Product Description

 

A Double Flange Triple Offset Butterfly Valve is a type of industrial valve designed to control the flow of fluids (liquids or gases) within pipelines. It's called "double flange" because it has flanges on both ends, allowing for easy installation between pipe flanges without the need for additional hardware like nuts and bolts. The term "triple offset" refers to the unique geometry of the valve's sealing mechanism.

 

Triple offset butterfly valves offer several features and benefits that make them high-performance solutions for industrial applications. These include:

1. Zero Leakage: The triple offset design allows for a tight seal that prevents leakage, even in high-pressure and high-temperature applications. This reduces the risk of product loss, environmental damage, and safety hazards.
2. High Performance: Triple offset butterfly valves can handle high pressures and temperatures. Making them ideal for applications in industries such as oil and gas, chemical, and power generation.
3. Low Torque: The triple offset butterfly valve design requires less torque to operate, reducing the operation and maintenance cost.
4. Long Lifespan: Triple offset butterfly valves are highly durable. And resistant to wear and tear, resulting in a longer lifespan and reduced replacement costs.

Triple Offset Design: Unlike traditional butterfly valves that use a concentric or single offset design, the triple offset design features three distinct offsets:

First Offset: The shaft is offset from the centerline of the bore, reducing wear and tear on the sealing components.
Second Offset: The disc is also offset from the centerline, providing a cam-like action during rotation to ensure tight sealing.
Third Offset: This refers to the conical shape of the sealing surface. As the valve closes, the sealing surface makes contact at a specific angle, minimizing friction and wear, and providing a tight shut-off.
Double Flange: The double flange configuration means the valve has flanges at both ends, making it easier to install and remove from the pipeline. These flanges are typically designed to conform to industry standards for compatibility with existing piping systems.

Material and Construction: Double Flange Triple Offset Butterfly Valves are commonly made from materials such as stainless steel, carbon steel, or exotic alloys depending on the application requirements. They are robustly constructed to withstand high pressures and temperatures, making them suitable for various industries including oil and gas, petrochemical, power generation, and water treatment.

High Performance: The triple offset design provides several advantages over traditional butterfly valves, including reduced wear and tear, improved sealing performance, and increased longevity. These valves are often used in critical applications where tight shut-off and reliable operation are essential.

Maintenance

Proper maintenance is essential for ensuring the optimal performance and lifespan of triple-offset butterfly valves. Maintenance tasks include:

1. Regular Inspection: Regular inspection of the valve body, disc, and seat can help identify any signs of wear and tear or damage.
2. Lubrication: Proper lubrication can help reduce friction and wear, as well as prevent corrosion.
3. Cleaning: Regular cleaning can help prevent the buildup of debris and contaminants that can cause damage to the valve.
