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.

Pinch valves are innovative flow control devices that use a flexible tube or sleeve to regulate fluid flow. When the valve is actuated, a mechanism compresses or "pinches" the sleeve, restricting or completely stopping the flow. These valves are particularly suited for handling slurries, abrasive materials, viscous fluids, or fluids with suspended solids, making them a popular choice in industries such as mining, wastewater treatment, chemical processing, and food and beverage. Their unique design ensures reliable performance and minimal maintenance in demanding environments.

One of the key advantages of pinch valves is their full-bore design, which eliminates any obstructions in the flow path when the valve is open. This design minimizes pressure drop and turbulence, making them highly efficient for systems requiring smooth fluid flow. The flexible sleeve is typically made from durable materials like natural rubber, silicone, or EPDM, chosen based on the fluid’s chemical compatibility and operating conditions. The absence of complex internal parts, such as seats or seals, reduces wear and tear, ensuring long-lasting performance even with abrasive or corrosive fluids.

Pinch valves are available in manual, pneumatic, or electric actuation options, providing flexibility to meet different operational needs. Manual valves are ideal for simple, low-cost setups, while pneumatic and electric options allow for remote control and automation in complex systems. Easy to install and maintain, pinch valves are a cost-effective solution for applications requiring robust and reliable flow control. By offering excellent durability, versatility, and ease of operation, pinch valves are a trusted choice for professionals managing challenging fluid handling systems.

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.
