description	A two-stage servo valve comprising a first drive stage and a second fluid transfer stage. The fluid transfer stage includes a housing having a plurality of ports and a spool axially moveable within an axial cavity defined within the housing to control flow of fluid between the plurality of ports according to the axial position of the spool, wherein the drive stage is configured to cause axial movement of the spool. The housing has three ports, a first port being a supply port fluidly connected to a second port, being a control port, via a supply channel (sc) and a first control channel (cc1) via the spool cavity, and a third port being a return port fluidly connected to the control port via a return channel (rc) and a second control channel (cc2) via the spool cavity.
