    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 maintain a pinch valve?

    • Regular inspection: Regularly inspect the valve for any signs of damage or wear, such as cracks, cuts, or tears in the sleeve.
    • Lubrication: If the valve has a manual actuator, apply a small amount of lubricant to the actuator shaft and any other moving parts to keep the valve operating smoothly.
      Cleaning: Depending on the application, the valve may need to be cleaned periodically to remove any build-up of debris or sediment. Cleaning can be done by flushing the valve with water or a suitable cleaning solution.
    • Sleeve replacement: The flexible sleeve in a pinch valve is a worn component and will eventually need to be replaced. Replacement intervals will vary depending on the application, but it is generally recommended to replace the sleeve every 6-12 months.
    • Actuator maintenance: If the valve has an automated actuator, follow the manufacturer's recommended maintenance procedures for the actuator, such as checking for proper alignment and torque.
    • Follow manufacturer recommendations: Always follow the manufacturer's recommendations for maintenance and repair. Pinch valve designs can vary between manufacturers, so it is important to use the recommended procedures and parts.
