Description

The LP2000 MagnaValve is a normally closed magnetic valve that regulates the ow of steel shot and grit in wheel

blast machines. The LP2000 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 LP2000 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 LP2000 MagnaValve can be used in “automatic” or “manual” mode. For an automatic closed-loop operation, an

Electronics Inc. AC Controller will detect the current load on the wheel motor and regulate the ow of media to the

LP2000. This closed-loop system will provide accurate and repeatable ow rates over a 400 - 2000 lb/min (181 - 907

kg/min) range. A 102 Power Pack or MC Controller provides “manual” open loop control.

Data sheets available for download at www.electronics-inc.com: AC Controller, MC Controller.

A clear and comprehensive instruction manual simplies installation of the LP2000. The MagnaValve is factory tested

and results are supplied upon request. In addition, the products are supported by the Electronics Inc. application

engineering sta.
