n the world of industrial valves, triple offset butterfly valves are designed for a variety of different applications. These include corrosive and abrasive fluids, high pressures and temperatures. The main advantage of a triple eccentric valve is its sealing design, which results in an accurate bubble tight shutoff with zero leakage. This type of valve is suitable for both piping systems with and without strainers.URL:shiphamvalves.com
The geometry of the sealing components ensures friction-free stroking throughout the operating cycle. This allows for a lower torque actuator to be fitted and extends the valve life. The three-offset design also provides a more compact valve, which is easier to install and can be used in narrow spaces. The design eliminates cavities between the seal components, meaning there’s no place for debris to build up and increase maintenance costs.
This non-rubbing design is particularly important in abrasive and corrosive media, as it can significantly reduce the seat and seal wear of the valve’s rotating disc. This allows for the valve to open and close quickly and more reliably and extends its lifecycle.
Sealing the Deal: The Importance of Sealing Technology in Triple Offset Butterfly Valves
A key feature of the triple-offset design is that it eliminates rubbing between the seat and the elastomeric seat ring throughout the flow path. This can significantly reduce the wear of these materials, which means less maintenance and lower operating costs.
With its geometric design and angular offsets, the three-offset design allows for a more compact valve that is easier to install and use in narrow spaces. It also allows for a shorter stroke, which is more efficient and increases the valve’s speed of operation. This is especially beneficial in abrasive, corrosive, and steam environments.
