Hayward Pro Series Vari-Flo 2-Inch Multiport Control Valve Kit — Black, Top-Mount OEM Replacement (Includes Clamp & O‑Ring)

Hayward's Pro Series Vari-Flo 2-inch control valve (SP071620T) is a direct replacement top-mount multiport valve engineered to restore reliable flow control and filtration to compatible Hayward sand filter models.

This OEM replacement valve is built for Hayward Pro Series top-mount sand filters and provides the multi-function control you need for filtering, backwashing, rinsing, and more. Supplied as a kit, it includes the Vari-Flo multiport valve assembly plus the clamp and O-ring needed for secure installation. The 2-inch pipe size suits standard residential and light-commercial plumbing on the matching Hayward S-series filters.

Which Hayward sand filters are compatible with this control valve?

The SP071620T is designed specifically for Hayward Pro Series top-mount sand filter models including S270T2, S310T2, and S360T2. If your filter is one of these models, this valve matches the original equipment specifications and mounting pattern. Always confirm your filter model and pipe size before ordering.

• Compatible models: S270T2, S310T2, S360T2
• Pipe connection: 2-inch standard plumbing
• Mounting: top-mount multiport replacement pattern

What parts are included and what will I need for installation?

The kit ships with the Vari-Flo multiport valve (equivalent to SP071621), a clamp (GMX600NM), and an O-ring (GMX600F). These components allow you to swap the valve assembly onto the top of the filter without sourcing aftermarket fittings. You will need basic hand tools and follow the filter manufacturer’s installation guidance for a safe, watertight fit.

• Included: Vari-Flo valve, clamp, and O-ring
• Installation tools: screwdriver, pliers, possibly lubricant for O-ring
• Tip: depressurize the filter and follow Hayward instructions for valve alignment

How does this Vari-Flo valve improve filter operation?

The multiport valve restores the full range of filter functions — filter, backwash, rinse, waste, closed, and recirculate — allowing effective cleaning and water handling. Its 2-inch passage supports typical pool pump flow rates used with the Pro Series sand filters, helping maintain consistent performance when matched to the correct filter model. Using the correct OEM replacement helps prevent leaks and operational problems related to mismatched valves.

• Restores full multiport functionality (filter/backwash/rinse etc.)
• 2-inch bore suitable for recommended flow rates
• OEM-fit minimizes risk of leaks and misalignment

Is this a direct OEM replacement and what about durability?

Yes — this is an OEM Hayward Pro Series replacement valve intended to match original equipment fit and function. The included clamp and O-ring are sized for the Pro Series top-mount assembly to ensure a secure seal. Built for pool equipment use, the valve components are engineered to withstand normal seasonal operation when installed and maintained according to Hayward guidelines.

• OEM replacement: designed to match original specifications
• Includes clamp and O-ring for sealed connection
• Constructed for routine pool filtration environments

Who this is for: Pool owners and service technicians who operate Hayward Pro Series top-mount sand filters (S270T2, S310T2, S360T2) and need a reliable, OEM-grade multiport valve replacement. Choose this kit when your existing valve shows leaks, broken handles, or fails to switch functions properly. If your filter model and 2-inch plumbing match, this part restores original control and reduces the chance of installation complications associated with aftermarket mismatches.
