleanability and were prone to bacterial build-up. We replaced these with our hygienic flow-control valves, featuring self-draining designs and CIP capabilities. The result? A significant reduction in contamination events and improved product quality, leading to enhanced customer satisfaction and reduced waste.
