Features

• 12" wedge gate valve features a gate with a wedge shape that allows for a tight seal when the valve is closed.
• DN 200 wedge gate valve has a full bore design, which means that the inside diameter of the valve is the same as the pipe it is connected to. This helps to minimize pressure drop and turbulence.
• The wedge gate valve is designed to allow for bi-directional flow, which means that fluid can flow through the valve in either direction.
• Wedge gate valves are capable of withstanding high pressures, making them ideal for use in applications where high pressures are present.
• When the valve is fully closed, the wedge gate provides a tight seal that prevents fluid from leaking through the valve.

Applications

Wedge gate valves are commonly used in various industrial applications, such as oil and gas, chemical, and petrochemical industries. These valves are designed to control the flow of fluid or gas by using a wedge-shaped gate that moves up and down to open or close the valve. 

Tips: What is the difference between a wedge gate valve and a knife gate valve?

A wedge gate valve and a knife gate valve are both types of valves commonly used in industrial applications to control the flow of fluids or gases.

While they may appear similar at first glance, there are some key differences between the two:

• Design: The wedge gate valve has a gate or wedge-shaped disk that moves up and down to control flow. The disk is usually attached to a stem that can be turned to raise or lower the gate. In contrast, the knife gate valve has a flat gate or blade that slides back and forth across the flow path to control
  flow.
• Application: Wedge gate valves are typically used in applications where a tight shutoff is required, such as in pipelines that transport liquids or gases. They are also commonly used in high-pressure applications. Knife gate valves, on the other hand, are often used in applications where the valve needs to be able to cut through thick or viscous fluids, such as wastewater treatment plants or pulp and paper mills.
• Sealing: Wedge gate valves rely on a wedge-shaped disk to create a tight seal against the valve body. Knife gate valves use a packing gland or other sealing mechanism to create a seal around the blade.
• Maintenance: Wedge gate valves can be more difficult to maintain than knife gate valves, as the gate and stem assembly can be prone to wear and damage.
• Knife gate valves are often designed with replaceable blades or seats, making them easier to maintain and repair.

Overall, the choice between a wedge gate valve and a knife gate valve will depend on the specific application and the requirements for the valve.
