    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. 

    Pinch valve applications

    Tips: How to select the right size of pinch valve for a given application?

    • Determine the required flow rate: The first step in selecting a pinch valve is to determine the required flow rate. This can be done by calculating the volume of fluid or gas that needs to pass through the valve per unit of time.
    • Determine the size of the pipeline: Once the required flow rate is determined, the size of the pipeline or tubing that the valve will be installed in should be measured. This will help to determine the appropriate size of the valve.
    • Consider the pressure and temperature: The pressure and temperature of the fluid being handled are important factors in determining the appropriate size of the valve. Pinch valves are typically rated for maximum pressure and temperature, so it is important to select a valve that can handle the conditions in the application.
    • Consider the viscosity and density of the fluid: The viscosity and density of the fluid being handled can also affect the performance of the pinch valve. Thicker fluids may require a larger valve to maintain the desired flow rate.
    • Consult with the manufacturer: Pinch valve manufacturers can provide guidance on selecting the appropriate size of valve for a given application. They can take into account the specific requirements of the application and recommend the most suitable valve size.
