Description

South American Valve is one of the premier Lubricated plug Valve Supplier in Mexico. the main purpose of a lubricated plug valve is not just to reduce friction between the valve body and the plug but also to provide a tight seal, offer versatility in terms of size, ensure reliability in extreme conditions, and cater to a wide range of applications. These features make them a valuable choice for many industrial processes. The lubricated plug valve operates based on the principle of pressure equalization, which helps prevent the plug from getting locked against the body taper due to line pressure. This design also contributes to consistent torque requirements for operation.
In Mexico, the valve and its commitment to excellence shines through, making us the go-to choose for suppliers of Lubricated Plug Valve that meet the highest standards of performance and reliability.
How does it work?
1. Pressure Equalization: The key feature of this type of lubricated plug valve is the incorporation of two holes—one at the top and one at the bottom of the plug. These holes facilitate pressure equalization between different areas of the valve.
2. Upper Hole: The upper hole connects the plug’s port area with the top of the plug itself. This ensures that the pressure above the plug is equalized with the pressure in the port area.
3. Lower Hole: The lower hole maintains pressure equalization between the port area and the bottom of the plug. This balances the pressure below the plug with the pressure in the port area.
4. Preventing Plug Locking: By equalizing pressure both above and below the plug in the port area, the valve design prevents the line pressure from locking the plug against the body taper. This feature is crucial in ensuring that the valve can be operated smoothly without becoming seized or difficult to turn.
5. Predictable Torque: The pressure balance system ensures that the torque required to operate the valve remains predictable and consistent, even after the valve has been in the open or closed position for an extended period. This is advantageous for operators as it simplifies valve control and maintenance.
6. Dynamically Balanced Plug Valve: A valve with a pressure-balanced plug is sometimes referred to as a dynamically balanced plug valve because it maintains balance and ease of operation regardless of line pressure conditions.
