Abstract
A force and multiplication control valve which utilizes ball leverage to produce multiplied forces on a ball lock seat device. Constantly changing wear surfaces provide self-cleaning and self-compensating wear characteristics to provide extremely high reliability of the device of the present invention. Non-hardened metals can be used because of the self-compensating wear characteristics. High pressures can be handled by the valve of the present invention because of the ability to use metals for metal contact surfaces to produce a valve seal. Additionally, the present invention can be used with many fluids which would normally be corrosive to materials used in valves employing rubber-type seals. The device can be configured to act as a pressure regulator control valve, a solenoid valve and can be used with various fluids including gases and liquids.
