14 best pinch valves
Pinch valves are industrial valves used in a variety of applications to control the flow of fluids and gases through flexible tubing. These valves are designed to regulate flow by pinching or compressing a flexible tube or sleeve to control the passage of the fluid. Here's what you should know about pinch valves:
Operating Principle: Pinch valves operate on a simple principle. A flexible tube or sleeve is placed between the valve body and a pinching mechanism, which can be manual or automated. When the pinching mechanism is engaged, it compresses the tube or sleeve, effectively closing off the flow of the fluid.
Flow Control: Pinch valves provide precise flow control by varying the degree of tube compression. Partially closing the valve allows for throttling the flow, while fully closing it stops the flow completely.
Versatility: Pinch valves are versatile and can handle a wide range of fluids, including corrosive chemicals, abrasive slurries, powders, and even gases. This versatility makes them suitable for various industries, such as chemical processing, mining, wastewater treatment, and pharmaceuticals.
Materials: The choice of materials for the tube or sleeve is critical, as it determines the valve's compatibility with the fluid being controlled. Common materials include natural rubber, synthetic elastomers, and various thermoplastics.
Manual and Automated Options: Pinch valves can be operated manually by using a lever or handle to pinch the tube or sleeve. They can also be automated using pneumatic or electric actuators for remote control and integration into automated systems.
Low Maintenance: Pinch valves are known for their low maintenance requirements since the valve body doesn't come into contact with the fluid. This reduces the risk of corrosion and contamination, contributing to a longer service life.
Cost-Effective: In many cases, pinch valves are considered cost-effective solutions for flow control due to their simplicity and durability.
Applications: Pinch valves find application in a wide range of industries, including chemical processing, mining, food and beverage, pharmaceuticals, wastewater treatment, and more. They are particularly useful in situations where maintaining purity and preventing contamination are crucial.
Installation: Installing pinch valves is relatively straightforward, as they can be easily integrated into existing piping systems using standard tube fittings or flanges.
Maintenance: Regular inspection and replacement of the tube or sleeve may be necessary to ensure the valve's continued performance over time, especially in applications with abrasive or corrosive fluids.
Pinch valves are a reliable choice for controlling the flow of various fluids in industrial settings, offering flexibility, durability, and ease of maintenance. Their suitability for handling corrosive and abrasive materials makes them valuable assets in many industrial processes.

User questions & answers
| Question: | Do you have to use the earth wire |
| Answer: | I used it for my husband's feeding tube and it worked. The main thing is you have to be able to fit it over the end of it. Once you clear the end, it slides where you want it. I don't remember what size his tube was. It was pulled 4 months ago. I purchased the middle size. |

User questions & answers
| Question: | Is this clamp made of plastic or metal |
| Answer: | You can but for the best crimp I would recommend the crimping tool |
| Question: | Will this fit od 3/8" id 1/4" tubing similar to what is used for camelbak/platypus tubing |
| Answer: | Sure they will, the assortment would cover you, otherwise if you just want a few, make sure you order the right size. Get the outside diameter of your garden hose (convert your finding to metric if need be) and choose the corresponding clamp size and *BAM* Foleno's your Uncle! |
| Question: | Will this fit od 3/8" id 1/4" tubing similar to what is used for camelbak/platypus tubing |
| Answer: | I've MaGyvered it using a similar crimper but if your going to use these and a clean look is what your after, you should use a tool that's specifically made to crimp these clamps. $18 for the array of sizes to inc the tool is pretty good. Especially since the clamps are stainless steel. |
| Question: | what are the dimensions of the openings of this tube please |
| Answer: | You can remove the clips by unseating the end with the tab running through it. Small screwdriver will flip it loose. If you want to reuse then reattach the clip at this point, then expand the cinched section a little with a couple of needle nose pliers. Maybe once or twice reuse at best. I've loosened to reposition the clamp many times. |
