Unique Mixproof Valves


The Alfa Laval Unique Mixproof Large Particle-Flush (LP-F) Valves are adaptable and highly flexible double block-and-bleed valves designed for safe and efficient fluid management at intersection points in matrix piped systems. These valves allow two different products or fluids containing large particles to flow simultaneously through the same valve without any risk of cross-contamination.

With a modular design and a broad range of options, these Alfa Laval Unique Mixproof Large Particle-Flush (LP-F) Valves can be tailored to suit any process requirement. Whether the need is for enhanced cleanability or the ability to endure high pressures. Engineered for gentle handling of products containing large particles up to 1.75″ (45 mm) or those with high viscosity.

Unlike the Alfa Laval Unique Mixproof LP Valves, the Alfa Laval Unique Mixproof LP-F Valves feature a lower flush design, ensuring 100% cleanability of the lip seal in the lower sealing element through seat-lift cleaning alone. It also reduces the need for additional utility installations for external Cleaning-in-Place.
