Buy a 1-1/2"(DN40) pinch valve from a reliable pinch valve manufacturer. The aluminum manual pinch valve is especially suited for handling abrasive or viscous fluids because the rubber sleeves can be changed easily and quickly.
Pinch valves are commonly used in industrial applications where precise flow control is not required, and the fluid being handled is abrasive or corrosive. They can be used in chemical processing to control the flow of chemicals through pipelines and tanks, and in mining and minerals processing to control the flow of slurries, tailings, and other abrasive fluids.
