4" Compact Ball Valve White PVC Threaded (1040WT)

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

The 1040WT introduces the white PVC configuration to the large-diameter compact ball valve series on Maxx-Supply — the first described white PVC compact ball valve at 4-inch, establishing the white PVC product positioning at large diameter that extends the white PVC compact ball valve coverage from the 1-1/2-inch 1015WT and 6-inch 1060WT previously described in the series to the 4-inch size. As established across every white PVC product in the described compact ball valve catalog, white PVC body convention signals potable water compliance, general-purpose water supply service, and irrigation system compatibility — the application contexts where white PVC piping and fittings are the system construction standard and where body color consistency with the surrounding white PVC piping system at isolation valve positions is the correct specification.

The 4-inch white PVC threaded configuration carries the same application context distinction established for the 1040GT gray threaded at 4-inch — at large diameter, threaded NPT connections are more application-specific than socket connections in new PVC system construction, appearing where specific equipment connections, threaded adapter assemblies, or existing threaded system replacement contexts require NPT threading at the 4-inch isolation valve location rather than the socket solvent-weld connection that dominates new construction in-line positions at this size. For white PVC 4-inch applications, the threaded format of the 1040WT is most commonly encountered at large-diameter potable water treatment equipment connections, large water distribution system threaded valve manifold assemblies, municipal water infrastructure threaded connection points, and replacement installations in existing 4-inch white PVC threaded systems — the specific application contexts where 4-inch NPT threading is present at the isolation valve location in white PVC potable water and distribution system infrastructure.

The 1040WT and 1040WS together provide the complete white PVC connection format coverage at 4-inch compact ball valve specification — the 1040WT threaded for the specific application contexts where 4-inch NPT threading is present, and the 1040WS socket for the broader new construction in-line installation context where socket solvent-weld is the dominant connection format throughout new 4-inch white PVC system construction. As with the gray compact ball valve series at 4-inch, the socket 1040WS is the primary new construction specification at 4-inch white PVC in-line positions, and the threaded 1040WT serves the more specific equipment connection and replacement contexts where threading is required at the 4-inch white PVC isolation valve location.

The 1040WT and 1040GT are the white and gray compact threaded ball valve pair at 4-inch — where the 1040GT (gray, threaded) serves the industrial process water, chemical service, and gray PVC system applications where gray body convention confirms industrial service specification, the 1040WT (white, threaded) serves the potable water distribution, municipal water infrastructure, large-scale irrigation, and general-purpose water supply applications where white PVC body convention confirms potable water compliance and general service compatibility. Both are the same compact ball valve design at 4-inch in threaded NPT format — differentiated by body color and the application convention that color represents across the complete PVC valve catalog. Buyers specifying 4-inch compact PVC ball valves on Maxx-Supply should select between 1040WT and 1040GT based on the body color convention of the system being specified — white for potable water and general-purpose water supply systems, gray for industrial and chemical service systems.

White PVC construction at 4-inch delivers the potable water convention consistency, broad chemical resistance across water supply chemistry, and corrosion-free service life that define white PVC compact ball valves for large-diameter potable water distribution, municipal water infrastructure, large-scale irrigation, and general-purpose water supply service environments where the 1040WT provides primary isolation at 4-inch threaded connection positions.

The compact body format at 4-inch white PVC achieves the reduced face-to-face installation dimension that is operationally meaningful at large diameter — fitting in tighter installation spaces than standard-body PVC ball valves at 4-inch in the confined vault, mechanical room, and equipment connection configurations where large-diameter white PVC threaded isolation valves are deployed in potable water and irrigation infrastructure.

Industries & Applications

The 1040WT is the 4-inch threaded white PVC compact ball valve specification for full-port quarter-turn isolation across the large-diameter potable water distribution, municipal water infrastructure, large-scale irrigation, and general-purpose water supply application contexts where 4-inch NPT threaded connections are present at the isolation valve location:

• Municipal Water Distribution — 4-Inch Threaded Main Isolation & Service Connection — Four-inch is a primary main size in municipal water distribution infrastructure where specific threaded connection points at valve manifolds, meter assemblies, pressure reducing valve stations, and service connection assemblies require threaded isolation valves at large-diameter main isolation positions; the 1040WT at 4-inch threaded municipal water distribution isolation positions provides white PVC full-port isolation with potable water body color convention at threaded connection points in municipal water distribution infrastructure where white PVC construction and NSF 61 compliance are the material specification standard for potable water contact.
• Potable Water Treatment — 4-Inch Threaded Equipment Connection Isolation — Four-inch NPT threaded connections at large water treatment equipment — filtration vessels, softener tanks, carbon treatment units, UV disinfection system connections, and large chemical dosing equipment outlet connections — where 4-inch threaded connections are the equipment connection format at the isolation valve location; the 1040WT at 4-inch threaded potable water treatment equipment connection isolation positions provides white PVC full-port isolation with potable water material convention at direct equipment connection isolation points where white PVC construction confirms potable water compliance.
• Large-Scale Irrigation — 4-Inch Threaded Pump Station & Mainline Connection Isolation — Four-inch threaded connection points at large irrigation pump station discharge assemblies, mainline valve manifold assemblies, and primary distribution connection isolation points on large agricultural irrigation, golf course irrigation, and large commercial landscape irrigation systems where 4-inch NPT threading is the connection format at specific primary mainline and pump station isolation positions; white PVC body convention appropriate for the irrigation source water and general agricultural water service chemistry at 4-inch primary mainline threaded isolation positions.
• Replacement — Existing 4-Inch White PVC Threaded Potable Water & Irrigation Systems — Direct replacement isolation valve for existing 4-inch NPT threaded white PVC ball valves and gate valves in potable water distribution, water treatment, and irrigation systems where existing isolation valves at 4-inch white PVC threaded connections require replacement with white PVC compact ball valves matching the existing connection format and body color convention; the 1040WT provides direct threaded replacement in the existing 4-inch NPT white PVC connection format with quarter-turn ball valve isolation as a performance upgrade from legacy multi-turn gate valve configurations in existing 4-inch white PVC threaded potable water and irrigation systems.
