Mixproof Valve Manifolds
A mix proof valve manifold is a tight cluster of automated system of integrated mix proof valves on a supporting frame. Utilities like compressed air, I/O are consolidated into a single area. Liquid hold-up volumes are minimized. Mixproof valves that safely and efficiently route multiple products and cleaning streams in a production line, preventing cross-contamination between incompatible fluids while allowing simultaneous processing and cleaning operations. These systems are vital in hygienic industries, such as food and beverage, dairy, and pharmaceutical manufacturing, for maintaining product integrity, optimizing production time, and ensuring compliance with strict hygiene standards.
How Mixproof Valve Manifolds Work:
- Automated Fluid Control: The system uses automated valves to control the flow of different liquids, acting like a “traffic cop” to direct them to their intended destinations.
- Prevention of Cross-Contamination: By using a double-valve system, product and cleaning solutions are kept separate. The valves are designed to prevent mixing of incompatible fluids, even during simultaneous operations like filling one tank while cleaning another.
- Simultaneous Operations: A single manifold can handle multiple processes at once, such as filling and emptying different tanks, while also performing a clean-in-place (CIP) cycle on another line without interruption.
- Centralized Control: The entire system can be controlled remotely via a PLC (Programmable Logic Controller) and may include integrated sensors, solenoids, and a fieldbus interface for status display and operation.
Key
Benefits:
- Enhanced Productivity: By enabling simultaneous production and cleaning, Mixproof Valves reduce cleaning and downtime, increasing production time and revenue. Mixproof manifolds significantly increase production reliability and repeatability, reduce downtime and maximize production capacity.
- Engineering Support: Holland Engineers can design the process P&ID for the valves, design and fabricate the complete manifold weldment. An Approval Drawing Process is used to ensure the finished product reflects your needs.
- Improved Safety & Hygiene: The elimination of cross-contamination is crucial for maintaining the safety and quality of products, especially in food, dairy, and pharmaceutical applications.
- Increased Flexibility: Mixproof valve manifolds allow for flexible process management, allowing for easy changes in production routes and sequences.
- Automation: The system provides a safe, flexible, and automated alternative to manual hose systems, improving efficiency and reducing manual labor.
Common
Applications:
