Triple Eccentric Type Butterfly Valves Water Transmission - High Pressure Line

Since their introduction to the market more than 50 years ago, triple offset valves (TOVs), which are also known as triple eccentric valves, have continued to evolve, while uses for this type of valve have expanded across multiple industries. Originally designed for water shut-off applications, design enhancements through the years placed this versatile butterfly valve among other industry staples for performance in the harshest conditions of critical process environments. At the same time, these valves have always had certain parameters within which they can operate effectively. TOVs offer countless benefits to the industry, and most recently they’ve received attention because of the role they can play in controlling fugitive emissions.
