Mixproof Valve / Double Seat Valve Description

Mixproof Valve, also known as a Double Seat Valve, is a hygienic flow control solution designed for advanced fluid processing applications. It is widely used in the beverage, dairy, and other sanitary industries, where strict separation of different product streams is essential.

This valve features a high-performance double-seal design, allowing two different fluids to flow through the same valve body simultaneously without risk of cross-contamination. A dedicated leakage chamber with integrated leak detection is located between the two seals. This chamber can be automatically cleaned by the valve seat, ensuring hygienic operation and enhanced process safety.

Key Advantages

Prevents contamination between different product flows.
Ensures product safety with reliable double-seal technology.
Integrated leakage chamber with leak detection for enhanced monitoring.
Self-cleaning design reduces maintenance and supports CIP (Clean-in-Place) processes.
