A surgical system comprising: a surgical implement comprising a first port and a second port; a fluid pressure supplying device configured to supply a pressurized fluid to the surgical implement; a fluid exhaust manifold configured to direct a fluid exhaust from the surgical implement; a pneumatic valve (300, 710) configured to rotate from a first position in which the pneumatic valve places the first port of the surgical implement in fluid communication with the fluid pressure supplying device and places the second port of the surgical implement in fluid communication with the fluid exhaust manifold, to a second position in which the pneumatic valve places the first port of the surgical implement in fluid communication with the fluid exhaust manifold and the second port of the surgical implement in fluid communication with the fluid pressure supplying device, and the pneumatic valve is configured to rotate within the housing from the second position back to the first position, in one rotational direction; wherein the pneumatic valve comprises: an axially symmetric valve body; and a housing configured to accommodate the axially symmetric valve body, wherein the axially symmetric valve body is configured to rotate within the housing from the first position to the second position and back to the first position in the one rotational direction; wherein the axially symmetric valve body (302, 304) further comprises flow grooves (522, 523, 524, 525, 526, 527, 528, 529) formed on a circumferential surface of the axially symmetric valve body and extending from openings (342, 352, 344, 358, 348, 354, 356, 346) of one or more connection channels (332, 334, 336, 338), wherein the flow grooves define opening or closing timing sequences of the one or more connection channels; wherein the surgical implement is a dual actuation vitreous probe and wherein a rotational speed of the pneumatic valve corresponds to a cutting rate of the dual actuation vitreous probe; wherein the surgical system further comprises a drive shaft configured to engage the axially symmetric valve body and to rotate the axially symmetric valve body in the one rotational direction in the housing; wherein the axially symmetric valve body comprises a drive shaft engagement interface configured to engage and receive a rotational driving force from the drive shaft, and wherein the drive shaft engagement interface provides radial and tilt compliance between the drive shaft and the valve body. a surgical implement comprising a first port and a second port;
