Jobe TOPAZ Dual Level Differential Float Valve – Pump Control Valve

The Jobe TOPAZ Dual Level Differential Float Valve is a high-flow automatic tank valve specifically designed for water storage systems supplied by pressure pumps. It provides precise dual-level control, allowing the tank water level to drop to a preset lower point before refilling begins, then shutting off at an upper level once the tank is full. This differential operation reduces rapid pump cycling, improving pump efficiency and extending equipment life.

Engineered for reliable performance in demanding applications, the valve uses a weighted float on a cord with adjustable upper and lower stops to control water levels. As the water level falls, the float descends to the lower stop, opening the valve for full flow. During refilling, the float rises to the upper stop, closing the valve and stopping inflow automatically. The valve mounts at the top of the tank and fits through thin-walled tanks or threaded inlets for easy installation.

Designed for durability and consistent operation, the TOPAZ differential valve supports high flow rates and a wide pressure range, making it suitable for large tanks, irrigation systems, cisterns, and pump-fed storage applications. The adjustable differential range typically spans from approximately 50 mm up to 2.5 metres, allowing flexible control for various tank sizes and operational requirements.
