Jobe TOPAZ Automatic Float Valve – High Flow Tank Valve

The Jobe TOPAZ Automatic Float Valve is a robust high-flow float-operated valve designed for automatic water level control in tanks, troughs, cisterns and storage systems. Engineered for reliable performance in agricultural, commercial and industrial applications, the valve uses a pilot-operated diaphragm mechanism that delivers high flow capacity while maintaining stable shut-off with minimal water hammer.

Constructed from corrosion-resistant materials, the TOPAZ valve can be installed in a wide range of mounting positions including side, bottom or top entry. The adjustable float mechanism allows precise level control without tools, making installation and setup simple. With pressure capability from low to high supply systems and a compact durable body, it provides dependable long-term operation in demanding environments.

Designed for versatility, the valve offers adaptable inlet sizes and float options to suit different tank configurations. It is ideal for rainwater harvesting systems, livestock watering troughs, irrigation tanks and general water storage applications where consistent automatic filling is required.
