ABSTRACT:
A diverter valve includes a valve body formed with a pair of openings. Inlet ends of a pair of discharge tubes are respectively carried by and extend through these openings. An elongated elastomeric strp then may be wound about each tube extended end to form a gasket. This wound strip is held in place by a clamp. The valve further includes a movable member formed with an opening to carry an outlet end of an intake tube. The movable member is pivotally attached to the valve body by two spaced apart pairs of link bars. As connected, the pairs of link bars are positioned in a parallel relationship. Operatively attached to one end of the movable member is a piston rod of an air cylinder which in turn is attached to the valve body. During use the movable member may be selectively positioned by the air cylinder to align the outlet end of the intake tube end with either discharge tube inlet end. Thus, a material flow may be diverted to either of two remote locations to which outlet ends of the respective discharge tubes are connected. During this flow the gasket forms an effective seal between the aligned tube ends to inhibit any loss of material or entrance of foreign matter exterior of the valve.
