Pinch valves are a type of valve that uses an elastic tube or sleeve to control the flow of fluid through a piping system or pipeline. The valve consists of a housing or body and a rubber or elastomer sleeve that is pinched or compressed by a mechanism within the body to control the flow of fluid.
This type of valve is commonly used in applications where precise control is required, or where the fluid being transported is abrasive or viscous.Pinch valves come in different sizes and pressure ranges to suit different applications.
They are typically available in sizes ranging from 1/2 inch to 36 inches, and pressure ranges from 5 PSI to 150 PSI. Some manufacturers offer higher pressure pinch valves for specific applications, such as mining or heavy-duty industrial applications.The material used for pinch valves is critical to their performance and durability.
Most pinch valves use an elastomeric sleeve made of materials such as natural rubber, neoprene, EPDM, or silicone. The choice of material depends on the properties of the fluid being transported and the operating conditions of the valve. In addition to the sleeve material, the housing of the pinch valve can be made of materials such as cast iron, stainless steel, or plastic.
Pinch valves have a wide range of applications in various industries. They are commonly used in chemical processing, mining, wastewater treatment, and food processing. Pinch valves are ideal for applications where the fluid being transported is abrasive, corrosive or contains particulate matter. For example, pinch valves are used to control the flow of slurries and pastes in the mining industry. In the food and beverage industry, pinch valves are used to control the flow of liquids and viscous fluids such as fruit pulp and sauces.In summary, pinch valves are a versatile and reliable valve technology that is well suited for various applications where precision control and durability are required. They are available in a range of sizes, pressure ranges, and materials and can be customized to suit specific applications.
