Summary:A combined torque motor and rotary flow control valve unit (10) incorporating a torque motor (12) and a rotary flow control valve (14). The unit (10) includes an enclosure member (70) surrounding a rotor (38) of the torque motor (12) and fluid-tightly isolating the stationary part (18) of the torque motor from a sealed chamber (96) defined within the enclosure member (70) to prevent fluid leakage. Preferably, the chamber (96) in the enclosure member (70) is communicated with a fluid inlet (56) of the valve (14) to counterbalance fluid pressures acting on a rotary flow control member (54) of the valve, thereby eliminating any axial thrust that would otherwise be exerted on the rotary flow control member due to the fluid pressure acting thereon in one direction.
