TUBING PINCH VALVE DEVICE ABSTRACT OF THE DISCLOSURE A pinch valve is provided for controlling the flow in a flexible wall tube. The valve includes a slotted saddle with female threading to receive a male threaded stem which is actuated within the saddle by a knob integrally connected to the stem. The slotted saddle may be installed onto an existing tube run without requiring disconnection. The stem has a spherical tip which contacts the tube to collapse to decrease the area flow therethrough. The knob and saddle are closely fitted to prevent spreading of the saddle during high thread loads. Calibration is also provided so that a desired flow control can be repeated with accuracy.
