The VLP1000VAR MagnaValve® is a normally closed magnetic valve that regulates the flow of steel shot and grit in wheel blast machines. The VLP1000VAR 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 VLP1000VAR has rare earth permanent magnets 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.
The VLP1000VAR MagnaValve is controlled with a Variac. A Variac is a variable AC transformer that provides 0-120 Vac output voltage to the MagnaValve. With zero volts applied to the MagnaValve, the permanent magnets hold the shot. Application of voltage will cancel the permanent magnets’ holding force and allow the shot to flow. Higher voltages will provide higher shot flow rates. The Variac is included with the VLP1000VAR MagnaValve.
For applications where automatic fault alarms are included, see our model VLP-24 MagnaValve and companion AC-24 Controller at www.electronics-inc.com.
A clear and comprehensive instruction manual simplifies installation of the VLP1000VAR. The MagnaValve is factory tested and results are supplied upon request. In addition, the products are supported by the Electronics Inc. application engineering staff.
