South American Valve is a best selling Triple Offset Butterfly Valve Supplier in Brazil. The triple offset design employed by these valves incorporates three key offsets: one for the valve shaft, another for aligning the disc and seat, and a third for the cone-shaped seating surface. These offsets synergistically contribute to achieving a reliable, bubble-tight shut-off when the valve is closed, making it especially well-suited for applications where absolute sealing is paramount, such as in the oil and gas industry or high-pressure steam systems.
South American Valve is a topmost Triple Offset Butterfly Valve Supplier in Brazil. This design ensures that the sealing components of the valve come together flawlessly at a precise 90-degree angle during the closing process, serving as an efficient mechanical stop. This meticulous engineering enhances the valve’s performance and reliability in critical industrial settings.
Benefits of Triple-Offset Valves:
· Repeatable Sealing and Extended Life
· Bubble-Tight Shut-Off
· Suitability for Harsh Media
· Friction-Free Operation and Lower Torque
· No Clogging and Low Maintenance
The functionality of a triple offset butterfly valve differs significantly from that of a traditional butterfly valve. Unlike the lateral pivoting motion of a traditional butterfly valve, which opens and closes like a hand-waving gesture when the lever is turned, the operation of a triple offset butterfly valve is more analogous to that of a globe valve.
In the case of a triple offset butterfly valve, the movement of the disk mimics that of a cone, executing both upward and downward motions within the valve body. As this cone-shaped disk adjusts its position, it eventually establishes a circular sealing surface. The effectiveness of this design is underscored by the minimal friction or drag encountered when the seat makes contact with the disk. This is made possible by the angled positioning of the disk relative to the surface, facilitating a seamless and efficient sealing process.
