- Page 3 1. PRODUCT DESCRIPTION The 5xx-24 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 sec- tion (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 applica- tions such as direct pressure, suction blast or gravity-fed nozzle blast machines.

c. For gravity assisted applications (valve located on the top of blast cabinet below the media hopper) an aspiration air inlet must be provided so media can be conveyed to the nozzle. A minimum opening of 12mm is recommended. Do not restrict this air inlet since it will increase the suction and may pull media through the valve. - Page 5 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).
