Description

The VLP1000/VAR MagnaValve is a normally closed magnetic valve that regulates the ow of steel shot and grit in wheel

blast machines. The VLP1000/VAR 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 VLP1000/VAR has rare earth permanent magnets for normally closed operation and an electromagnet for controlling

shot ow rates. With power applied, the magnetic eld is neutralized and shot is allowed to ow through the valve. When

no power is applied to the MagnaValve, the permanent magnets stop all ow. If the power is interrupted for any reason,

the permanent magnets securely hold the shot, thereby virtually eliminating shot leakage.

The VLP1000/VAR 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 ow. Higher voltages will provide higer shot ow rates. The Variac is included with the VLP1000/

VAR MagnaValve.

The VLP1000/VAR MagnaValve provides a high degree of media control but it will not recognize fault conditions

such as low ow rates. Visit the Electronics Inc. website for other valve series which work with the AC amperage

controller (www.electronics-inc.com/magnavalve_selector_guide_for_wheel_blast_machines.html). The AC

Controller has a large digital display of motor amps and high/low alarms.

A clear and comprehensive instruction manual simplies installation of the VLP1000/VAR. The MagnaValve is

factory tested and results are supplied upon request. In addition, the products are supported by the Electronics

Inc. application engineering sta.
