[Music] the Alfa Laval unique mixed proof valve is a double block and bleed valve that provides maximum flexibility and safety for sanitary flow processing it handles two different fluids at the same time with absolutely no risk of cross-contamination this means that a single mix proof valve most often replaces two or more valves of other types the modular concept behind unique mix proof valves means you pay only for the exact features and capabilities you need this gives you rapid payback and maximum return on investment the concept also enables easy upgrades with additional features and functionalities should your needs change this ensures you have exceptional flexibility in designing your processing installation defined metal-to-metal movement low wear and seals and no adjustable parts ensure reliable state-of-the-art operation of the actuator as an option the actuator can be equipped with seat lifts or seat push functions this helps speed the cleaning operations and supports minimal utilities consumption in addition the actuator is maintenance friendly thanks to its straightforward design cage spring and simple seal arrangement for easy dismantling and fast maintenance the valve body features a top loaded design and clamps for easy decembe lee and reassembly built-in leak detection defined compression of static seals and double-acting lip seal technology eliminate the risk of product contamination two independent plugs each with one seal create a hygienic double block and bleed design the lower plug features a guided and protected radial seal which provides long-lasting operation as an option both the upper and lower plugs can be supplied fully balanced to enhance performance and ensure that the mix proof security and excellent hygiene capabilities of the valve are not jeopardized in the event of pressure shocks in the process pipe fitting unique mix proof valves with the effective spiral clean system for the plugs and leakage chamber is yet another option spiral clean provides faster and more effective cleaning even under difficult conditions while using less cleaning fluid utilities and time the Alfa Laval unique mix proof valve which can be fitted with any level of sensing and control is designed to provide the lowest possible cost of ownership throughout its exceptional service life this results from a combination of design simplicity low maintenance costs and minimal utilities consumption repair is easy and only requires a few simple tools simplified construction straightforward maintenance and reduced water consumption contribute to maximum uptime and minimum cost of ownership it is completely safe to clean the upper valve body and the upper plug seal of an Alfa Laval unique mix proof valve while product is flowing through the lower section of the valve body the fast-acting seat lift for cleaning the upper plug seal always creates a throttling edge due to the defined metal-to-metal stop in the actuator this speeds up the cleaning process by creating high turbulence and scrubbing effects making very efficient use of a minimal amount of CIP fluid it also reduces pressure of the CIP fluid eliminating the risk of pressure buildup in the leakage chamber and ensuring risk-free cleaning the design of unique mix proof valves enables different products to flow through each section of the valve bodies without any risk of cross-contamination like the seat lift operation the fast-acting seat push function is controlled by a defined metal-to-metal opening which provides a throttling edge this speeds up the cleaning process by creating high turbulence and scrubbing effects thereby making very efficient use of minimal CIP fluid it also reduces pressure of the CIP fluid and promotes risk-free cleaning because there is no risk of pressure buildup in the leakage chamber it is important to adjust the duration of a seat lift or seat push operation to match the requirements of the process and product if necessary multiple seat lift operations can be performed with the unique mix proof valve you get double block and bleed functionality in one compact valve in the event of plug seal failure leakage will be visible at the bottom of the valve opening the valve is a two-step movement first the actuator retracts the lower plug pulling it into the upper plug then it continues to lift both plugs into the fully open position closing the valve is also a two-step movement first the upper plug moves into the axial seat then the lower plug with its radial seal is guided into position providing long-lasting operation [Music]
