A [pinch valve](http://www.corrosion-resistant-valves.com/Pinch-valve.html) is a full bore or fully ported type of control valve which presents no obstruction to flow passage. There are a few types of pinch valves based upon application…Pinch valves used for fluids usually employ a device that directly contacts process tubing. Forcing the tubing togethor will create a seal that is equivalent to the tubing’s permeability.
