Non-wetted pinch valves
The most common uses of non-wetted pinch valves are in wastewater treatment plants, power plants, and mining. These valves can handle a wide range of fluids, including chemicals, corrosive media, powders, and other particles. They are also used in the food, glass, and electronics industries.
The most common type of non-wetted pinch valve is spring-loaded. This valve works by using pressure to pinch an internal sleeve to shut off flow. These valves are available in IP67 and IP68 enclosures. While spring-loaded pinch valves are often the simplest to use, they’re not suited for all applications.
Diaphragm valves
Diaphragm pinch valves are designed to limit the flow of a fluid. They feature a polymeric diaphragm that moves to touch the bottom of the valve body and restrict the flow of fluid. These valves can be opened fully or partially, depending on the fluid that needs to be controlled. These valves also have a limited operating pressure and temperature, so they must be replaced periodically.
Diaphragm valves are typically available in 1/4 to 1/2-inch sizes and operate up to 150 psi. Their features and designs vary, and you can also find ones that are autoclavable. Some models also come with visual position indicators to ensure proper valve operation.
Linear motion pinch valves
Linear motion pinch valves are a simple device that https://evrproducts.com/products/pinch-valves/ control the flow of fluids and gases through a pipe. These valves have few components and are used in a variety of applications. They feature a low pressure drop, an effective throttling range, and are suitable for liquid, solid, and slurry applications. They also feature smooth walls and a resilient liner. The throttling range of pinch valves is generally a little over 50%.
Linear motion pinch valves are most commonly used in pneumatic and aseptic production lines, where the purity of the product is vital. They are not recommended for high-pressure flows or for liquids that have high temperatures. They are best suited for slurries and liquids with high suspended solids, as well as for pneumatic conveying of solids. In addition, the operating mechanism of a pinch valve is isolated from the fluid, which makes it ideal for applications where corrosion is a problem.
Solenoid-operated pinch valves
Solenoid-operated pinch valve (SOV) is a device for controlling the flow of gas and liquid through a piping system. It is controlled by an electric or hydraulic motor and actuates a valve in either a closed or an open position. This device can be a single-port, dual-port, or three-port design, depending on the needs of the application. The valves can be manual, semi-automatic, or fully automatic, depending on the power source.
A common use for a pinch valve is in dialysis machines. These machines frequently replace tubing used to carry blood. During these changes, the valve is a simple way to close the tubing and prevent the fluid from spilling out. It is also easy to replace the tubing if it needs to be replaced.
