pinch valve Particulates
Major components of a pinch valve consists of body and a sleeve. The sleeve will contain the flow media and isolate it from the environment hence reducing contamination to the environment. Generally used for slurries or processes with entrained solids, because the flexible sleeve allows the valve to close droptight around solids—solids that would typically be trapped by the seat or stuck in crevices in globe, diaphragm, butterfly, gate, or ball valves. The sleeve material can be selected upon the corrosiveness and abrasiveness of the flow media, a suitable synthetic polymer can be chosen. A pinch valve http://www.corrosion-resistant-valve...nch-valve.html may be the best type of valve for flow control application if the operation temperature is within the limit of the polymer.

What are pinch valve
A pinch valve 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.
