The PVC Ball Valve Double Union Socket Solvent Weld is engineered for plumbers, facilities managers, and serious DIYers who need a valve they can isolate, remove, and reinstall without cutting the pipe — saving time and protecting the surrounding pipework.\u003c\/p\u003e\n    \u003cp\u003eEach valve is constructed from rigid PVC (polyvinyl chloride) with solvent-weld socket ends on both sides. The double-union design means the valve body can be unscrewed from the line unions for maintenance or replacement without disturbing the bonded pipe joints. Available in nine sizes ranging from 20mm (~¾ in) up to 110mm (~4⅓ in), with White and Grey colour options to match your existing pipework or enclosure aesthetic.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include residential and commercial irrigation manifolds, swimming pool and spa bypass circuits, RO and water filtration skids, and chemical dosing lines where periodic valve servicing is expected. The solvent-weld socket connection delivers a permanent, leak-free bond compatible with standard PVC pipe and fittings across all these use cases.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard Schedule 40 \/ Class D PVC pipe.
