1. PRODUCT DESCRIPTION The 500-24xx Series of MagnaValves are designed to regulate the flow of steel shot or grit in abrasive blast cleaning and shot peening machines. The valves have a magnetic control section (upper portion) and a shot flow rate sensing section (lower portion). Valves are sized by flow rate capacity, either in pounds/minute or in Kg/minute, and are used in air-blast applications such as direct pressure, suction blast or gravity-fed nozzle blast machines.

c. Input Signal – The analog 0-10 Vdc input signal must be above 0.25 Vdc as a minimum flow command signal. For additional information about the MagnaValve consult the FC-24 installation manual. 7. CALIBRATION Calibration of the MagnaValve is done by a catch-and-weigh test. Media is allowed to flow through the valve for a timed period, usually one minute. The shot is weighed and compared to the requested amount. Adjustments are made at the MagnaValve Gain Select switches and adjustment knob.

Zero – turn adjustment until both LED’s are OFF. This will set the output signal to zero ± .050 Vdc during no-flow. Gain – This section controls the amplification or gain of the sensor signal. It has been factory set (see label for flow range). If the gain is changed it will be necessary to run a one minute catch and weigh test to confirm the calibration. The full scale output signal is set to 10 Vdc for kg calibration. Note: be sure only one gain switch is selected (up position).
