The Top Half Key Cover and Handle Assembly is a reliable replacement solution for worn or damaged 1-½” top-mount multiport sand filter valves. It restores proper valve rotation, sealing, and positive position control without replacing the entire valve body. This component includes the handle, spring, and upper key cover needed to ensure smooth operation across all filtration and backwash settings. Ideal for common residential sand filters, it helps eliminate leaks, stiffness, and slipping handles while extending the service life of your existing valve.
