ABSTRACT:
A control valve for a particulate material blender which permits either blending or bypassing with pressurized gas or discharging the material without pressurized gas, but prevents undesirable interconnections. A cylindrical body with four access ports spaced around the body has a rotor with connecting passages within the body. In one embodiment, the rotor interconnects either the gas entry port to the blender port alone, the gas entry port to the blender and bypass ports, or the blender port to the discharge port as it rotates into one of its three positions. A suitable rotation means, for example, two rotary actuators, are used to secure the three positions of the valve, while preventing any other rotational positions.
