Triple Offset Butterfly Valve Benefits

tripple offset butterfly valve offer an array of benefits that make them an attractive solution for flow control. They offer high accuracy in flow regulation, are more durable and operate with lower torque requirements than other types of butterfly valves. Their unique design makes them efficient in applications with abrasive media, high pressure or temperature and even those that are prone to fugitive emissions.

The first point of difference between the double and triple offset butterfly valves is that the centerline of the valve seat doesn’t share the same centerline as the valve disc. This allows the cam-action to easily leave the disc, reducing unnecessary over-compression and scraping between the seats. This helps reduce wear and extends the life of the seal.

Understanding the Sealing Mechanism of Triple Offset Butterfly Valves

Secondly, the valve seat is machined to an offset conical shape that ensures the metal components never touch until the valve is fully closed. This eliminates friction between the valve seat and disc, further extending the seal life and eliminating the need for an elastomeric seat.

In addition to this, the valve body is optimized with Stellite to prevent wedging and binding that can occur when the valve is opened and closed quickly. Finally, the pin connector is positioned in the lower portion of the valve, which minimizes shaft deflection and improves thermal performance.
