Pinch Valves

(8 products)

Pinch valves are a type of flow control valve that use a flexible tube or sleeve and a pinching mechanism to control the flow of fluids, slurries, powders, or granular materials. The valve operates by compressing the flexible sleeve with a mechanical pinch or pressure, effectively closing off the flow. When the pinch is released, the sleeve returns to its original shape, allowing fluid to flow through.

Advantages of Using Pinch Valves

  • Excellent for Handling Slurries and Solids

    Pinch valves are highly effective in handling abrasive slurries, solids, and viscous fluids. The flexible elastomer sleeve inside the valve allows for full, unrestricted flow, minimizing clogging and wear, making them ideal for industries such as mining, wastewater, and chemical processing.

  • Minimal Fluid Contact with Valve Components

    In pinch valves, the fluid only comes into contact with the flexible sleeve or tubing, not the valve body or other mechanical parts. This reduces the risk of contamination and corrosion, extending the lifespan of the valve and reducing maintenance needs.

  • No Dead Zones or Cavities

    Pinch valves have a streamlined design with no dead zones where materials can accumulate. This makes them ideal for sanitary applications, such as food processing and pharmaceuticals, where cleanliness and hygiene are essential.

  • Easy Maintenance and Replacement

    The simple design of pinch valves allows for quick and easy replacement of the internal sleeve or tube without needing to disassemble the entire valve. This reduces downtime and lowers maintenance costs.

  • Full Bore Flow

    When fully open, pinch valves allow for full bore, unobstructed flow, which results in minimal pressure drop and reduced energy consumption. This is beneficial for maintaining high flow rates and system efficiency.

  • Reduced Noise and Vibration

    Pinch valves operate with minimal noise and vibration because there are no metal-to-metal contact parts. This characteristic is particularly beneficial in environments where noise control is important or where reducing vibration is necessary to protect nearby equipment.
