Specifically designed to bolt directly onto heavy-duty Pentair, PacFab, and Praher 2-inch top-mount and side-mount six-position multiport backwash valves—commonly paired with large Triton® II sand filters and FNS® Plus or Quad D.E.® vertical grid separation tanks—this comprehensive cover module serves as the primary structural anchor for the valve's manual indexing mechanism. Injection-molded from a premium, thick-walled, glass-filled engineering thermoplastic composite, the rugged gray lid features a robust six-bolt perimeter pattern that compresses uniformly over the existing valve body to establish an absolute, leak-proof mechanical seal. This structural barrier safely handles continuous system operating line pressures up to 50 PSI, completely eliminating external water weeping and preventing catastrophic suction-side air induction that would otherwise cause pump cavitation. The assembly arrives factory-equipped with a pre-installed threaded winterization plug, a low-friction handle washer, and a molded upper index track that effortlessly guides the manual lever into its six distinct operational detents (Filter, Backwash, Rinse, Waste, Closed, and Recirculate), providing the essential structural backstop against the valve's internal high-tension compression spring.
