Triple Offset Butterfly Valve: Working Principle, Applications (2025 Update)

Introduction

Triple offset butterfly valves are widely adopted in high-pressure and cryogenic applications due to their zero-leakage performance and compliance with API 609 standards. As of 2024, these valves are essential components in industries such as oil & gas, chemical processing, and power

A Triple Offset Butterfly Valve (TOBV) is an advanced type of butterfly valve designed to provide metal-to-metal sealing with zero leakage under high-pressure and high-temperature conditions. Unlike traditional butterfly valves, TOBVs use three offset angles in their design to eliminate friction and wear between the disc and seat.

Key Components

• Disc

• Shaft

• Seat

• Bearings

• Sealing Ring

The three offset design creates a conical sealing surface, which ensures that the disc only makes contact with the seat at the final degree of closure, eliminating friction and wear during operation.

Offset Explanation:

This design provides bi-directional zero-leakage performance (API 598).

Applications in High-Pressure & High-Temperature Industries

• Oil & Gas Pipelines

• LNG Terminals

• Petrochemical Plants

• Power Generation

• Refinery Isolation Systems

• Cryogenic Applications
