Triple Offset Butterfly Valve Advantages
Triple offset butterfly valves are a great choice for applications involving harsh media and mediums that have small particles that can clog traditional elastomeric-based butterfly valves. The unique design of the triple offset valve allows for more consistent sealing and longer life, which makes it an ideal choice for industrial environments where the conditions require robust equipment.Source:https://www.shiphamvalves.com/solution-category/triple-offset-butterfly-valves/
The key advantage of triple-offset valves is their cam action and right-angle conical seal. This results in very little contact between the valve disc and seat, reducing friction between them and extending the lifetime of the valve. Additionally, the lack of cavities between sealing components means there is no room for debris to clog the valve. This eliminates a significant source of maintenance costs and extends the lifespan of the valve.
The Advantages of Triple Offset Butterfly Valves in the Oil and Gas Industry
Another advantage of the triple-offset valve is its metal-to-metal sealing. This ensures bubble-tight shutoff and zero leakage performance, even under high-pressure applications and temperatures. In comparison, elastomeric-based butterfly valves often deteriorate under these conditions and are susceptible to corrosion. Triple-offset valves, on the other hand, use corrosion-resistant alloys for both the disc and seat, ensuring a lasting operation and excellent performance.
Triple-offset valves also feature optimized seat angles to minimize wedging and binding of the valve shaft, which reduces operating torque. This allows for easier stroking and less energy consumption, which also helps to extend the valve’s life. However, the most important factor when selecting a valve is finding one that will be compatible with your process’s specifications. Make sure that the valve is designed to withstand your system’s operating pressures and temperatures, and that it’s made of materials that are compatible with the surrounding environment.
