Understanding the Double Offset Butterfly Valve Design

Design Features

Válvulas de mariposa de doble compensación, also known as high-performance butterfly valves, have two offsets from the valve body’s center:

  • The shaft axis is offset from the disc’s seat and body seal’s centerline, y
  • The shaft axis is eccentric to the pipeline’s/valve’s center line.

This unique design helps minimize turbulence and ensures a tight seal, making these valves ideal for a variety of applications.

How They Work

A butterfly valve has flanges on both the inlet and outlet faces, lo que hace que la conexión entre la válvula y la tubería sea muy fácil y no tenga fugas. Además, el extremo de la tubería conectado con la válvula también está diseñado para tener el mismo tamaño que la brida y el orificio de la válvula embridada.. En general, these valves offer defect-free and worry-free performance.

Key Components

  1. Cuerpo: Typically made from durable materials like ductile (ASTM A536 /GGG40).
  2. Desct: All made in ASTM A536/ GGG40
  3. Provenir: Acero inoxidable: ASTM A182 304/316/431/ Acero inoxidable dúplex

Advantages of DN1400 Flange Dimensions Válvulas de mariposa de doble compensación

  1. Reduced Friction: The offset design minimizes contact between the disc and the seat, reduciendo la fricción y el desgaste.
  2. Cleanability: Due to the self cleaning(ningún residuo quedará atrapado) función, it’s also easy to clean and disinfect for potable water systems, etc..
  3. Lightweight and Compact: Compared to other valve types, double offset butterfly valves reduced weight and overall dimensions, making them easier to install and maintain.
  4. Versatilidad: Installation without restriction in the direction of flow (polished disc rim to avoid damage to the valve seat. Para la instalación no se necesita junta).
  5. Económico: Low-pressure loss and reduced energy costs. Good corrosion resistance.
  6. Multiple Option
    • Manual, actuador eléctrico, Actuador neumático, actuador hidráulico, and bare shaft are optional
    • Agua, agua potable, agua portatil, Aceite, seawater, and gas are all available working services.
    • El tamaño es de DN150-DN3600

Conclusión

Double offset butterfly valves play a vital role in fluid control across many industries. Their unique design offers significant advantages, including improved sealing, reduced wear, and versatility in application. Companies like TWT lead the way in providing high-quality valves that enhance efficiency and reduce costs.
