Pentair #320-E-6 White MultiPort Valve Lid

The Pentair #320-E-6 White Multiport Valve Lid (Product #: 273200) is a factory-original OEM replacement top cover plate engineered to maintain absolute structural integrity and pressure sealing on pool and spa sand filtration networks. Specifically designed to fit classic white-bodied Pentair, PacFab, and Praher 1.5-inch side-mount and top-mount multiport backwash valves—commonly installed on residential Sand Dollar® and Tagelus® filters—this heavy-duty lid forms the upper containment barrier for the valve's high-pressure fluid chambers. Injection-molded from a premium, thick-walled engineering thermoplastic composite, the dome features a robust six-bolt perimeter configuration that aligns flawlessly over the existing valve body to compress the main flange gasket. This design ensures total immunity to aggressive pool chemicals, high salt levels, and continuous outdoor weathering, effectively preventing pressure-side water weeping or suction-side air induction under baseline operating pressures up to 50 PSI. The top surface features a molded index track designed to guide the manual selector handle smoothly into its six distinct operational detents (Filter, Backwash, Rinse, Waste, Closed, and Recirculate), providing the essential structural backstop against the high-tension internal compression spring. The physical dry weight of this single Pentair #320-E-6 White Valve Lid is approximately 0.65 pounds (roughly 10.4 ounces, with a packaged shipping weight of approximately 0.85 pounds), delivering a rugged, long-lasting, and vital hardware replacement for efficient pool water management.
