What Is A Pinch Valve?

A pinch valve is a type of fluid control valve. It applies a pinching force to the outer surface of flexible tubing. While pinching it collapses and seals the tubing to control fluid flow or pressure. The main body of a pinch valve is not in direct contact with the gas or the liquid, and only the inside of the tube will have direct contact with the liquid and gas fluid flowing through. Therefore, the pinch valve is not in direct contact with the fluid. Please refer to our youtube video: https://www.youtube.com/watch?v=5z31SR9wqgk

Why Use Pinch Valves?

Industry leaders looking for a low-maintenance and more cost-effective solutions for controlling liquids, gases, slurries and powders (incl. corrosive media) in a pipeline are turning to pinch valves over traditional valves (diaphragm valves, ball valves, butterfly valves, needle valves, etc.) Unlike traditional valves, pinch valves feature a straight-through flow, very little pressure drop over the valve, and full shut-off of media in the tube, making it the most practical and efficient solution for various ON/OFF flow control applications.

Why Use Proportional Pinch Valves?

See below for pressure curves representing 2-way (ON/OFF) control versus proportional control. If you need the option to vary or hold flow or pressure in your system a proportional valve allows you flexibility to adjust the valve opening from full open to closed or anywhere in between.

Advantages of Pinch Valves

Compact, lightweight design Easy cleaning (just throw away the tubing) Simple operation Eliminates media contamination Linear flow Quick tubing change-out High performance and reliability Easy valve exchange Maximize productivity Reduced valve costs Valve body not affected by corrosive fluids Requires very low maintenance

As technologies evolve, we see more and more applications that require increasingly demanding performances that are just not achievable with conventional pneumatic or solenoid pinch valves; there is a demand for proportional controls in order to regulate and monitor processes with greater accuracy, speed, and delivery. Regulation of the fluid or media is necessary and can be limited to several factors, including flow, net volume, temperature, positive or negative pressure, and viscosity. Filtration and dispensing applications benefit immensely from proportional pinch valves. Filtration is a method used to separate particles from a fluid. Filters require precise regulation of flow, along with monitoring positive and negative pressure at the membrane as the process occurs. Material build-up as the filter does its job means that increased flow or pressure may be needed in order to maximize the filters usefullness to a maximum point.
