1-1/2" Compact Ball Valve Gray PVC Threaded (1015GT)

The 1015GT is a 1-1/2-inch compact gray PVC ball valve with threaded NPT end connections — a full-port, quarter-turn isolation valve engineered for the industrial, chemical process, water treatment, and commercial mechanical isolation applications where corrosion-free gray PVC construction, compact body format, and threaded NPT end connections at 1-1/2-inch diameter define the correct isolation valve specification across the broadest combined industrial and commercial buyer base in the medium-diameter gray PVC compact ball valve size range.

The 1015GT introduces the 1-1/2-inch size to the compact gray PVC threaded ball valve series on Maxx-Supply — extending the described series below the 2-inch 1020GT into the medium-diameter range where 1-1/2-inch threaded gray PVC ball valves serve as primary isolation valves on chemical processing secondary headers, water treatment plant chemical feed branch lines, industrial process water distribution branches, HVAC hydronic secondary distribution, and individual equipment supply isolation connections across the full range of industrial and commercial applications where gray PVC construction, threaded NPT connections, and compact ball valve format define the correct isolation specification at this diameter.

The 1-1/2-inch position in the compact gray PVC series mirrors the position the 1-1/2-inch size holds across every other valve and fitting family in the Maxx-Supply catalog — one of the highest-frequency individual valve sizes across the combined commercial and industrial application base, appearing at secondary distribution headers, zone supply connections, equipment supply mains, and secondary process line isolation points in the commercial building, industrial process, water treatment, and HVAC system types that define the gray PVC compact ball valve buyer universe. At 1-1/2-inch, the gray PVC compact ball valve serves the secondary distribution and equipment supply connection tier of industrial and chemical systems — the pipe size immediately below the 2-inch primary process line tier that is served by the 1020GT — providing isolation at the branch connections, equipment supply lines, and secondary distribution points that feed from 2-inch and larger primary headers to the individual equipment connections and terminal isolation points of the system.

The 1015GT and the 1015WT — the gray and white compact ball valve pair at 1-1/2-inch described in the Maxx-Supply valve catalog — represent the complete 1-1/2-inch compact PVC ball valve color specification at this diameter. Where the 1015WT (white, threaded) serves potable water, irrigation, and general-purpose water supply applications where white PVC body convention signals potable water compliance and general service compatibility, the 1015GT (gray, threaded) serves industrial process water, chemical service, and gray PVC system applications where gray body convention signals industrial service specification and chemical system compatibility. The two valves are the same compact ball valve design at 1-1/2-inch in threaded NPT format — differentiated by body color and the application convention that body color represents across the PVC valve catalog. Buyers specifying 1-1/2-inch compact PVC ball valves on Maxx-Supply should select between 1015GT and 1015WT based on the body color convention of the system they are specifying — gray for industrial and chemical service PVC systems, white for potable water and general-purpose water supply systems — with the understanding that both valves deliver the same compact ball valve performance at 1-1/2-inch threaded NPT.

The threaded NPT end connections at 1-1/2-inch are the most widely applicable connection format for the gray PVC compact ball valve at this diameter — 1-1/2-inch NPT is the standard connection format across the full range of medium-diameter industrial process equipment connections, pump body connections, chemical storage outlet connections, instrument manifold connections, and individual system isolation points where 1-1/2-inch threaded gray PVC ball valves are specified in the highest volume across the industrial and commercial buyer base. At 1-1/2-inch, threaded NPT connections are encountered routinely in both new system construction and existing system replacement — making the 1015GT threaded format broadly applicable across a wide range of installation contexts including new industrial equipment connections, replacement valve installations in existing threaded systems, and adapter connections between PVC systems and metallic equipment throughout the 1-1/2-inch gray PVC compact ball valve application profile.

The companion relationship between the 1015GT (gray threaded) and the 1015GS (gray socket) provides complete end-connection format coverage at 1-1/2-inch gray compact ball valve specification — threaded for equipment connections, instrument manifolds, existing threaded system replacement, and adapter assemblies; socket for new gray PVC solvent-weld system construction. At 1-1/2-inch, both the threaded and socket configurations serve active and high-volume application contexts across the industrial and commercial gray PVC ball valve buyer base — consistent with the 2-inch size where both connection formats are fully standard and routinely specified at equivalent application frequency.

Gray PVC construction at 1-1/2-inch delivers the chemical resistance, industrial service convention, and corrosion-free service life that define gray PVC compact ball valves for the chemical processing, industrial process water, and water treatment plant service environments where the 1015GT is most commonly deployed at secondary distribution and equipment supply isolation positions.

Industries & Applications

The 1015GT is the 1-1/2-inch threaded gray PVC compact ball valve specification for full-port quarter-turn isolation across the industrial, chemical, water treatment, and commercial mechanical applications where 1-1/2-inch NPT threaded connections and gray PVC construction define the correct isolation specification:
