Dual Straight Through Diaphragm Valve (DSTDV)
Dual Straight Through Diaphragm Valve (DSTDV)
Dual’s Straight-Through Diaphragm Valve consists of the valve body and a diaphragm. The valve is closed mechanically via movement of a compressor gate which is located above the diaphragm. The valves are well suited for on/off throttling control applications involving slurries, powders, liquids, granulated materials and applications where scale build is a problem.
