The MagnaValve® is a normally closed magnetic valve that regulates the flow of steel shot and cut wire media in air blast machines. The MagnaValve’s built-in sensor measures flow rate and, together with the FC Controller (sold separately), provides accurate and repeatable flow rates. The MagnaValve can be factory calibrated for various media types and sizes.

The MagnaValve’s construction includes a strong and stable rare earth permanent magnet for normally closed operation and an electromagnet for controlling shot flow rates. When no power is applied to the MagnaValve, the permanent magnet stops all flow. With power applied, the magnetic field is neutralized and shot is allowed to flow through the valve. If the power is interrupted for any reason, the permanent magnet in the valve securely holds the shot. The valve is factory calibrated and results are supplied upon request.

The MagnaValves provides reliable, repetitive, and consistent media flow rates for shot peening and blast cleaning applications. The MagnaValve makes it easy to document flow rates and establish or repeat a good set-up. The valve meets the requirements of SAE AMS 2430, AMS 2432 and other aerospace and commercial specifications.

Clear and comprehensive installation manuals simplify installation for the 120 Vac Series MagnaValves and the FC Controller. In addition, the products are supported by the Electronics Inc. application engineering staff.

Note: The power input signal to this family of MagnaValves is 50 Vdc using PWM, Pulse Width Modulation, provided by the FC Controller which operates from 120 Vac mains. Also see the 24Vdc MagnaValves for low voltage installations.
