A control valve of the angle pattern type has a valve body with first and second valve members supported by the valve body such that one of the members is adjustably movable relative to the other. The control valve has a fluid inlet, a fluid outlet, and a fluid passage from the inlet to the outlet for the flow of fluid therethrough. The valve body has a hollow portion in the fluid passage defining a cylindrical section, and the valve members define a control orifice therebetween within the passage for the flow of fluid therethrough, the flow of fluid being generally radially through the orifice. An inlet chamber is located in the passage at the entrance of the control orifice. The passage and control orifice direct the fluid flow such that the fluid turns 90°as it flows from the chamber into the control orifice and turns 90°as it flows from the control orifice. The cross section of the chamber taken perpendicular to the longitudinal axis of the cylindrical section of the valve body is generally an eccentric annulus. One of the valve members is adjustable axially relative to the other to vary the size of the control orifice.
