The 179-AC MagnaValve® is a normally closed magnetic valve that supplies ferrous media to shot hoppers. The 179-AC MagnaValve is maintenance free — it has no moving parts so there are no parts to wear or break and it is completely sealed to prevent media dust from entering the valve. The 179-AC MagnaValve has a rare earth permanent magnet for normally closed operation and an electromagnet for controlling shot flow rates. With power applied, the magnetic field is neutralized and shot is allowed to flow through the valve. When no power is applied to the MagnaValve, the permanent magnets stop all flow. If the power is interrupted for any reason, the permanent magnets securely hold the shot, thereby virtually eliminating shot leakage.
