    Patent number: 9598986
    Abstract: A fluid flow control valve (10) having an elongated valve body (14) with a longitudinally extending aperture (14a) and a plurality of longitudinally spaced, radially extending ports (14b) formed therein. The valve body (14) includes an undercut portion (14c) located between two adjacent radially extending ports (14b). A valve spool (12) within the longitudinally extending aperture (14a) of the valve body (14) can be moved between first and second end limits of travel. The valve spool (12) has a plurality of lands (12a) and reduced diameter portions (12b) defining fluid passages (18) for fluid communication with selective radially extending ports (14b) of the valve body (14) depending on a longitudinal position of the valve spool (12) within the valve body (14).
