Abstract
A pinch valve includes a base having a body and a head and an anvil aligned therewith and including a shaft and a pinch tip. The head is disposed at a first end of the body. The head includes a contact protrusion that has a radiused surface defining an apex disposed at a point furthest from a second end of the body and centered around a base axis. The pinch tip is disposed at a first end of the shaft and includes two planar surfaces disposed at acute angles relative to an anvil axis to form an acute point disposed at a point furthest from a second end of the shaft and centered around the anvil axis. The base and anvil are aligned to form a gap between the radiused surface and the acute point and are movable between a first and second positions to change dimensions of the gap.
