According to one aspect, a rotary exhaust valve system includes an arcuate ring having a first plurality of apertures and a rotary valve ring disposed in an overlapping relation with the arcuate ring. The rotary valve ring has a second plurality of apertures forming therein corresponding to at least some of the first plurality of apertures. A first crank is disposed in a first side of the rotary exhaust valve system, and a second crank is disposed in a second side of the rotary exhaust valve system. The second crank is connected to the first crank and the rotary valve ring, and the first crank actuates the second crank and moves the rotary valve ring such that openings of the first plurality of apertures are closed and opened.

The fluid extraction system of claim 8, wherein the actuation unit further comprises a spacer disposed on the actuator to change a length of the actuator and thereby adjust a range of motion of the first crank and the second crank such that openings formed by the at least some of the aligned first and second plurality of apertures are adjustable. 10. The fluid extraction system of claim 9, wherein the first member is stationary with respect to the second member. 11. The fluid extraction system of claim 7, further comprising: a first seal disposed between the first member and the second member; anda second seal disposed between the first member and the second member opposite the first seal, wherein the first plurality of apertures and the second plurality of apertures are disposed between the first seal and the second seal. 12. A rotary exhaust valve system for testing operation of a compressor, the rotary exhaust valve system comprising: an O-ring having a first aperture formed therein;a rotary valve ring disposed in an overlapping relation with the O-ring, the rotary valve ring having a second aperture formed therein; andan actuator unit having an actuator arm, a first crank, a second crank, and a spacer disposed between and connecting the actuator arm and the first crank;wherein the first crank is connected to the second crank via a crank shaft passed through a separation member separating a first side from a second side of the rotary exhaust valve system;wherein the second crank is further connected to the rotary valve ring to adjust alignment of the second aperture with respect to the first aperture, whereby an opening between the first and second aperture is adjusted based on size of the spacer. 13. The rotary exhaust valve system of claim 12, wherein the spacer is adjustable. 14. The rotary exhaust valve system of claim 12, wherein the spacer is interchangeable with another spacer of a different size. 15. The rotary exhaust valve system of claim 14, further comprising: a first seal disposed between the O-ring and the rotary valve ring; anda second seal disposed between the O-ring and the rotary valve ring opposite the first seal, wherein the first aperture and the second aperture are disposed between the first seal and the second seal. 16. The rotary exhaust valve system of claim 14, wherein a flow of exhaust fluid from the compressor through the opening is modulated as the opening is adjusted. 17. The rotary exhaust valve system of claim 16, wherein an axial flow of the exhaust fluid is transformed to a radial flow through the first aperture and the second aperture. 18. The rotary exhaust valve system of claim 12, wherein the opening includes an area of an exposed void formed by the alignment of the second aperture and the first aperture.
