Pentair System:2 7.81" Modular D.E. Valve Push Pull

The Pentair System:2 7.81" Modular D.E. Valve Push-Pull Replacement (Product #: 263053) is a factory-original OEM two-position hydraulic slide valve engineered specifically for the distinct plumbing configurations of Sta-Rite® System:2™ modular D.E. (PLDE-series) filters, as well as select System:3® series modular D.E. (SMD-series) and sand (SS-series) filtration vessels. Featuring a specialized 7.81-inch center-to-center bulkhead spacing profile, this heavy-duty slide valve provides an exceptionally streamlined, straight-through fluid dynamic path that dramatically reduces system backpressure compared to traditional 6-position multiport alternatives, letting modern variable-speed pumps sustain peak performance with minimal energy drain. Injection-molded from a premium, thick-walled ABS polymer composite, the rugged valve body delivers total immunity to aggressive pool chemicals, high salt levels, and intense UV exposure under baseline operating lines up to 50 PSI. The valve's ergonomic manual piston handle utilizes a quick-pull structural action to swiftly cycle between standard filtration and full-velocity backwash modes, and it is built with an integrated safety pin that firmly locks the valve into the filter detent to prevent accidental hydraulic shifting. Shipped complete with robust 2-inch PVC slip union connections for direct, tool-free equipment detachment during seasonal winterization or internal grid cleanings, this high-flow manifold ensures robust water circulation management. The physical dry weight of this complete Pentair System:2 7.81" Modular D.E. Valve Push-Pull assembly is approximately 3.8 pounds (with a boxed shipping weight of exactly 4.0 pounds), providing an exceptionally durable, lightweight, and hydraulically optimized fluid-routing solution.
