Triple Offset Butterfly Valve Benefits
Unlike valves with a traditional seat/seal arrangement, triple offset butterfly valves operate using the contact pressure of their sealing surfaces. This creates a metal-to-metal seal which eliminates leakage and guarantees bubble-tight shut-off. Their unique geometry design makes them a highly efficient choice for a wide range of applications. This article explores the benefits of these high-performance valves for demanding fluid handling applications including oil and gas, chemical, petrochemical, nuclear, and power.This link:https://www.shiphamvalves.com/solution-category/triple-offset-butterfly-valves/
Triple Offset: The Geometry Design
The geometry of the three-offset butterfly valve enables a cam-like motion which allows the disc and seat to only make contact during the final stage of closure, minimizing friction between the sealing surfaces. This translates to less wear and tear on the seat and disc, resulting in a significantly extended lifespan. The absence of cavities between the sealing components also means no room for debris to clog, which reduces maintenance costs and further extends the valve life.
Corrosion Resistance: The unique construction of these valves enables them to handle harsh media with ease, unlike other valve types that use soft or elastomeric seat materials that may deteriorate due to temperature or exposure to chemicals. Triple-offset butterfly valves can be used to regulate a variety of liquids, gases, and solids including food, coatings, and some types of acidic media.
As with any type of valve, proper installation and maintenance are essential for optimal performance and safety. During installation, it is important to ensure that the valve is properly aligned in the piping system and inserted into a flange with appropriate ratings for both torque and pressure. It is also important to follow the manufacturer’s recommended lubrication and cleaning routines to minimize wear. Lastly, regular inspections should be performed to look for any signs of damage or leakage.
