Double Eccentric Butterfly Valve Introduction
The double eccentric butterfly valve provides cost and space savings with a wide size range and faster operation. It minimizes wear and restriction between the disc and seat, ensuring a longer cycle life and lower total ownership costs. With its design offering extended operational life and reduced torque, it’s ideal for frequent use. The Bosseal high-performance valve has passed a million-cycle test, proving its durability.
Different End Connections Available
Dead End Service
For valves installed at the end of a pipeline where one side has no connection to a pipe or flange, special design features such as threaded holes and bi-directional sealing are required.
Easy Maintenance
The valve features a replaceable seat that can be easily serviced. Simply loosen the seat retainer using specialized tools to disassemble and replace the seat.
Fire Safe Seat
Our valve includes a fire-safe seat design with dual seals: a primary soft PTFE seat and a secondary metal seat. In the event of a fire, if the soft seat is compromised, the metal seat ensures effective shut-off.
