Abstract
A valve installation is provided, including a valve assembly having a valve, and a fluidized valve actuator coupled with the valve assembly. The actuator includes at least two cylinders and pistons positioned to communicate fluid to apply pressure to the valve assembly. Extension of each piston communicates pressure to the valve assembly and at least partially lifts the valve into an at least partially lifted and open position. The valve installation may be used to regulate fluid flow in various systems, including cyclical swing adsorption processes.
