DIAPHRAGM AND PINCH VALVES
With minimal wear, Diaphragm and Pinch Valves are suitable for corrosive and abrasive fluids
Diaphragm valves are characterized by a straight passage design, and are typically used with corrosive or abrasive fluids. This valve type may be either coated or feature a liner inside the body. Combined with the diaphragm, they are capable of performing their intended function with minimal wear.
Pinch valves are typically used in applications where the media need to be completely isolated from internal valve parts. The sleeve holds the flow medium, and subsequently isolates it from the environment, thus significantly reducing contamination. Pinch valves are found in abrasive and corrosive applications, slurries or processes with entrained solids. The latter is due to the fact that the flexible rubber sleeve is capable of closing drop-tight around the solids.
