A knife gate valve is a type of valve that is specifically designed for use in applications where there is a need to control the flow of viscous or abrasive media. It is commonly used in industries such as mining, pulp and paper, wastewater treatment, and chemical processing. The knife gate valve is known for its ability to provide a tight shut-off and handle high pressures and harsh environments. This product overview will provide a comprehensive understanding of the Knife Gate Valve and its key attributes.
The Knife Gate Valve comes in two different pressure ratings, Class 150 and Class 300. The pressure rating refers to the maximum pressure that the valve can withstand. Class 150 can handle pressure up to 285 psi, while Class 300 can handle pressure up to 740 psi. This makes the Knife Gate Valve suitable for a wide range of industrial applications where high pressure is a requirement.
The Knife Gate Valve is available in three different end connections: wafer, lug, and flanged. The wafer type is the most commonly used and is designed for installation between two flanges. The lug type has threaded inserts on the valve's body that allow it to be installed without using flanges. The flanged type has extended flanges on both sides, providing a secure and leak-free connection. The end connection type depends on the specific requirements of the application.
The Knife Gate Valve is a type of gate valve, which is a linear motion valve used to control the flow of media through a pipe or duct. It is called a knife gate valve because of its sharp-edged gate that cuts through the media to control the flow. This valve type is ideal for controlling slurry, liquids with suspended solids, and other viscous media. It is also commonly used in applications where bi-directional flow control is required.
The Knife Gate Valve is available in a range of sizes from 2 inches to 48 inches. This size range makes it suitable for use in various pipeline systems, from small to large-scale industrial applications. The size of the valve required depends on the size of the pipeline and the flow rate of the media.
The Knife Gate Valve is available in different body materials, including cast iron, ductile iron, carbon steel, and stainless steel. The choice of body material depends on the specific application's requirements, such as the type of media flowing through the valve, the pressure and temperature conditions, and the corrosiveness of the media. The use of stainless steel makes the valve suitable for handling corrosive media, while cast iron is more suitable for non-corrosive applications.
The Knife Gate Valve is also available in an SS (stainless steel) gate valve version. This type of valve is ideal for applications that require corrosion resistance, high pressure handling, and bi-directional flow control. The SS gate valve is also suitable for use in applications that require frequent cleaning or sterilization, such as in the food and beverage industry.
The Knife Gate Valve is also available in a pneumatic version, which means it can be operated using compressed air. This type of valve is suitable for applications that require remote or automatic operation, as it can be controlled using a pneumatic actuator. The pneumatic knife gate valve is ideal for use in hazardous environments or where manual operation is not feasible.
The Slurry Knife Gate Valve is a specialized version of the Knife Gate Valve that is designed for handling slurry or liquids with suspended solids. It is equipped with a thicker gate and seat material to withstand the abrasive nature of the media and prevent clogging. The Slurry Knife Gate Valve is commonly used in industries such as mining, wastewater treatment, and chemical processing.
The Bi-Directional Knife Gate Valve is designed to provide tight shut-off in both directions. This means that the valve can control the flow of media in either direction, making it suitable for applications that require flow reversal. The bi-directional feature also prevents backflow, ensuring the safety and efficiency of the pipeline system.
