Abstract
A solenoid valve assembly capable of providing a continuous flow of pressurized inert gas to operate a process tool without interruption. A system comprising the solenoid valve assembly is also provided. The valve assembly comprises a manifold that is internally fluidly connected to each of the internal pressure ports, the internal actuator port, and the internal relief port of each solenoid valve, and wherein the manifold comprises a dedicated external relief port for each of the solenoid valves, wherein the dedicated external relief port is in fluid communication with the internal relief port of the respective solenoid valve such that, when one of the solenoid valves is de-energized, a second source of pressurized inert gas can be connected to the external relief port and supply pressure to the respective pneumatic valve operated by that solenoid valve. The system allows a controller to be capable of being removed away from the system such that a panel comprising the valve assembly remains on the fluid system.
