CARZ

CARZ

Válvula de aislamiento de explosión CARZ - sistema de protección.

La válvula de mariposa CAR con aislamiento anti explosión está diseñada como equipo resistente a la presión generada, y es capaz de prevenir la transmisión de las llamas y la presión aguas arriba de la instalación.
Descripción
Construcción soldada en RAL 5009 pintada en azul con placa de acero o acero inoxidable con un fuerte sello de goma, que está disponible bajo petición.
Función
Durante el caudal de aire generado por el ventilador principal, la placa de la aleta está abierta. En caso de una explosión en el equipo aguas abajo (por ejemplo, colector de polvo) una onda de presión obligará a cerrar la placa de la aleta y bloquearla en posición. Gran ángulo de apertura para asegurar una baja caída de presión. Cuando la placa de la aleta se cierra hace de barrera eficaz frente al avance del frente de llama. Esto previene que la explosión se transmita a las áreas de trabajo, aguas arriba de la instalación.

  • Independently tested according to current standards and regulations
  • Compliant with most international dust explosion protection codes (ATEX and NFPA68)
  • Widest range of sizes, applications and filter system configurations on the market (incl. approval for positive and negative pressure systems)
  • Manufactured fully by Nederman under certified quality assurance system, ensuring highest level of quality and reliability
