South American Valve is a leading Triple Offset Butterfly Valve Supplier in Brazil. A triple offset valve uses three offsets: one for the valve shaft, another for the disc/seat alignment, and a third for the cone-shaped seating surface. These offsets work in tandem to ensure a reliable, bubble-tight shut-off when the valve is closed, making it ideal for applications where absolute sealing is crucial, such as in the oil and gas industry or high-pressure steam systems.

South American Valve is a premier Triple Offset Butterfly Valve Supplier in Brazil. The third offset's geometry design ensures that the sealing components of the valve come together perfectly at a 90-degree angle during the closing process, serving as an effective mechanical stop. This precision engineering not only results in a bubble-tight shut-off but also prolongs the valve's operational integrity by reducing wear and eliminating any potential for over-travel, making it a reliable choice for critical applications.

Benefits

  1. Repeatable Sealing and Extended Life
  2. Bubble-Tight Shut-Off
  3. Suitability for Harsh Media
  4. Friction-Free Operation and Lower Torque
  5. No Clogging and Low Maintenance

Operation -

  • This differs significantly from that of a traditional butterfly valve. While a traditional butterfly valve pivots sideways like a handwaving motion to allow media flow when the lever is turned, the triple offset butterfly valve operates more akin to a globe valve.
  • In a triple offset butterfly valve, the disk's movement resembles that of a cone, as it moves both up and down within the valve body. As this cone-shaped disk adjusts its position, it eventually forms a circular sealing surface. What makes this design highly effective is that there is minimal friction or drag when the seat contacts the disk. This is achieved through the angled positioning of the disk in relation to the surface, allowing for smooth and efficient sealing.

Industry

  1. Oil and gas
  2. Pulp and paper
  3. Power generation
  4. Chemical
  5. Shipbuilding

Application-

  1. Triple offset butterfly valves excel in high-temperature and high-pressure environments, offering effective sealing and long-term durability, making them ideal for refining and petrochemical processes.
  2. These valves are crucial for regulating liquid flow in hydrocarbon processing due to their ability to handle high-pressure and high-temperature conditions without sideways motion during operation.
  3. Specifically designed for the hydrogen industry, triple offset butterfly valves operate differently from typical butterfly valves, offering precise control and reduced seat dragging.
  4. Used in oxygen plants to remove water from air, these valves eliminate sliding contact between the disc and seat, providing cost-effective and reliable performance.
  5. Essential for refrigerant fluid systems, triple offset butterfly valves provide efficient sealing, low maintenance, and durability in critical applications.
  6. Employed as pressure control valves in thermal fluid systems, these valves are designed for high-pressure scenarios and are adaptable to various industrial gas applications.
  7. With their triple offset design and material selection, these valves are widely used in the hot gases industry for their toughness and corrosion resistance.
  8. Triple offset butterfly valves find application in a wide range of piping and vacuum systems, resisting pocketing fluids, suitability for high-pressure and high-temperature services, and availability in hygienic and chemical-resistant varieties.
