Knife Gate Valve Suppliers
Valvesonly is the foremost Knife Gate Valve Suppliers in Germany. A knife gate valve is a type of valve that utilizes a flat gate or blade to control the flow of a fluid. The name "knife gate" comes from the blade's ability to cut through slurry and other thick fluids. These valves are primarily used to start or stop the flow of media rather than regulate it. When the valve is fully open, the gate is completely withdrawn from the flow path, offering minimal resistance and allowing for a full, unobstructed flow.
Working Theory of Knife Gate Valve
The working theory behind a knife gate valve is relatively straightforward. When the valve is in the open position, the gate is retracted into the valve body, allowing fluid to pass through. When the valve needs to be closed, the gate is lowered into the flow path, cutting through any material in its way and forming a tight seal. This action is typically achieved through a linear motion mechanism, which can be manual (handwheel or lever), pneumatic, or electric.
What Are Knife Gate Valves Best Used to Regulate the Flow Of?
Knife gate valves are specifically designed to handle slurries, viscous, corrosive, and abrasive fluids. These valves excel in applications where there is a need to cut through thick media, such as in pulp and paper mills, wastewater treatment plants, mining operations, and chemical processing. Their design allows them to slice through fibrous or particulate matter, making them ideal for systems where clogging is a common issue with other types of valves.
Knife gate valves are constructed with several key components:
· Body: Main structure housing all components, made from materials like stainless steel or cast iron.
· Gate (Blade): Flat, sharp-edged component that moves to open or close the valve, designed to cut through media.
· Seat: Sealing surface the gate presses against when closed, made from resilient materials like rubber or metal.
· Stem: Connects the gate to the actuator or handle, translating motion to open or close the valve.
· Packing: Seals the space around the stem to prevent fluid leakage.
