Dual’s Straight-Through Pinch Valve consists of a tough, but flexible full bore sleeve, which forms part of the pipeline.  The valve is closed mechanically via movement of a pinch gate located above the sleeve.  The core of the Dual Straight-Through Pinch Valve is the sleeve.  The valves are well suited for on/off and throttling control applications involving slurries, powders, liquids, granulated materials and applications where scale build is a problem.
