¿Cuál es la diferencia entre la válvula de puerta y la válvula de mariposa??

Mar 3, 2025 | Noticias

Elegir entre una válvula de puerta y una válvula de mariposa puede ser difícil. Ambos tienen propósitos únicos y optimizan el rendimiento del sistema. Este artículo examina sus diferencias, características, y ventajas. We’ll look at the DN800 butterfly valve and BS5163 gate valve PN16. También, we’ll discuss butterfly valves in exhaust systems. Make an informed choice for your needs.

Butterfly Valve vs Gate Valve: Diferencias clave

1. Diseño y Operación

  • Válvula de compuerta: A gate valve employs a gate-like disc to block or allow flow. It lifts the gate with a multi-turn handwheel, ensuring minimal pressure drop when open.
  • Válvula de mariposa: A butterfly valve controls flow with a rotating disc and quarter-turn mechanism. This makes opening and closing quicker. It can also partially open to regulate flow.

2. Regulación de flujo

  • Válvula de compuerta: Ideal for on/off applications. It cannot regulate flow effectively due to potential turbulence and wear when partially open.
  • Válvula de mariposa: Suitable for both on/off and flow modulation. Its disc can be partially opened to throttle flow.

3. Pressure and Size

  • Válvula de compuerta: Handles higher pressures (up to PN16 or higher) and is preferred for smaller sizes.
  • Válvula de mariposa: Best for larger sizes, como un Válvula de mariposa DN800, where space and weight are concerns.

4. Instalación y mantenimiento

  • Válvula de compuerta: Needs more space and weighs more. Suitable for bi-directional flow systems and pigging operations.
  • Válvula de mariposa: More compact and lighter, easing installation and maintenance. Yet, its disc can interfere with pigging.

Applications of Gate Valve and Butterfly Valve

Gate Valve Applications

  • High-pressure systems (p.ej., Válvula de compuerta BS5163 PN16).
  • Systems requiring zero leakage and bi-directional flow.
  • Environments with thick fluids or slurries.

Butterfly Valve Applications

  • Large pipelines, como un Válvula de mariposa DN800.
  • Systems requiring flow modulation or quick shut-off.
  • Butterfly valve exhaust systems in industrial settings.
    • Butterfly Valve in Exhaust Systems: Butterfly valves control airflow in exhaust systems with quick operation and a compact design. They are ideal for industrial and automotive uses.
      • Key Benefits:
        • Fast Response: Quarter-turn operation enables rapid opening and closing.
        • Space Efficiency: Compact design fits into tight spaces easily.
        • Durabilidad: Made from stainless steel, ensuring longevity in harsh conditions.

Material and Standards

Válvula de compuerta

  • Materiales: Ductile iron body, stainless steel stem, and nitrile rubber disc.
  • Estándares: Complies with BS5163, GB/T24924-2010, and ANSI/AWWA C509-94.

Válvula de mariposa

  • Materiales: Acero carbono, acero inoxidable, or aluminum bronze body.
  • Seat Materials: EPDM, NBR, or Teflon for high-temperature resistance.
  • Estándares: Meets GB, ANSI, and API standards.

Advantages of Each Valve

Válvula de compuerta

  • High sealing tightness for zero leakage.
  • Suitable for high-pressure systems.
  • Una larga vida útil, up to 50 años.

Válvula de mariposa

  • Compact design saves space and reduces weight.
  • Cost-effective for large sizes like Válvula de mariposa DN800.
  • Quick operation reduces downtime.

Choosing between a gate valve and a butterfly valve depends on your system’s needs. For high-pressure, zero-leakage applications, a Válvula de compuerta BS5163 PN16 is ideal. For large pipelines or flow modulation, a DN800 butterfly valve is more suitable. In butterfly valve exhaust systems, its quick operation and compact design make it a top choice. Evaluate your requirements to make the best decision!
