Why L90 Butt Welded Hard Seal Triple Eccentric Butterfly Valves Are Ideal for High-Pressure, High-Te

27-06-2025

When dealing with high-pressure and high-temperature fluid control systems, you simply can’t compromise on valve performance. That’s where the L90 Butt Welded Hard Seal Triple Eccentric Butterfly Valve steps in as the go-to solution for engineers and buyers around the world. Whether you’re working in the oil & gas, chemical, power generation, or industrial pipeline sectors, this type of high-performance butterfly valve ensures reliable sealing and long service life—even in the harshest working conditions.

What Is a Triple Eccentric Butterfly Valve?

A triple eccentric butterfly valve, also known as a three eccentric valve, features a unique geometry: the shaft is offset in three positions. This smart design allows for zero friction during opening and closing, minimizing wear and ensuring tight shutoff, especially under high-pressure conditions.

The L90 series, specifically, is engineered with a hard metal-to-metal sealing surface, meaning it can withstand extreme temperatures and aggressive media. No rubber, no softness—just raw durability.

Why Choose the L90 Butt Welded Type?

The butt welded connection is a major plus for systems that prioritize leak-free performance and permanent installation. Here’s why customers love it:

  • Seamless connection: No flange, no bolt, just a full-penetration weld that’s rock solid.

  • Reduced pressure loss: With minimal flow obstruction, the valve ensures optimized fluid dynamics.

  • Low maintenance: Once it’s in, it stays put—and works hard for years.

If you ask us, butt welded valves are the "install it and forget it" champions of industrial pipelines.

Where Is the L90 Triple Eccentric Butterfly Valve Used?

This valve is tailor-made for demanding applications where safety, temperature resistance, and zero-leakage are top priorities. It’s widely used in:

  • Petrochemical pipelines

  • Refineries and gas processing

  • Steam and condensate systems

  • Power plants and nuclear energy

  • Industrial furnace and heating equipment

Actually, one of our clients installed this valve in a 480°C steam line—and it’s been working perfectly for over 3 years now. That’s what we call proven performance.

Key Features of the L90 Hard Seal Valve

  • Triple eccentric structure: Friction-free, precise movement

  • Metal-to-metal sealing: High sealing class with excellent temperature resistance
