Pentair 2" Top Mount Multiport Valve

The Pentair 2" Top-Mount Hi-Flow™ Multiport Valve (Product #: 263085 / 261185) is a commercial-grade water routing manifold engineered to deliver superior fluid dynamics and high-capacity operational control for top-mount pool and spa sand filtration systems. Specifically designed as a direct-fit companion for heavy-duty top-mount filtration vessels—such as the Pentair Tagelus® TA60/TA100D and Sand Dollar® SD80 series—this rugged component utilizes a large 2-inch internal flow profile that significantly minimizes friction loss and backpressure, allowing modern variable-speed circulation pumps to run at energy-saving lower speeds.

Injection-molded from a thick-walled, ultra-high-impact ABS polymer composite, the robust valve housing features a secure clamp-style mounting configuration (designed for 6-inch or 8-inch tank neck sizes) that locks tightly over the upper filter flange to form an absolute, leak-proof seal. Its ergonomic, one-piece manual lever handles a heavy-tension internal spring that allows operators to seamlessly index through six distinct hydraulic modes—Filter, Backwash, Rinse, Waste, Closed, and Recirculate—along with a dedicated winterization detent to protect the internal diverter assembly from freezing damage during the off-season. Built to easily manage baseline hydraulic surges and high-velocity circulation loads at operating system pressures up to 50 PSI, the assembly includes a pre-seated rubber spider gasket that guarantees absolute isolation between flow chambers to eliminate waste line weeping. The physical dry weight of this complete Pentair 2" Top-Mount Multiport Valve is approximately 8.05 pounds (with a packaged carton shipping weight of roughly 9.23 pounds), providing an exceptionally durable, reliable, and hydraulically optimized fluid-management centerpiece for pristine pool water quality.
