A High-Performance Solution for Critical Applications

The TRI-Eccentric Butterfly Valve, often referred to as a triple offset butterfly valve, is a state-of-the-art valve specifically designed to deliver high-performance, tight shutoff in some of the most demanding environments. With a unique triple offset configuration, it provides exceptional durability, minimizes wear, and ensures long-lasting, reliable operation. This makes it a top choice for industries such as oil & gas, power generation, chemical processing, and marine systems, where operational reliability and zero leakage are essential.

How Does a TRI-Eccentric Butterfly Valve Work

The valve’s triple offset design refers to the precise positioning of the valve disc in relation to the valve seat, allowing for frictionless operation. Here's a breakdown of the three offsets:

First Offset: The disc's shaft is placed slightly behind the valve seat centerline. This offset reduces wear by allowing the disc to move smoothly during opening and closing.

Second Offset: The disc is further offset from the valve body’s centerline, ensuring the disc enters the seat without scraping, thus preserving the valve's integrity.

Third Offset: A conical seat design ensures the disc creates a metal-to-metal seal without friction, providing a bubble-tight shutoff even under extreme conditions.

This design minimizes wear on the seat and disc, ensuring longevity and top-tier performance, even in high-pressure and high-temperature scenarios.

Key Features of the TRI-Eccentric Butterfly Valve

Zero Leakage: The metal-to-metal sealing ensures a perfect, zero-leakage performance, even in high-risk, high-pressure environments.

Resistance to High Temperatures and Pressures: These valves are engineered to withstand extreme conditions, making them ideal for critical applications such as steam, gas, and hydrocarbon services.

Extended Service Life: Due to the minimized friction between the valve disc and seat, TRI-eccentric butterfly valves experience significantly less wear, ensuring a longer operational life and reduced maintenance costs.

Bi-Directional Shutoff: Capable of providing a tight seal in both flow directions, this valve offers flexibility in installation and operation.

Low Torque Operation: Even with its robust sealing performance, the valve requires minimal torque to operate, reducing the energy needed and allowing for easy integration with automated systems.

Advantages of TRI-Eccentric Butterfly Valves

Superior Sealing Capability: The triple offset design ensures reliable shutoff, even in extreme environments where other valves may fail.

Robust and Durable: Constructed from high-performance materials like stainless steel, carbon steel, and specialized alloys, TRI-eccentric valves offer exceptional resistance to corrosion and wear, making them ideal for long-term use in harsh environments.

Cost-Effective Solution: With minimal wear and reduced maintenance requirements, these valves provide a more economical solution over time compared to traditional valves, making them a sound investment for high-risk industries.

Versatile Applications: Whether dealing with gases, steam, or hydrocarbons, these valves excel across multiple industries, from chemical processing to power generation and oil & gas.
