摘要:
A pump set for use with a pumping apparatus includes tubing for carrying a liquid. A valve mechanism is mounted to the tubing between an inlet section and a pump engagement section. The valve mechanism includes a first port connected to the inlet section of the tubing, a second port connected to the pump engagement section of the tubing, and a valve disposed between the first and second ports. The valve includes a stem rotatably mounted within a stem holder. The stem includes a flow passage extending through the stem and having an open V shape whereby a narrow open end of the flow passage communicates with the first port and a wide open end of the flow passage communicates with the second port to place the inlet section of the tubing in communication with the pump engagement section of the tubing.
