Abstract
A control valve (100) comprises a conduit (102), a controller (104), a sensor unit (106; 146, 148), a cylindrical housing (112) and one or more regulating columns (124, 126). The conduit further comprises a hollow cylindrical body (114) and two smaller and shorter cylindrical extensions (116, 118) for the insertion of the regulating columns which are orthogonal to the hollow cylindrical body and provide a contactless means to control the flow of the medium (101) in the conduit.

A control valve for regulating shot peening, the control valve comprising:
- a conduit for transferring a ferrous shot medium;
- a magnet aligned with the conduit for applying a magnetic field to the ferrous shot medium;
- and
- an oscillator connected to the magnet for causing the magnetic field to oscillate from 8 Hz to 30 Hz,
- wherein the magnet comprises a first magnet and a second magnet, the first magnet and the second magnet being at an angle so as to not be parallel with respect to each other for regulating transference of the ferrous shot medium by the magnetic field, and
- wherein the oscillator is configured to change polarity of the magnetic field.
A method for regulating a ferrous shot medium, the method comprising:
- providing ferrous shot medium;
- presenting a first magnet and a second magnet that are at an angle so as to not be parallel with respect to each other for generating a magnetic field to the ferrous shot medium in order to regulate transference of the ferrous shot medium;
- oscillating the magnet for causing the magnetic field to oscillate from 8 Hz to 30 Hz and for changing polarity of the magnetic field;
- and
- circulating used shot medium in a shot peening machine.
A control valve for regulating shot peening, the control valve comprising:
- a conduit for transferring a ferrous shot medium;
- a magnet aligned with the conduit for applying a magnetic field to the ferrous shot medium;
- an oscillator connected to the magnet for causing the magnetic field to oscillate from 8 Hz to 30 Hz;
- and
- a housing for enclosing the magnet in order to prevent infiltration of foreign particles or moisture,
- wherein the housing comprises at least one detachable cover for allowing access to internal components of the control valve, and
- wherein the oscillator is configured to change polarity of the magnetic field.
