Pinch valves are a versatile valve type that has become a favorite for many industries. They are also considered to be safe and cost-effective. They can be used in a variety of processes, including slurries, liquids, granular materials, and corrosive media.
Pinch valves are designed to isolate the flow media from the environment. This is achieved by a rubber sleeve that forms a tight shutoff around the trapped particles. The sleeve is often made from natural or synthetic rubber. The elasticity of the material helps the valve to resist wear from corrosive media. The sleeve is usually reinforced with fibers to add strength.
There are three main parts of a pinch valve: the body, the sleeve, and the pinching mechanism. The sleeve is the most common component of the valve. The sleeve is only replaceable, which reduces maintenance costs. The pinching mechanism is usually a handwheel or push/pull pneumatic cylinder. These valves are commonly used in a variety of applications, including medical instruments and laboratory equipment. The pinching mechanism is a molded sleeve that comes in standard dimensions.
The valve’s body is typically made of aluminum or polyamide blends. The sleeve is usually a food grade rubber. It is also available in a variety of other qualities, such as rubber reinforcement. The sleeve is abrasion-resistant, and the liner is usually abrasion resistant, too.
A pinch valve is a reliable and economical solution for controlling abrasive flow. Unlike other types of valves, it has a 100% tight shut-off. It can be operated manually or by electric motor actuators. These actuators can be used to operate the valve either automatically or semi-automatically.
In general, pinch valves are used to control the flow of liquids, granular materials, and solids. This includes sewage treatment, industrial slurries, and clinical analyzers. They are primarily applied in applications where the evr valve media needs to be isolated. A pinch valve is not suitable for vacuum applications because of its full bore.
Flowrox offers flow control solutions to the heavy duty industrial industry. Whether you need a custom-designed valve, a reversible motor, or an extended hub, Flowrox has the industrial valve for you. Their valves are suitable for abrasive materials, and are particularly well suited for applications in the water and wastewater industries. They are also ideal for controlling corrosive materials, including sludges and acids.
A pinch valve can be installed on a variety of piping systems, from small to large, and can be operated manually or by electric motor. The sleeve is the only part of the valve that requires replacement. When choosing a pinch valve, you need to choose a sleeve that is abrasion resistant. The material should be able to withstand the temperatures and pressures that will be applied during the process. The valve should be able to perform effectively for its rated pressure class.
Typical specifications include the flange, pressure class, and valve type. There are also end flange configurations that connect flush with the transport tubing.
