The Model 577-24 MagnaValve is a normally closed magnetic valve suitable for 
regulation of steel shot and includes a built-in sensor for accurate measurement of flow 
rate. Used with the Model FC-24 Shot Flow Controller, the MagnaValve will provide 
accurate and repeatable flow rates over a 1 - 10 pounds-per-minute flow range. The 
577-24 MagnaValve can be re-calibrated for various shot types and sizes for higher 
accuracy. 
The valve construction includes a permanent magnet for normally closed operation 
and an electromagnet for controlling shot flow rates. By regulating the voltage to the 
electromagnet, any desired flow rate may be achieved. When power is off, the valve 
will hold shot due to the permanent magnet. 
The Model 577-24 MagnaValve incorporates a preamplifier circuit to allow for high 
noise immunity and a 0-10 Vdc output. The valve is factory calibrated and results are 
included upon request. Note: consult factory for pre-calibration using media other than 
cast steel shot.
