    What the Maric Valve DOES

    The Maric flow control valve is designed to deliver a fixed, pre-set, constant (maximum) flow of water, irrespective of pressure differential across it, (within a given range). In the case of glandwater, this means constant flow rate, irrespective of fluctuating glandwater supply pressure, gland condition, or centrifugal pump discharge pressures. Maric “Flow Control Check” valves, (FCC valves), also offer a reliable backflow prevention feature.

    What the Maric Valve DOES NOT DO

    The flow controller is not designed to control pressure. The flow controller will not allow a flow rate greater than the gland will permit. ie; if the gland is too restrictive, or has been over-tightened.

    Benefits & Why Use a Maric Valve?

    Maric Flow Control valves are used to;
    Protect centrifugal pump glands, through;
    • A constant supply of glandwater to the gland, ensures the life of expensive pump seals are maximized.
    • Prevents one centrifugal pump from robbing all the available glandwater in the event of its failure, which could result in the simultaneous failure of all other glands supplied from the same water supply.
    Prevent unnecessary dilution of slurry, (or liquor in the alumina refining industry) by ensuring that glands cannot receive more than a pre-determined flow rate. A lower than set rated flow is not a particular concern here, as the condition of the gland will ultimately determine flow rate, up to the pre-set maximum permitted by the flow controller. Full rated flow of the flow controller will only result when gland is sufficiently loose enough or worn to enable it. Minimize wastage of available packing water supplies.

    Recommended for Alumina Industry

    Stainless steel flow controllers, fitted with EPDM type control rubber rings are vital for use in alumina refineries due to their caustic and/or high temperature environments. Maric Flow Control Check valves are particularly recommended for the alumina industry, due to the benefit provided by the reliable non-return feature.

    How the Conventional Maric Flow Control Valve Works

    The flow control valves utilize a flexible rubber control ring, with an orifice diameter that responds instantly to fluctuations in water pressure. As pressure differential increases, the orifice diameter reduces to maintain the pre-set flow rate. Likewise, as pressure reduces, the orifice opens up to maintain the pre-set flow rate. These valves are particularly suitable for use on poor water quality, because the flow controlling element is a rubber material, and flexes under normal operation. This minimizes the risk of blockage, and eliminates the build-up of scale.
