Abstract
A shut-off valve incorporating a tube-cutting member, and including a tubing support channel extending through the valve body. An actuator closes off, and then severs, a tubing section which is extended through the channel in the valve during an actuation stroke of the valve, the actuator including first and second spaced-apart, generally parallel slots provided in the valve body and intersecting the tubing support channel, and a driving member and first and second actuating members, each actuating member disposed in a respective slot of the valve body. During a mid-portion of the actuation stroke, the first actuating member first engages, and then closes, the tubing disposed across the first slot. At the end of the actuation stroke, after the tubing has been closed, the second actuating member severs the tubing disposed across the second slot.
