ABSTRACT:
On/off solenoid ball valves of the invention comprise at least one inlet port; at least one pressure control outlet port; at least one exhaust port; at least one check valve positioned between the pressure control outlet port and the exhaust port; and at least one bypass orifice positioned to allow inlet fluid flow to the pressure control outlet port irrespective of whether the valve is in the “on” or “off” position. Because of their ability to provide unique and controlled flows, valves of the invention are able to be used in applications previously off limits to on/off solenoid ball valves.
