Note: This gate valve cannot be used for drinking water.

The 4" wedge gate valve has a concealed stem design, which means the stem does not move up and down during operation, making it easier to install and maintain. The resilient wedge gate valve is equipped with a handwheel for easy manual operation and a flange end connection for easy installation.

Features

• 4" wedge gate valve features a gate with a wedge shape that allows for a tight seal when the valve is closed.
• DN 100 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 flexible 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 rising stem and a non-rising stem wedge gate valve?

A rising stem wedge gate valve and a non-rising stem wedge gate valve are two types of gate valves that differ in the design of their stems and the way they operate.

In a rising stem wedge gate valve, the stem of the valve rises above the valve body when the valve is opened, allowing for visual confirmation of the valve's position. As the valve is closed, the stem descends back into the valve body. This type of valve is often used in applications where visual confirmation of the valve position is necessary, such as in fire protection systems.

In contrast, a non-rising stem wedge gate valve has a stem that does not rise above the valve body when the valve is opened or closed. Instead, the stem rotates with the valve gate, which moves up and down within the valve body to control the flow of fluid. This design is useful in applications where space is limited or where there is a risk of damage to a rising stem valve due to external forces.

Both rising stem and non-rising stem wedge gate valves are reliable and commonly used in a wide range of industrial applications. The choice between them depends on the specific requirements of the application, such as the need for visual confirmation, space limitations, and external forces.
