Triple Eccentric Butterfly Valves vs Triple Offset Butterfly Valves

Triple Eccentric Butterfly Valves have three eccentricities between the disc and the valve body, namely axial eccentricity, radial eccentricity, and rotational eccentricity. This structure prevents the disc from direct contact with the valve body during rotation, thereby reducing friction and wear, and improving sealing performance and service life.

Triple offset butterfly valves have only two eccentricities between the disc and the valve body, namely axial eccentricity and radial eccentricity. The sealing performance and service life of this structure are better than those of ordinary butterfly valves, but worse than those of Triple Eccentric Butterfly Valves.

  • Sealing performance: Triple Eccentric Butterfly Valves have better sealing performance because the disc does not have direct contact with the valve body during rotation, thus reducing friction and wear.
  • Service life: Triple Eccentric Butterfly Valves have a longer service life because of their better sealing performance, less friction and wear.
  • Operating torque: Triple Eccentric Butterfly Valves have a smaller operating torque because the disc does not have direct contact with the valve body during rotation, thus reducing resistance.
  • Flow resistance: Triple Eccentric Butterfly Valves have a smaller flow resistance because the disc does not have direct contact with the valve body during rotation, thus reducing friction between the seat and the disc.

Applications of Triple Eccentric Butterfly Valves

Triple eccentric butterfly valves find applications in industries where reliable sealing, high-performance operation, and versatility are required. Some common applications include power plants, oil and gas, petrochemicals, water treatment, and process industries. They are used for regulating flow, isolating pipelines, and providing efficient control in demanding environments.

Conclusion

Triple eccentric butterfly valves are advanced valve solutions known for their exceptional sealing performance and high-performance operation. With their excellent sealing capabilities, wide temperature and pressure range, and bi-directional flow capability, triple eccentric butterfly valves offer reliable and efficient fluid control solutions.
