Ball Valves

Take full control of your pond circulation and simplify equipment maintenance with our range of high-performance PVC-U ball valves and double union isolation valves. Engineered specifically for demanding aquatic plumbing systems, professional-grade ball valves provide leak-proof flow regulation, precise manifold balancing, and effortless equipment isolation across pump delivery lines, UV clarifier bypass circuits, and waste lines.

Our collection features heavy-duty imperial and metric double union ball valves manufactured from tough, fish-safe PVC-U. Designed with true union threaded collars at both ends, these valves allow you to easily uncouple inline pumps, filtration units, or pipe runs for servicing without having to cut into existing solvent-welded pipework. Each valve features smooth PTFE seats and durable EPDM O-ring seals to ensure an airtight, watertight seal under constant hydrostatic pressure, while the ergonomic quarter-turn handle delivers smooth, non-stick operation even after extended use. Available in standard plumbing sizes ranging from 1.5 inch and 2 inch for pump returns up to 3 inch and 4 inch for high-flow gravity lines, explore our full ball valves collection to find dependable, builder-approved flow control components engineered for lasting durability.
