The Madic Pressure Regulator Valve is used in the line between the Aboveground Storage Tank and the Pump. The valve must be installed horizontally and as near to the pump as possible. The maximum flow rate is 83 litres per minute and the valve cannot be used for a liquid head above 6m. The valve can also be supplied as an assembly which includes a Shear Valve to ensure no product is lost in the event of a pump knock over.
