Flange End Gate Valve FLOVIN

A flange end gate valve is a type of industrial valve used to control the flow of fluid (liquids or gases) through a pipeline. It belongs to the family of multiturn valves and is commonly utilized in various industries, including oil and gas, petrochemical, water treatment, and more.

Here is a description of a flange end gate valve:

• Design: The valve is designed with a rectangular or circular gate or wedge-shaped element that moves perpendicular to the direction of the flow. The gate is positioned between two seats within the valve body. When the valve is fully open, the gate is lifted completely out of the fluid path, allowing for unobstructed flow. When the valve is fully closed, the gate comes down to create a tight seal against the seats, stopping the flow of fluid.
• Flange ends: The gate valve has flanged ends, which means it has protruding rims (flanges) that can be bolted to the corresponding flanges on the pipeline. This flanged connection provides a secure and leak-proof joint.
• Operation: Gate valves are operated by turning a threaded stem connected to the gate. When the stem is rotated, the gate moves up or down along the stem to open or close the valve. The operation is typically accomplished by using a handwheel, gearbox, electric actuator, or other types of actuators, depending on the valve size and application.
• Flow control: Gate valves are primarily designed for full-open or full-close operation, providing minimal resistance to the flow when fully open. They are not suitable for precise flow control since the gate is either fully blocking the flow or entirely out of the way.
• Pressure rating: Flange end gate valves come in various pressure ratings, and the specific rating should be chosen based on the application requirements and the pipeline’s operating pressure.
• Material construction: Gate valves are available in a variety of materials, including cast iron, carbon steel, stainless steel, bronze, and other alloys. The choice of material depends on factors such as the type of fluid being handled, temperature, pressure, and the corrosiveness of the medium.
• Maintenance: Proper maintenance is essential to ensure the reliable and efficient operation of gate valves. Regular inspections, lubrication, and replacement of worn-out parts are crucial to prevent leaks and ensure the gate moves smoothly.

Flange end gate valves are commonly used in applications where a full flow path with minimal pressure drop is required, and precise flow control is not critical. They are well-suited for applications where the valve needs to be either fully open or fully closed, such as in isolation and shut-off applications. However, it’s essential to consider the characteristics of gate valves carefully and ensure they are suitable for the specific requirements of the system in which they will be installed
