Our collection features Double Union Ball Valves, which are highly favoured in koi pond construction because they allow the central valve body to be removed without cutting the surrounding pipework. Constructed from heavy-duty PVC-U, these valves offer a leak-proof seal and smooth operation, making them ideal for both gravity-fed and high-pressure pumped systems.

Product Specifications

Installing high-quality PVC-U Ball Valves is critical for managing the water distribution across your pond. For instance, if you are balancing the return flow to maintain the surface agitation of a 1m² area, these valves provide the fine-tuning necessary to achieve perfect results. At Southcoast Koi and Aquatics, we supply the robust valves needed to build a professional and maintainable koi pond system.
