A control valve controls fluid to and from a motor or the like from a rotary shaft and it includes a pair of stationary valve members facing each other and having facing annular channels therein. The annular channel of one of said stationary valve members communicates with a motor passage leading to the motor. The annular channel of the other stationary valve member communicates with a source passage leading to the fluid source and with a vent passage leading to atmosphere. A pair of plugs secured in this latter annular channel provides an arcuate source channel and an arcuate vent channel. A rotatable valve disc driven by the rotary shaft and arranged between the stationary valve members has a port therethrough which alternately communicates the annular motor channel in said one stationary valve member with the arcuate source channel and the arcuate vent channel in the other stationary valve member for controlling the fluid to and from the motor or the like. The rotatable valve disc preferably includes a pair of discs and intermediate resiliently compressible means. The control valve also preferably includes a housing for receiving the stationary valve members and the rotatable valve disc.
