4" Compact Ball Valve White PVC Socket (1040WS)

The 1040WS is a 4-inch compact white PVC ball valve with socket end connections — a full-port, quarter-turn isolation valve engineered for permanent solvent-weld installation in the large-diameter potable water distribution, municipal water infrastructure, large-scale irrigation, and general-purpose water supply systems where white PVC body convention, corrosion-free construction, compact body format, and socket solvent-weld end connections at 4-inch diameter define the correct large-diameter in-line isolation valve specification for the potable water, irrigation, and general service system environments the 1040WS serves.

The 1040WS is the socket-end companion to the 1040WT — the threaded NPT configuration in the same 4-inch compact white PVC ball valve format described earlier in the series. As established across every socket-end description in the described compact PVC ball valve catalog, the socket configuration is the correct specification for new white PVC system construction in-line positions — the format that installs directly into the solvent-welded white PVC piping run at the isolation valve location as a permanent bonded component of the system — while the threaded companion (1040WT) serves the more specific equipment connection and existing threaded system replacement contexts where 4-inch NPT threading is present at the white PVC isolation valve location.

The 1040WS and 1040WT together complete the white PVC configuration pair at 4-inch compact ball valve specification — the 1040WS socket for the primary new construction in-line isolation context throughout new 4-inch white PVC system construction, and the 1040WT threaded for the specific equipment connection and replacement contexts where threading is the connection format at the 4-inch white PVC isolation valve location. As established for the gray PVC 4-inch pair (1040GS socket and 1040GT threaded), socket is strongly dominant for new construction in-line positions at 4-inch — large-diameter 4-inch piping in new white PVC system construction is overwhelmingly socket-connected throughout, with every fitting, tee, elbow, and reducer in the 4-inch white PVC piping run installed by socket solvent-weld, and in-line isolation valves at 4-inch in-line positions following the same socket construction method as every other component in the large-diameter run.

The 1040WS is the white PVC counterpart to the 1040GS — where the 1040GS serves in-line socket isolation positions in gray PVC industrial and chemical large-diameter system construction, the 1040WS serves in-line socket isolation positions in white PVC large-diameter potable water distribution, municipal water infrastructure, large-scale irrigation, and general-purpose water supply system construction. Both are the same compact ball valve design at 4-inch in socket format — differentiated by body color and the application convention that color represents: white for potable water compliance, NSF-compliant service, and general water supply convention; gray for industrial service, chemical handling, and gray PVC system convention. Buyers specifying 4-inch compact socket PVC ball valves on Maxx-Supply select between 1040WS and 1040GS based on the body color convention of the system being constructed — white for potable water and general-purpose water supply systems, gray for industrial and chemical service systems.

At 4-inch in the white PVC socket configuration, the large-diameter threshold established for the 1040GS applies equally to the 1040WS — the size where compact body format, corrosion-free PVC construction, and permanent socket bond integrity deliver their most operationally significant combined advantages over metallic alternatives in large-diameter potable water and irrigation isolation service. White PVC compact ball valves at 4-inch are meaningfully lighter than metallic alternatives at large diameter, install with the same primer and solvent cement method used throughout the new construction 4-inch white PVC system, and deliver corrosion-free service life appropriate for the continuous potable water and irrigation source water contact service conditions at large-diameter primary distribution and mainline isolation positions.

The application profile of the 1040WS at 4-inch new white PVC socket construction spans the large-diameter primary distribution tier of municipal water systems, large commercial building primary supply, large-scale irrigation primary mainline, and industrial process water white PVC primary distribution — the in-line positions at primary main isolation, major branch isolation, pump station discharge and suction at the large-diameter primary distribution tier of new white PVC system construction where socket-connected in-line isolation valve installation is the standard construction method at every in-line isolation position throughout the 4-inch new white PVC piping system.

The replacement context at 4-inch white PVC socket spans large-diameter in-line socket-connected isolation valve replacement in existing municipal water distribution, large commercial building supply, and large irrigation systems where socket-connected 4-inch white PVC in-line isolation valves have reached end of service life — cut out, replace with the 1040WS using short pipe spools or union arrangement, restoring socket-connected in-line isolation at the 4-inch primary distribution position without converting the connection format.

White PVC construction at 4-inch delivers the potable water convention consistency, NSF-compliant material specification, and corrosion-free service life appropriate for the large-diameter primary distribution, municipal water infrastructure, large irrigation mainline, and general-purpose large-diameter water supply service environments where the 1040WS provides permanent socket-bonded in-line isolation at the large-diameter primary distribution tier of new white PVC system construction.
