    Choosing The Correct Settings


    In designing a sprinkler system, a minimum of 20 psi pressure differential (the
    difference between the inlet static pressure and the valve outlet set static
    pressure) is recommended to assure a well regulated and efficient system. In
    choosing the correct setting for the Pressure-Tru valve, refer to the Residual
    Pressure Charts, Static Pressure Chart and the following procedures:
    1.
    Determine the demand in gallons per minute required downstream of the
    valve.
    2.
    Determine the standpipe residual or flow pressure at the valve inlet.
    3.
    Locate the appropriate flow chart based on GPM required and body style.
    4.
    Locate the inlet residual pressure on the vertical axis of the chart and draw a
    horizontal line from this pressure across the chart.
    5.
    Locate the desired valve outlet residual pressure on the horizontal axis of the
    chart and draw a vertical line from this pressure.
    6.
    The curve nearest the intersection of the two lines drawn is the appropriate
    type for the valve.
    7.
    To determine the static outlet pressure, locate the static chart. Determine the
    valve inlet static pressure shown on the vertical axis and draw a horizontal line
    from that pressure to the appropriate curve determined above, then draw a
    vertical line down to the horizontal axis and read the static outlet pressure.

    Maximum Rated Inlet Pressure


    Maximum inlet pressure, to assure a maximum outlet pressure of 175 psi. Inlet side
    of valves can be safely tested up to 400
    PSI during system hydrostatic leak test.

    Proper performance is dependent upon licensed, qualified personnel performing regular, periodic testing according to
    WILKINS specifications and prevailing governmental & industry standards and codes and upon following these installation
    instructions. Failure to do so releases WILKINS of any liability that it might otherwise have with respect to that device. Such
    failure could also result in an improperly functioning device.

    ZW4100 Series Fire Valve


    Part Number Assistant
    Check off the boxes that match the choices you want. If the choice is blank, this is standard and you
    add nothing to the part number. If there are letters after the check box, then you add those letters to the
    part number in that order from left to right.
    A bonnet setting has to be part of the part number since the ZW4100 series valves are factory set and not
    field adjustable. The flow curves Must be used by the system designer to select the correct bonnet setting.
