Features
- Flow rate range of 200 – 1000 lb/min (91 – 453 kg/min)*
- Flow control for wheels up to 25 Hp (19 kw)
- Regulates flow of steel shot and grit
- Normally closed
- No moving parts for low-maintenance operation
- Easy retrofit installation* Flow rate depends on media type
The VLP1000 MagnaValve® is a normally closed magnetic valve that regulates the flow of steel shot and grit in wheel blast machines. The VLP1000 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 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 VLP1000 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 flow of media to the VLP1000. This closed-loop system will provide accurate and repeatable flow rates over a 200 – 1000 lb/min (91 – 453 kg/min) range. A 102 Power Pak or MC Controller provides “manual” open loop control.
A clear and comprehensive instruction manual simplifies installation of the VLP1000. The MagnaValve is factory tested and results are supplied upon request. In addition, the products are supported by the Electronics Inc. application engineering staff.
