A knife gate valve is a type of industrial valve designed primarily for on-off and isolation applications in systems that involve the flow of liquids or slurries containing solids. It is named “knife” gate valve due to its distinctive gate design that resembles a sharp-edged blade or knife.
Here’s how a knife gate valve typically works:

1)Open Position:
In the open position, the gate of the valve is lifted away from the flow path, allowing material to flow through the valve unobstructed.
This position is achieved by rotating a handwheel or using a motorized actuator, depending on the design.

2)Closed Position:
In the closed position, the gate is lowered into the flow path, creating a seal that prevents material from passing through the valve.
When closed, the gate presses against a sealing surface, which prevents any flow leakage.

3)Materials and Design:
Knife gate valves are designed to handle different types of materials, including viscous fluids, slurries, and solids.
The gate is often made of a material that can withstand abrasive substances and harsh conditions.
The body of the valve can be made from various materials like stainless steel, cast iron, or other alloys.

4)Actuation:
The actuation mechanism varies depending on the application and the valve’s size. It can be manual (handwheel operation) or automated (electric, pneumatic, or hydraulic actuator).
Automation allows for remote control and integration into process control systems.

5)Sealing:
The sealing arrangement is crucial in knife gate valves to prevent leaks when closed.
Some valves have soft seals, such as rubber or elastomers, to provide a tight seal against the gate. Metal-to-metal seals are also common for more rugged applications.

Middleeast valve is the best Knife gate valve supplier in Dubai and are primarily designed for applications where a tight shut-off is not critical, and the valves are not typically used for regulating the flow rate.
