Knife Gate Valve suppliers in UAE
Middleeast valve is the greatest Knife Gate Valve suppliers in UAE. We supply to cities like Abu Dhabi, Sharjah, Ajman, and Ajman.
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:
l In the open position, the gate of the valve is lifted away from the flow path, allowing material to flow through the valve unobstructed.
l This position is achieved by rotating a handwheel or using a motorized actuator, depending on the design.
2)Closed Position:
l In the closed position, the gate is lowered into the flow path, creating a seal that prevents material from passing through the valve.
l When closed, the gate presses against a sealing surface, which prevents any flow leakage.
3)Materials and Design:
l Knife gate valves are designed to handle different types of materials, including viscous fluids, slurries, and solids.
l The gate is often made of a material that can withstand abrasive substances and harsh conditions.
l The body of the valve can be made from various materials like stainless steel, cast iron, or other alloys.
4)Actuation:
l 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).
l Automation allows for remote control and integration into process control systems.
5)Sealing:
l The sealing arrangement is crucial in knife gate valves to prevent leaks when closed.
l 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 suppliers in UAE 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.
