FAQs: Alfa Laval Unique SSV Two Step Valve
What is the function of a two step valve in hygienic applications?
The Alfa Laval Unique SSV Two Step Valve enables precise two-stage filling, dosing, and simultaneous drainage. It helps reduce waste and improve filling accuracy, particularly in industries like dairy, food, beverage and pharmaceuticals.
Is the Unique SSV Two Step Valve suitable for CIP processes?
Yes. The valve is designed with FDA-approved elastomers, full drain ability and smooth, crevice-free surfaces, making it ideal for Cleaning-in-Place (CIP) systems in hygienic production.
How does the intermediate valve position work?
This feature allows the valve to open partially for low-flow applications like dosing or controlled filling. It minimizes pressure surges and ensures better process control when paired with Alfa Laval ThinkTop control units.
Comparison Table: Two Step Valve vs Traditional Single Seat Valve
| Feature | Alfa Laval Two Step Valve | Standard Single Seat Valve |
|---|
| Filling Accuracy | Two-stage operation allows precise dosing | Limited control, no intermediate positioning |
| Cleaning Compatibility | Fully CIP and SIP compliant | CIP-compatible but may have more dead zones |
| Hygienic Certification | EHEDG, FDA, 3-A compliant | May vary by manufacturer |
| Design Flexibility | Modular with adjustable lift, multiple ports | Typically single-function |
| Control Integration | Compatible with ThinkTop V50/V70 for advanced control | May support basic sensors only |
SS Two Step Valve Operating Principle
The Alfa Laval SS Two Step Valve is pneumatically operated via compressed air, typically controlled remotely for convenience. Smooth actuator operation provides precise control, while the valve’s intermediate positioning capability reduces pressure shocks during filling or dosing processes. Using an Alfa Laval ThinkTop control unit enhances operational precision, ensuring accurate and safe process control.
For standard applications, the valve includes two working ports for air supply. In changeover applications, a third port is added to manage process air effectively.
The Unique SSV Two Step Valve is available in both one-body and two-body configurations, designed for simple integration into existing systems. The valve body, plug, actuator and clamp rings are easily configurable to specific applications. It functions efficiently as a shut-off valve with two or three working ports or as a changeover valve with up to five ports, enabling simultaneous drainage or filling operations.
Valve seats, positioned between two bodies in the changeover configuration, ensure a tight, reliable seal. All valve seals are precisely engineered to ensure longevity and robust performance under repeated operation. Actuators connect to valve bodies via robust clamp rings and intermediate valve opening can be precisely adjusted using internal spacer rings.
The Alfa Laval Unique SSV Two Step Valve can also integrate seamlessly with Alfa Laval ThinkTop V50 and V70 control units, allowing for accurate sensing and control.
