ABSTRACT:
Flow control valves (10) and (80) each include a cylindrical body (11) or (82) that is open through a number of ports (13), (14) and (15), the ports to be opened and closed by a resilient ball (16) that is selectively moved into and out of alignment with each port by lowering and turning a valve basket (15) and (60). The valve basket has co-planer essentially parallel arms that extend from ends of a web wherebetween the resilient ball is caged, which valve basket is secured to the end of a valve basket stem (19) or (89). The valve gasket is displaced vertically and turned by an actuator (48) or (94), through a handle (49) or (109), the turning of which handle operates through a system of opposing upper and lower cams (40) and (23) or a clutch cam system (81) to both vertically displace and turn the valve basket system stem and valve basket.
