Pentair 2" Sta-Rite® Side Mount MultiPort Valve Spring

The Pentair 2" Sta-Rite® Side-Mount Multiport Valve Spring (Product #: 14965-0005) is a factory-original OEM replacement internal tension component engineered to provide robust mechanical resistance and precise seating control within high-capacity pool and spa filtration networks. Specifically designed to sit within the upper dome assembly of Sta-Rite® 2-inch side-mount six-position multiport backwash valves—which are commonly paired with premium System:2™ and System:3® series modular sand and diatomaceous earth (D.E.) separation vessels—this heavy-duty compression spring serves as the mechanical force that drives the internal diverter rotor down against the rubber spider gasket. When an operator depresses the exterior manual lever handle to index between dynamic hydraulic cycles (such as Filter, Backwash, Rinse, and Waste), the spring absorbs the physical thrust and instantly snaps the internal sealing disc back into its locked position upon release. Forged from high-tensile, marine-grade stainless steel alloy, its resilient coil architecture delivers outstanding fatigue resistance and complete immunity to systemic rust, continuous pump room humidity, and concentrated pool sanitation chemicals like chlorine or salt shock, preventing the valve handle from sagging, sticking, or causing internal fluid cross-contamination under operational pressures up to 50 PSI. The physical dry weight of this single Pentair Sta-Rite Valve Spring is approximately 0.40 pounds (roughly 6.40 ounces, with a nominal packaged shipping weight of up to 0.55 pounds depending on specific retail box cushioning), providing pool service professionals and DIY homeowners with a rugged, highly reliable hardware standard to maintain peak filtration efficiency and effortless lever operation.
