What is The TRI-Eccentric Butterfly Valve?
The TRI-Eccentric Butterfly Valve, also known as a triple offset butterfly valve, is a high-performance valve designed for critical applications where tight shutoff and durability are essential. Its innovative triple offset design minimizes wear on the valve seat, ensuring a longer service life and superior sealing capabilities. These valves are widely used in industries like oil & gas, power generation, chemical processing, and marine systems where extreme temperatures, high pressures, and zero leakage are vital requirements.
How TRI-Eccentric Butterfly Valves Work
The three offsets refer to the unique geometrical alignment of the valve’s disc and seat, which results in minimal friction during operation. The first two offsets ensure that the valve disc moves away from the seat without interference, while the third offset is an angular offset that provides the necessary cam-like movement for a metal-to-metal sealing without friction.
First Offset: The disc’s shaft is positioned slightly behind the centerline of the valve seat, reducing wear and ensuring smooth operation.
Second Offset: The disc is offset from the valve body’s centerline, ensuring that the disc rotates into the seat without dragging or wear.
Third Offset: The conical seat geometry ensures that the sealing surfaces engage without friction, providing a perfect, bubble-tight seal even under extreme conditions.
Key Features of TRI-Eccentric Butterfly Valves
Zero Leakage: The metal-to-metal sealing offers zero leakage, even under extreme temperature and pressure conditions, making it ideal for high-risk environments.
High Temperature and Pressure Resistance: Designed to withstand high temperatures and pressures, these valves are suitable for demanding applications like steam, gas, and hydrocarbon services.
Longer Service Life: The triple-offset design minimizes contact between the disc and the seat, reducing wear and ensuring longevity.
Bi-Directional Flow Control: TRI-eccentric butterfly valves provide effective shutoff in both flow directions, making them versatile for a variety of systems.
Low Torque Operation: Despite its high sealing capability, the valve operates with low torque, reducing energy consumption and allowing for easy automation.
Advantages of TRI-Eccentric Butterfly Valves
Reliable Sealing: The advanced triple offset design ensures a reliable, tight shutoff even in extreme conditions.
Durable Construction: Made from robust materials such as stainless steel, carbon steel, and alloys, these valves resist wear and corrosion, ensuring a long service life.
Cost-Effective: With minimal wear and lower maintenance requirements, TRI-eccentric valves provide a cost-effective solution over time.
Versatility: Suitable for use with various fluids including gases, steam, and hydrocarbons, in industries like oil & gas, chemical processing, and power generation.
