Uniform ore drawing in mineral processing technology

What are the disadvantages of pinch valve?  

The valve is mainly used in low pressure environment, generally less than PN 16.

Rubber casing is the core of the pinch valve, so the using temperature has limitation, usually between -20~65 ℃.  

Limited by rubber process, the caliber of pipe valve usually is within DN 300 mm in order to meet the quality of casing strength. Large caliber pinch valves bring higher prices.
