ABSTRACT:
A flow control valve for magnetic abrasive is disclosed. The valve employs a plurality of permanent magnets spaced around its circumference to set up a magnetic flux pattern. A valve disc of magnetic material mounted to a shaft for rotation is provided for controlling flow through the valve. When in the closed position, the disc completes the flux pattern set up by the magnets, preventing flow of magnetic abrasive through the valve without the need for effecting a complete mechanical seal.
