The W75CP2 Series double seat PMO mix proof valves have been discontinued as of December 2020. The next generation of mix proof valve technology is the result of continued development from both APV and Waukesha Cherry-Burrell process technologies. Used for the reliable separation and continuous processing of dissimilar fluids in Grade A dairies, the D4PMO Series mix proof valves helps fulfill today’s customer demands for production flexibility, high productivity, and enhanced product quality across various applications in the fluid milk, cheese, cream, whey, and yogurt industries.
