A pinch valve (10) for pinching closed a tube (18) is comprised of a linear actuator (12) connected pivotally a pointer (16). The linear actuator is parallel to the tube and the end of the pointer that engages the tube is made to follow a path that is perpendicular to the tube when the valve is closed. When pinch valve is closed, the pointer is perpendicular to, and supported by, both the linear actuator and the tube. |
