    PED Conformity Statement and Information
    The CS400 Product Series is in conformity with the Pressure Equipment Directive PED 97/23/EC.The exception to this previous statement is the Type CS403 which is not yet certified to conform
    with the PED Directive.
    Pressure regulator does not require any supplementary upstream safety accessory for protection against overpressure compared with its design pressure PS, when upstream reducing station is sized for a max downstream incidental MIPd <= 1.1 PS.
    Principle of Operation
    Type CS400 Base Regulator Operation
    Refer to Figure of Fisher CS400 Series When downstream demand decreases, the pressure under the diaphragm increases. This pressure overcomes the regulator setting (which is set by the regulator control spring). Through the action of the pusher post assembly, lever, and valve stem, the valve disk moves closer to the orifice and reduces gas flow. If demand downstream increases, pressure under the diaphragm decreases. Spring force pushes the pusher post assembly downward, the valve disk moves away from the orifice, and the gas flow increases downstream as the regulator opens in response to the decreased pressure underneath the diaphragm.
    The Type CS400IR regulator includes an internal relief valve for overpressure protection. If the downstream pressure exceeds the regulator setting by 7 to 28 inches w.c. / 17 to 69 mbar (depending on the main spring used), the relief valve opens and excess gas is vented through the stabilizer vent in the upper spring case.
    General Installation Instructions
    Before installing the regulator,

    • Check for damage, which might have occurred during shipment.
    • Check for and remove any dirt or foreign material, which may have accumulated in the regulator body.
    • Blow out any debris, dirt or copper sulfate in the copper tubing and the pipeline.
    • Apply pipe compound to the male threads of the pipe before installing the regulator.
    • Make sure gas flow through the regulator is in the same direction as the arrow on the body. “Inlet” and “Outlet” connections are clearly marked.
    • When designing a pressure reducing station using a CS400 Series regulator, make an analysis if it is necessary to take into account the effects of wind, snow, and temperature to avoid unnecessary load and movement to the flanges of the equipment.

    Installation Location
    The installed regulator should be adequately protected from vehicular traffic and damage from other external sources.
