A pinch valve is a full bore, fully ported control valve

A pinch valve is a full bore, fully ported control valve that uses a pinching effect to prevent fluid flow. They can be operated manually or with a solenoid, and are used in a variety of applications. Here are some common types. To learn more, check out our articles on pinch valves, rubber sleeve valves, and solenoid valves.

Full bore

A full bore pinch valve is a versatile valve used to control the flow of bulk materials. Pinch valves function like a shut-off valve by preventing product flow. Air pressure on the valve sleeve actuates the flexible sleeve, which closes the valve. The result is a pressure drop that allows bulk material to pass through the full bore. These valves are often used in proportional control applications, and are a great choice for industries like iron and steel, aluminium, and cement.

Full bore pinch valves block or admit full passage of dry bulk materials. The flexible sleeve is compressed by pneumatic cylinders, providing long-lasting service. This type of valve grants 100% hermetic sealing for product flow when closed, and is also leak-tight.

Fully ported

A Fully ported pinch valve is a full bore control valve that utilizes a pinching effect to restrict flow. This valve is useful in regulating the flow of corrosive and abrasive materials. These valves can be operated manually or electromechanically. The manual process involves lowering a gate into a sleeve, while the electromechanical process uses fluid actuation and air pressure.

These valves are designed for high-performance applications in tough sludge or slurry applications. A fully ported design eliminates dead spots, and a high-strength fabric reinforced rubber sleeve provides excellent flow control. Depending on the application, these valves are available with a throttling capability, making them ideal for regulating the flow of abrasive media.


A solenoid-operated pinch valve is a type of pressure valve. The solenoid has a coil that is connected to a spring. The spring is movable. ThisĀ https://evrproducts.com/products/pinch-valves/ spring acts to compress the armature shaft, preventing the fluid from flowing through the valve.

A solenoid-operated pinch valve has two basic configurations: spring-closed and actuated-open. In a spring-closed configuration, a coil spring pushes the plunger towards the wall 12 and closes the tubing. A solenoid-operated pinch valve has a coil that is movable in a magnetic field. When the solenoid is powered, the plunger moves toward the right, allowing the valve to open.


The pinch valve is a type of valve that seals fluids. Its non-contact function makes it suitable for a wide range of applications, including sewage treatment, food processing, and medical manufacturing. Its flexibility and efficiency make it a popular choice for many industries. In addition to being used for closed-loop control, pinch valves are also useful for non-contact applications, such as spraying.

A pinch valve works by utilizing pressure differentials to open and close. The pressure differentials must be precise in order to work properly. In addition, the material used for the sleeve should have the right resistance to abrasion and temperature.
