Overview / Why Choose This Product

Its slow, controlled opening and closing—combined with a built‑in reservoir tube (baffle)—delivers quiet operation and confidence in tight installations like toilet cisterns and evaporative air conditioners. BSP threads ensure easy compatibility across plumbing systems, and the robust thermoplastic construction offers long‑term corrosion resistance. Australian Made design and testing underpin reliability in local conditions.
