Mientras que seleccionar el tipo de válvula de mariposa más adecuado para los sistemas de control de flujo industrial puede ser un desafío, La verdad es que son esenciales. El diseño y las aplicaciones de la válvula de mariposa excéntrica triple, la válvula de mariposa compensada, and the Center Line Butterfly Valve make them different from each other. This guide identifies their differences in detail, lists their respective advantages, and points out their ideal use cases in order to give you the necessary information to choose the right valve.
1. Triple Eccentric Butterfly Valve: Advanced Design for Demanding Applications
ElTriple Eccentric Butterfly Valve is engineered for high-performance sealing in extreme conditions. Its three-layer offset design eliminates friction during operation, ensuring a long service life and bubble-tight shutoff.
Características clave:
- Metal seat construction – Suitable for high-temperature and high-pressure environments
- Fuga cero – Ideal for critical applications where sealing is essential
- Materiales resistentes a la corrosión – Works with aggressive media such as steam, ácidos, and hydrocarbons
Best Applications:
- Oleoductos y gasoductos
- Chemical and petrochemical processing
- Power plants and steam systems
For industries requiringmaximum reliability under harsh conditions, elTriple Eccentric Butterfly Valve is the optimal solution.
2. Offset Butterfly Valve: Enhanced Performance for General Industrial Use
ElOffset Butterfly Valve (also known as double eccentric) features a disc that is offset from the valve seat, reducing wear and improving sealing compared to standard butterfly valves.
Características clave:
- Reduced friction – Extends valve lifespan
- Improved sealing – Better performance than center line designs
- Versatile operation – Handles a wide range of pressures and temperatures
Best Applications:
- Plantas de tratamiento de agua
- sistemas de climatización
- General industrial fluid control
Forcost-effective yet reliable flow control, elOffset Butterfly Valve is an excellent choice.
3. Válvula de mariposa de línea central: Simple and Economical for Low-Pressure Systems
ElVálvula de mariposa de línea central is the most basic type, with a disc that rotates around a central axis. It is widely used in applications where tight sealing is not critical.
Características clave:
- Compact and lightweight – Easy to install and maintain
- Cost-effective – Ideal for budget-conscious projects
- Suitable for low-pressure systems – Works well with water, aire, and non-corrosive fluids
Best Applications:
- Municipal water supply
- Sistemas de riego
- Ventilation and air handling
Forlow-pressure, non-critical applications, elVálvula de mariposa de línea central provides a simple and economical solution.
Cómo elegir la válvula de mariposa adecuada?
| Tipo de válvula | Best For | La calificación de presión | Rendimiento de sellado |
|---|---|---|---|
| Triple excéntrico | High-pressure, a alta temperatura, fluidos corrosivos | Very High | Bubble-tight |
| Compensar | General industrial use, agua, climatización | Medium to High | Bien |
| Línea central | Low-pressure, non-critical systems | Low | Basic |
Final Recommendation
- For extreme conditions → Choose Triple Eccentric Butterfly Valve
- For balanced performance → Choose Offset Butterfly Valve
- For simple, low-cost solutions → Choose Válvula de mariposa de línea central
Understanding these differences ensures you select the best valve for your specific needs, optimizing performance and cost-efficiency.
