Abstract

A valve assembly for controlling fluid flow is provided. The valve assembly includes a housing having a first chamber and a second chamber, an actuator assembly configured to move between a first position and a second position within the first and second chambers, a plurality of fluid ports in fluid communication with the first chamber, and a plurality of fluid ports in fluid communication with the second chamber. The first position of the actuator assembly defines a first series of fluid flowpaths through the plurality of fluid ports of the first and second chambers. The second position of the actuator assembly defines a second series of fluid flowpaths through the plurality of fluid ports of the first and second chambers.
