TOPAZ DIFFERENTIAL Product Info Description Topaz Differential valves are ideal for use in water tanks which are filled by a pressure system controlled water pump. The valve gives a level difference which is adjustable from 50mm up to 2.5m to minimise starting and stopping of the pumping system. Maintaining Water Levels in: • Water Storage Tanks • Water Cisterns • Irrigation Applications • The valve mounts at the top of the tank. It fits easily through a thin walled tank or screws into a threaded tank inlet. Flow Graph Gallons/Minute • As the tank empties the weighted float travels down the cord until it hits the bottom stop. The valve then opens immediately to give a full flow. Valve Inlet Pressure The valve now runs constantly and the weighted float rises until it hits the upper float stop. This lifts the arm and the valve shuts down. Observe the pressure that your pump runs at while the tank is filling. Set the pressure switch to turn the pump off at a pressure at least one bar above the running pressure. Features • High flow • Start and stop levels can be easily adjusted to give water level differentials from 50mm to 2.5 m • Keeps pump operation to a mininum. • DetachTM Valve Seal Access System for quick access to valve seal (Patented) • Ideal for all makes and models of tanks.
