Abstract
A rotary valve adapted for use in utility scale fluidic systems improves over conventional valving schemes by affording reductions in weight, pressure drop, cost, and actuation time, as well as providing improvements in decompression performance, higher pressure capability, and longer operational life. One embodiment of a three way valve assembly utilizes electric actuation to adjust decompression in real time and facilitate port shaping. The valve assembly utilizes a pressure balanced rotor and seals to reduce actuation and bearing loads, as well as increase seal life.
