Valterra 3 Piece Gate Valve [2" Slip x 2" Slip] [40 PSI] [Black] (7201) nipples Union style valves are useful because Union style valves are useful because they allow the valve to be serviced or replaced more easily within the plumbing line The SPX0507A1 is a practical replacement for compatible Hayward light assemblies that need renewed trim support and cleaner visual presentation This version is especially useful in solvent welded systems where the darker body is preferred for a cleaner equipment pad appearance and where future maintenance accessibility matters The 3 piece design makes the valve feel like a more deliberate long term plumbing choice rather than a disposable component
